Abstract

Grossular garnet has been observed in several white inclusions in the Allende meteorite. Compositions range from Gro9sPy5 to Gro88Py12 in five inclusions. Its mottled appearance indicates that it crystallized from a glass of near‐grossular composition and not by a solid state reaction between wollastonite, anorthite and melilite. These grossular‐bearing inclusions either condensed directly as metastable liquids from the solar nebula or if initial solid condensates were liquefied by some subsequent heating process. In either case, a prolonged residence time in a thermal blanket appears necessary to effect crystallization of the grossular.
