About me (EN)

My research focusses on the mineralogy and geochemistry of igneous rocks and associated rare metal deposits. In April 2021 I started as an assistant professor in the Ore Geology and Geofluids group at KU Leuven and as senior researcher at the Royal Museum for Central Africa. In this role my research focusses on granitic pegmatite and quartz vein hosted Sn-W-Ta-Nb-Li mineralisation in the Mesoproterozoic Karagwe-Ankole Belt in Rwanda, Burundi and DRC, and continue research on alkaline and carbonatite hosted REE-P-Zr mineralisation.

I was born and raised in a small town in South Holland, stereotypically Dutch: a few meters below sea level and surrounded by cows and windmills. I studied Earth Sciences at the VU University Amsterdam, where I completed my BSc in 2009 and my MSc in 2012 in the research group of Prof Gareth Davies. Immediately after graduating I started my PhD at the Geological Survey of Denmark and Greenland and the University of Copenhagen, under the supervision of Prof. Tod Waight, Dr Troels Nielsen, and Dr Henrik Friis.

My PhD thesis focussed on the complex magmatic and hydrothermal evolution of highly peralkaline nepheline syenites in the rift-related Gardar province in South Greenland, specifically looking at REE-Zr-Nb mineralisation (metals we need for modern technologies). I defended in June 2016, shortly after which I moved to Scotland to start a postdoc at the University of St Andrews with Prof. Adrian Finch.

As a postdoc I continued to work on eudialyte-hosted REE deposits in South Greenland, and various other mineral deposits, initially as part of the NERC funded SoS RARE consortium. The SoS RARE project was a UK-based consortium with partners at the University of Brighton, Leeds, Sheffield, Exeter (Camborne School of Mines) and the BGS. The aim of the project was to bring together mineralogists, geochemists and metallurgists to improve our understanding of the processes by which metals get concentrated into rocks to levels at which they can be mined, and to use this information to develop environmentally friendly and economically viable ways to extract the metals from these resources.

I am particularly interested in how late-magmatic fluids evolve and modify the primary mineralogy, and how this influences the processing steps required to extract the metals from the rock. I use radiogenic isotopes (U-Pb, Sm-Nd, Rb-Sr, Lu-Hf) to trace subsolidus mobility of elements and to fingerprint the source of critical metal enrichment. I also use various mineral chemical techniques, such as EMP, XRD, and synchrotron-based X-ray Absorption Spectroscopy, to characterise the structure and elemental composition of minerals. As part of SoSRARE I have also worked on heavy rare earth enriched Ion Adsorption Deposits in weathered igneous rocks from Madagascar and China with collaborators from the University of Brighton and the British Geological Survey.

In St Andrews I’ve been involved in teaching undergrad level BSc, MGeol and MSc courses in magmatic ore deposits and igneous petrology, demonstrating lab practicals in optical microscopy, field-mapping courses (Mull & Rum), and supervised various dissertation projects.

I was awarded the 2021 Max Hey Medal from the Mineralogical Society of Great Britain and Ireland, for my contributions in mineralogy and petrology, as well as the 2021 R.A. Howie Best Paper Award for our paper entitled  “Structural state of rare earth elements in eudialyte-group minerals” in Mineralogical Magazine – which combined synchrotron techniques and lattice strain theory to identify where rare earth elements sit inside the crystal structure of eudialyte.

New Paper on the Adsorption of Rare Earths in Lateritic Clay Deposits, published in Nature Communications

September 2020

Subtropical weathering profiles developed on granites in Southern China are the worlds dominant source for heavy rare earth elements (HREE); metals that are crucial in many user electronics and green technologies. In these weathering profiles, feldspars and other magmatic minerals that contain REE break down to form secondary clay minerals. In the process of soil formation, REE are released from the minerals and are generally  inferred to adsorb loosely to the surfaces of secondary minerals, dominantly clays and Fe-Mn oxides.

Although these so-called ‘ion adsorption deposits’ are typically very low grade compared to magmatic REE deposits (carbonatites/alkaline rocks), exploitation of these resources is economically viable because the REE can be extracted at low cost via surface or heap leaching. The key requirement for this to work is that the REE are indeed adsorbed to the surfaces of clay minerals, instead of being hosted in insoluble secondary or relict mineral phases.

