The ferroan anorthosite suite is the most common group in the highlands, and is inferred to symbolize plagioclase flotation cumulates from the lunar magma ocean, with interstitial mafic phases fashioned from trapped interstitial soften or rafted upwards Together with the far more considerable plagioclase framework.
