Chromium-silicates, Feldspars and Highly Silicic Glasses Formed from Felsic Melts in Post-depressurization Ferroan Ureilites, Especially


Depressurization is the dominant process that produces mantle melts on Earth. Depressurization had equally profound but quite different effects in the evolution of ureilite meteorites. The second most abundant type of achondrite, ureilites formed as anatectic restites (olivine + pyroxene + minor, 0.2-6 wt%, carbon) in the mantle(s) of carbonaceous asteroid… (More)