In our new paper published in Nature Communications (Open Access: https://lnkd.in/dJf46UH) we compare the mineralogy and distribution of #REE in prospective weathering profiles from the peralkaline #Ambohimirahavavy Complex in #Madagascar to economically exploited weathering profiles from the #Zhaibei Granite in #China.

Specifically, we use X-ray Absorption Spectroscopy to find out exactly where the #REE were hiding in lateritic soil profiles from Madagascar and China.

Although primary mineralogy plays a key role in the development of easily-leachable REE deposits formed by weathering, we found that the adsorption mechanisms of REE to clay minerals, at the atomic level, are identical at both sites.

Our data demonstrates that Yttrium, as a proxy for the heavy REE, is dominantly adsorbed as 8 to 9-fold hydrated outer sphere complexes to clay minerals, dominantly kaolinite and minor halloysite. This proves the general assumption that the REE are adsorbed to clay minerals, and justifies the name ‘Ion Adsorption Clay Deposits’ for these ore types.

Alkaline Igneous Rocks and potential Critical Metal deposits in Angola

Workshop and fieldtrip, September 2019

3/10/2019

In September, the St Andrews team took part in a workshop and fieldcourse in Angola, hosted by the Universidade Agostinho Neto (UAN) in Luanda. The purpose of our trip was to outreach our work on alkaline igneous rocks and to learn more about similar rocks found in Angola. Our visit started with a day workshop on frontiers in the study of alkaline silicate rocks and carbonatites, which included presentations by Prof Adrian Finch and myself (University of St Andrews) and by Pete Siegfried of GeoAfrica Consultants (based in Namibia). GeoAfrica and St Andrews are both partners within the HiTech AlkCarb consortium, funded by the European Union.  Our visit was funded by the SFC ODA Global Challenges Research Fund as the first step in assessing opportunities for future collaborations between Angola and St Andrews for sustainable development of their mineral resources. The workshop was hosted by the Universidade Agostinho Neto at their campus in central Luanda on the Avenida Marginale, and was followed by 5 days of fieldwork in an underexplored nepheline syenite complex (Nejoio) in the remote northern part of the Namibe province.

Workshop Luanda

The workshop in Luanda was attended by about 60 geologists working in Angola, including representatives from the University, the Angolan Oil company Sonangol,  recent Angolan graduates and many of the geology, geophysics and engineering students from the Agostinho Neto University.  At the workshop we presented scientific work on magmatic roof zones (Adrian), mineralisation processes in peralkaline systems in Greenland (myself), and on carbonatites in Namibia and South Africa (Pete Siegfried, GeoAfrica Prospecting Services).  

Fieldtrip Nejoio complex, South Angola

The workshop in Luanda was followed by a 5 day fieldtrip looking at peralkaline igneous rocks at the Nejoio complex in Southern Angola. We were based in the town of Camacuio in Namibe Province, roughly 6 hours north of Lubango, and at a c. 3.5 hour drive from the field site which lies on the land of the Muhumbi people. This visit was an opportunity for us to learn more about working in Angola and also to assist the Angolan geologists with the interpretation of their geology using our experience of similar rocks from Greenland, Brazil and Namibia. The group included Finch, Borst and Siegfried accompanied by Professor Aurora Bambi of the Universidade Agonstinho Neto in Luanda. The course was also attended by two recent geology graduates from St Andrews (Geraldine Tchimbali and Antonia dos Santos) and four current geology students from the Agostinho Neto University (Andre Eugenio, Egidio Lopes, Elizabeth Faria and Sergio Azevedo) who will use the field course as part of their undergraduate dissertations.

It was a pleasure and a privilege for us to work alongside the geologists from the Agostinho Neto University in Luanda, allowing us insights into the complex and fascinating geology of Angola, and allowing Angolan geologists access to the expertise we have acquired from rocks elsewhere in the world. A key objective of the project was to place Angolan geology within the broader regional context of South West Africa (i.e. South Africa, Namibia, Angola).

