"The variolitic texture suggests rapid cooling of magma, which is common for "quenched" angrites." A “Quenched angrite is a rapidly cooled magma preserving the original state of primary igneous crystallization at 4563-4564 Ma" see: MINERALOGY AND PETROLOGY OF NWA 7203: A NEW QUENCHED ANGRITE SIMILAR TO NWA 1296 AND NWA 1670.
