Experimentally reproduced textures and mineral chemistry of Apollo 15 quartz normative basalts

Abstract

An analog of the Apollo 15 quartz-normative basalts (also called pyroxene-phyric basalts) has been experimentally crystallized at a variety of linear cooling rates between 1250 and 1°C/hr at one atmosphere total pressure and oxygen fugacities close to those ascribed to lunar rocks.