Nejoio is spelled in different ways, including N’DJOIO, NANDJOIO AND NEDJOIO, following attempts to translate locality names in the Kimbundu language into Portuguese. We have used Nejoio to be consistent with existing scientific literature by Rodrigues et al.
Research on Nejoio was carried out thanks to kind permission of Soba (Chief) Nangolo of the Muhumbi People on whose land the complex lies.
The fieldwork and attendance by BORST and FINCH were sponsored by the SFC ODA GLOBAL CHALLENGES RESEARCH FUND.
The attendance of Peter Siegfried was supported by the HITECH ALKCARB project, funded through the European Union h+Horizon 2010 Research and Innovation Programme (#689909)

Jolan has been part of my group for the last two years, studying spodumene textures and alteration processes in LCT pegmatites from the Musha-Ntunga Li-Ta-Sn deposits, exploited by Trinity Metals Ltd. Jolan works on beautiful pegmatite drill core samples, and is co-supervised by myself and Stijn Dewaele (UGent). Very glad to have Jolan in our team for another 4 years.

Kinderuniversiteit: Minecraft en Geologie

October 2022

Op zaterdag 22 oktober nam ik namens de afdeling Geologie deel aan de Kinderuniversiteit op Campus Arenberg met een hoorcollege over Minecraft en twee workshops over Vulkanen.

230 kinderen schreven zich in voor mijn kindercollege ‘Minecraft en Geologie’. Wat een super leuk publiek was dat!

Ouders konden ook live meekijken in de naastgelegen aula. Minecraft is een populaire game onder scholieren en blijkt dus een zeer effectief medium om de jongere generatie te informeren over geowetenschappen en het belang van stenen en mineralen voor de maatschappij en de energietransitie.

Na het college volgden er verschillende workshops, waaronder twee workshops over vulkanen waarbij 50 kindjes experimenteerde met proefjes over de viscositeit van magma en explosiviteit van vulkanen. Dank aan de studenten die meehielpen aan de workshops, Jolan Acke, Nick van Faals, Michael Steenhuyse en Hella Devriese, en Anne Oldenhage voor het mooie initiatief.

Ore Deposits Hub talk

Dec 2021

In the link below you’ll find my live streamed ODH talk and discussion on Peralkaline Magmas and Critical Metal Resources, providing an overview of recent research I have worked on within the SoSRARE and HiTechAlkCarb projects. The talk also introduces two new/upcoming papers (one on fenitisation procesess published in Geology, and one currently under revision in Economic Geology). Not my best talk ever – but hope it gives a nice overview on the peculiar world of peralkaline rocks.

Interview with KU Leuven SIM2

Sept 2021

In this interview with the KU Leuven Institute for Sustainable Metals and Minerals (SIM²) I share some thoughts on the public perception of mining and the challenges around sourcing the materials needed for the green-energy transition.

We must go ‘green’ and we must do it fast. The catch is that we cannot become carbon-neutral without mining, and we cannot become carbon-neutral if the raw materials we import were mined under unfair or unsustainable conditions. If we source our raw materials elsewhere, we – as consumers and fellow inhabitants of planet Earth – have a responsibility to make sure they were extracted to similar standards as if they were mined from our own backyards. Easy to say, not so easy to do.

“Mining of critical metals has to bring economic and social benefits to Africa”

Starting a new position!

I’m excited to announce that on April 1st 2021 I’ll be starting a new position at KU Leuven and the Royal Museum for Central Africa, where I’ll be conducting research on magmatic-hydrothermal ore deposits of Sn-W-Li-Ta-Nb-REE-P and other critical metals in Central Africa.

The past 5 years at the University of St Andrews have been wonderful, and I am grateful for the many opportunities and lovely people I met along the way!

I will miss Scotland and everyone at the School of Earth and Environmental Sciences, but am looking forward to this exciting next chapter with new areas of research and collaborations. If you are working in geological exploration in Central Africa and would like to connect/collaborate, please send me a PM.

Sulfur Isotopes Paper Published in Nature Communications

16/09/2019

Our research led by Will Hutchison on sulfur isotopes of alkaline magmas is now published Open Access in Nature Communications. The work was led by the St Andrews team in collaboration with colleagues at Tübingen and Glasgow Universities. The group at St Andrews included four of our group (Will Hutchison, Adrian Finch, Nicky Horsburgh and Anouk Borst), our colleague Eva Stüeken (who works on chalcogen isotope fractionation) and Henrik Friis who is now Associate Professor at the University of Oslo.

Will compared the mantle signatures of Gardar magmas in Greenland with a compilation of data for alkaline igneous rocks across the globe. Variations in mantle sulfur signatures matched gross trends in the isotope values of the contemporary surface, which changed dramatically over Earth History. He concluded that the sulfur in the Gardar magmas contained a component that had been recycled from the Earth’s surface.

