New Lithos paper out

Dating agpaitic rocks: A multi-system (U/Pb, Sm/Nd, Rb/Sr and 40Ar/39Ar) isotopic study of layered nepheline syenites from the Ilímaussaq complex, Greenland, Lithos. https://doi.org/10.1016/j.lithos.2018.10.037

Happy to announce that the last paper of my PhD is accepted in Lithos. In this work we investigated the effects of late-magmatic alteration on different radiogenic isotopic systems and explore whether or not the ‘old-fashioned’ isochron technique can provide suitable age constraints from rocks that characteristically lack phases (zircon, baddeleyite) for high precision U-Pb dating.

Here’s a 50-day access link to the paper: https://authors.elsevier.com/a/1Y2PP_Zf9y1Y2

Blog

Below is a link to a guest blog I wrote with Dr. Will Hutchison for the EGU Geochemistry, Mineralogy, Petrology & Volcanology website.

The Fractional Crystallization Freak Zone

Will is a fellow postdoctoral researcher here at St Andrews. He studies active volcanoes and ancient magma chambers, and is currently working on the roof zones of  alkaline magmatic systems in Greenland, as part of the Horizon2020 funded HiTech AlkCarb consortium.
