A series of new #experiments is conducted by Natalia Nevskaya (CH/US) to understand the #nucleation of #polymineralic #shearzones and shows weak behavior due to the activation of diss–precip. #creep:

Katherine Billings (US) conducts #deformationexperiments to understand the #evolution of #mica layers to #ultramylonitic microstructures in #shearzones, from mica grain size reduction to #phasemixing. Check it out:

ultra-thin section of marble

#ThinSectionThursday My PhD supervisor, Giovanni Musumeci, used these STUNNING ultra- #thinsections of #marble to document #shearzones in the Elba contact aureoles

I am in love. Gonna take a lot of pics when I have time ❤️