The exciting conclusion is that the Earth’s sulfur cycle contains a significant component of surface sulfur being recycled back into the mantle. Will’s work draws attention to how useful alkaline igneous rocks are as windows on the composition of the sub-continental mantle through geological time.

New paper out in special Rare Earth issue of Minerals

10/07/2019

In this study we quantify gains and losses of critical elements during late-magmatic hydrothermal alteration of eudialyte in the Ilimaussaq complex, Greenland. By microdrilling the alteration products of eudialyte – the primary host for REE, Zr and Nb – we found that certain metals (particularly those just mentioned) may be more mobile in the hydrothermal environment than we previously thought.

EudialyteAlteration-VandeVen et al 2019
Red kakortokite sample from Unit 0 showing relative proportions of fresh eudialyte (red, c. 30%), replacement products after eudialyte (brown, c. 30%) and remaining minerals (feldspar, nepheline, sodic amphibole, c. 40%)

The alteration led to significant losses in Rare Earths and other High Field Strength Elements, and small gains in Large Ion Lithophile Elements (Rb, Th, U). We suspect that the elements that were removed from eudialyte by the fluids re-precipitated elsewhere in the rock. As such we infer that the alteration did not significantly influence the overall ore grade of the deposit. However, it does influence the ease by which we can extract the metals from the rock, as the metals are now hosted in a plethora of fine-grained intergrowths of secondary minerals. This has important implications for ore potential and mineral processing schemes of eudialyte-hosted ores, if we are to exploit these as a future source for green-technology metals.

Brazil 2017

Brazillian Rare Earth symposium – University of São Paulo

On 6 to 10 November 2017, the St Andrews team (Nicky Horsburgh, Adrian Finch and myself) attended the Brazilian SOS RARE symposium on Rare Earth Elements, held at the Institute of Geosciences, University of São Paulo. The symposium was organized by Prof. Daniel Atencio and Prof. Marcello Andrade (University of São Paulo) and comprised a series of invited talks followed by field excursions to famous Brazilian carbonatite and peralkaline localities.

Prof. Marcello Andrade kicked off the meeting with a presentation on Raman spectroscopy to fingerprint REE minerals. Dr Andrezza de Almeida Azzi (USP) introduced us to the fascinating geology and mineralogy of the Poços de Caldas alkaline complex. She catalogued many REE minerals from old sample collections of former Poços de Caldas mining sites, many of which are not properly documented to date. Prof. Daniel Atencio gave us a preview of the bewildering mineralogy of the Araxa and Jacupiranga carbonatites.

After lunch and an enjoyable visit to the local mineral museum, Prof. Hermi Felinto de Brito from the Institute of Chemistry (USP) talked about the luminescent properties of RE3+ compounds and the synthesis of persistent luminescent Eu, Tb and Tm materials which can luminesce up to 24 hours after being excited, offering many applications in for example traffic and emergency signalization. Prof. Brito also demonstrated how they synthesize RE3+compounds at high temperature using just a simple microwave oven.

Prof. Henrique Kahn of the Mining & Engineering department of the LCT-Polytechnic School (USP) presented work on metallurgical processing and mineralogical characterization of REE-rich lateritic soils from various Brazilian carbonatite localities. The last three talks were given by us from St Andrews. Prof. Adrian Finch spoke about REE and HFSE mineralisation in magmatic roof zones and applications of luminescence studies to understand hydrothermal alteration and mineralization processes. I presented on the pseudomorphic replacement of eudialyte in the Ilímaussaq complex, including new evidence for late-magmatic REE-HFSE remobilisation from trace element and Sm/Nd isotopic data of microdrilled pseudomorphs (work by my MSc student Mathijs vd Ven). Nicky Horsburgh gave the last talk, on luminescence studies of REE minerals. Nicky demonstrated that mineral luminescence is strongly provenance dependent, illustrating the need for site-specific luminescence studies if we are to apply luminescence as an automated sorting or core logging tool.

Keen to bring out our geological hammers, we ventured north of São Paulo on day two to see some rocks in the field. After a long bus journey, enjoying the luscious green scenery, we arrived at an amazing lujavrite outcrop in the northern part of the Poços de Caldas alkaline complex. This is one of the few places with good solid rock exposures, not obscured by the thick tropical weathering profile that covers much of the complex. The coarse grained lujavrite shows strong magmatic foliation fabrics defined by coarse feldspar laths wrapped in fine needles of aegirine (photo), which is a testament of the low viscosity melt and possibly subsolidus deformation and recrystallisation. The rock is peppered with large (5–6 cm) purple to pink eudialyte which overgrow the foliation fabric, resembling textures seen in the naujaite of the Ilímaussaq complex. We managed to collect a number of samples for further mineralogical studies and comparison to Greenland samples.

