This is a #serpentinite #shearzone.
It is part of a #subduction complex where oceanic serpentinites were subducted, sheared, carbonated, exhumed, and coupled with sediments that we recently described on the Island of Elba, Italy. A 3ad

Happy International Day of Women and Girls in Science!
My journey has brought me so much. Fossil prep, museums, field work, travel, my first research publication, museum collections, connections, and of course, some of the best friendships I've ever had.
Keep that dream going!

At some point in life I became a geologist, but I sometimes ask myself 'how would it be like to have chosen a different major?'
Gladly, I have recently had the opportunity to try the 'naturalist' life! Here is a preprint of my spider paper that's under review 😍

Sigmoidal structures (S-C structures) developed in deformed limestones within the Tellare fault. What's remarkable is the presence of white tensional veins (white) oblique to shear planes and parallel to the [theoretical] sigma 1.

Incredible rock! A retrogressed eclogite in which amazing simplectites developed during amphibolite-facies metamorphism. Garnet is surrounded by coronas of plagioclase and hornblende. Omphacite is replaced by diopside + plagioclase simplectites. ❤️
