Happy to get started at @carnegiescience.bsky.social today as a postdoctoral fellow! Looking forward to tackling hydrogen formation during subduction again #geology #hydrogen

Our timescales are similar to time intervals between intrusions recorded by geophysical means in more mature rifts. The magmatic systems that facilitate late-stage rifting have already developed before substantial thinning of the rifting plate under Ethiopia. 5/6

Modelling Fe-Mg diffusion across these crystals, we conclude that high-Mg magmas and olivine crystals from the lower crust are injected and mixed into lower Mg magmas and crystals in the mid-crust, weeks–months before eruption. 4/6

Compositional zones in olivine crystals are evidence for pre-eruptive chemical disequilibrium resulting from magma movement. We see two types of zoning from MER scoria cone fields: higher Mg cores/lower Mg rims (a), and vice versa (b, c). 3/6

Rifts shape Earth’s surface. Young rifts extend by faulting, but mature rifts extend by magmatic activity. Determining when efficient crustal magma delivery systems develop in intermediate-stage rifts (like the MER) can help constrain the seismic-to-magmatic transition. 2/6

Magmas move rapidly beneath the Main Ethiopian Rift (MER), suggesting that an efficient rift magmatic system has already developed despite its relative tectonic immaturity! New research in Nature Geoscience: doi.org/10.1038/s415... 1/6

Pleasure to participate today in Prof. Chen Zhu's geochemical modelling short course at @cambridge-earthsci.bsky.social !

...however, happy to say that I've rejoined Cambridge Earth Sciences as a postdoc for a short while, then off to Carnegie later this year!

A time of change for me! My tenure with @deep-carbon.bsky.social Unibo has ended, thanks to @avitaleb.bsky.social et al. for being fantastic hosts and colleagues! Sad to leave such a welcoming environment...

My friend in Edinburgh has let me know that they use my name badge from a PhD interview there 7 years ago as a festive decoration #Christmas