My research on eudialyte and rare earths

[Photo credit: Ole Johnsen]

Much of my research focuses on a rare breed of magmatic rocks known as agpaitic nepheline syenites. These rocks are fascinating to geologists, mineralogists and geeks alike, for many reasons. To me, the most obvious reason is their incredible mineralogical diversity. Hundreds of minerals were first discovered from these rocks; sodalite, aegirine, arfvedsonite, eudialyte are only a few examples. Famous agpaitic complexes in terms of the number of new mineral discoveries, include Mont St Hilaire in Canada, Lovozero and Khibina in Russia, and Ilímaussaq in Greenland. And when I say mineralogically diverse, I mean that if you pick up any rock from these locations, chances are it contains a mineral that no one has yet identified or named. Also, they’re very pretty and colourful (especially under UV light).

Another reason why we are interested in these peculiar rock types is that agpaitic rocks present one of very few examples where magmatic enrichment processes alone led to the formation of potentially economic ore deposits of elements like Zr, Nb, Ta, Hf, and Rare Earth Elements. For a magma to become so enriched these elements, the magma needs to fractionate extensively and become highly enriched sodium and halogens. This requires a rather unique set of conditions. Normally, sodium and halogens are lost as soon as a fluid phase exsolves from the magma. Only in certain geodynamic settings, such as in continental rifts, magmas may be so reduced that volatiles remain dissolved in the melt until the very last stages. This subsequently increases the solubility of incompatible elements and significantly lowers the crystallisation temperatures. This is partly why agpaitic rocks are relatively rare in the rock record.

The most diagnostic ‘hallmark’ mineral of agpaitic rocks is eudialyte. Eudialyte group minerals are complex sodium-rich zirconosilicates with calcium, iron, manganese, niobium, and rare earth elements. Where most igneous rocks contain zircon or ilmenite as the main hosts for zirconium and titanium (i.e. high field strength elements), agpaitic rocks contain complex sodium and halogen bearing minerals like eudialyte, rinkite (Na-REE-Ti-silicate) and aenigmatite (Na-Fe-Ti-silicate). Eudialyte most commonly occurs as brown, red to pink crystals, such as on the pictures below, but orange and yellow varieties are also known.

Eudialyte group minerals were first discovered in 1819, in the layered Ilímaussaq complex where they occur in large quantities. The mineral has now been reported from over 100 localities world-wide. Because they occur in such large quantities, eudialyte group minerals are considered as potential alternative resources for a range of technology metals, notably the heavy rare earths and niobium. These metals are crucial components in modern-day technologies, ranging from permanent magnets used in smart phone speakers, car engines or big wind-turbines [made of NdFeB], to rare-earth phosphors giving colour to the screens in our electronic devices [using Ce, Eu, Gd, Tb and Y]. Niobium has important anticorrosive properties and significantly enhances the strength, flexibility and general lifetime of steel.

The problem with rare earth elements, as well as niobium, is that their supply chain is controlled by single producing countries. Most of the world’s heavy rare earths come from China, and most niobium comes from a single mine in Brazil. Needless to say, monopoly market positions are risky because disruptions in the supply chain of these metals could strangle global hi-tech industries. For this reason, governments around the world are working closely with geologists and exploration companies to seek and develop alternative resources and to safe-guard global supply chains of these so-called ‘critical’ or ‘strategic’ metals.

Eudialyte-hosted REE deposits, such as in the Ilímaussaq complex, form an attractive alternative and current work focusses on developing cheap and environmentally friendly ways to extract the metals from these minerals.

My research specifically aims to understand how zoned crystals of eudialyte can be used to trace the evolution of the highly evolved magmas from which they crystallised, how they are replaced by secondary minerals when late-magmatic fluids percolate through the rocks after they crystallised, and how this affects the ore potential.

In more recent work, I’ve worked out where inside the complex crystal structure of eudialyte the REE’s are hiding, using synchrotron-based techniques such as XANES and EXAFS. These techniques allow me to probe the type, number and distance of atoms surrounding the REE atoms inside the crystal lattice.
