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

This work was supported by UKRI NERC Leeds-York DTP SPHERES, and concludes the research performed during my PhD. A big thank you to all the coauthors and collaborators who helped me tackle basaltic volcanism in the Ethiopian Rift! 6/6

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
Figure 6 of Wong et al., comparing the times from olivine diffusion chronometry in the Main Ethiopian Rift to magmatic rift intrusion intervals recorded geophysically at other rift systems.

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
Figure 5 of Wong et al., showing a schematic diagram for magma movement in the Main Ethiopian Rift crust.

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
Figure 3 of Wong et al., illustrating compositional zones in olivine and diffusional model fits to those zones.

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 !
Participants of the short course stood on the Sedgwick Museum stairs.

...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
