We are pleased to welcome Sarah T. Stewart to talk at a Petrology Lunch, on the topic of: Exploring the SiO2 system with shock waves.
Abstract:
Shock compression can explore regions of the phase diagram that are inaccessible by static techniques. Shock temperature measurements of fused silica and alpha-quartz have been interpreted to overshoot the equilibrium melt curve due to the kinetics of melting. Here, I will summarize the available shock data, kinetic processes, and a new reconciliation between static and shock determinations of the melt curve.
