Cubic zirconia in >2370◦C impact melt records Earth’s hottest crust

Bolide impacts influence primordial evolution of planetary bodies because they can cause instantaneous melting and vaporization of both crust and impactors. Temperatures reached by impact-generated silicate melts are unknown because meteorite impacts are e ...

Porosity evolution at the brittle-ductile transition in the continental crust: Implications for deep hydro-geothermal circulation

Marie Estelle Solange Violay, Mateo Alejandro Acosta, Michael Heap

Recently, projects have been proposed to engineer deep geothermal reservoirs in the ductile crust. To examine their feasibility, we performed high-temperature (up to 1000 degrees C), high-pressure (130 MPa) triaxial experiments on granite (initially-intact ...

From rock to magma and back again: The evolution of temperature and deformation mechanism in conduit margin zones

Marie Estelle Solange Violay, Michael Heap

Explosive silicic volcanism is driven by gas overpressure in systems that are inefficient at outgassing. The zone at the margin of a volcanic conduit-thought to play an important role in the outgassing of magma and therefore pore pressure changes and explo ...
