Abstract

Orthopyroxene (En85) weathers initially by vacancy diffusion, and through this process hydration occurs and a sequence of biopyriboles develops, culminating in a talc-like layer silicate whose structure joins coherently to the orthopyroxene structure. Oxidation of Fe2+ to Fe3+ colors the altering pyroxene yellow. The complete conversion of orthopyroxene to talc plus oxides takes place through three sequential mineral reactions without the development of the noncrystalline phase. -from Authors
