Origin of quartz in basaltic eucrite

Abstract

We have been investigating silica minerals in eucrites to understand their petrogenetic history. We found quartz in the four eucrite using cathodoluminescence (CL) technique. We carried out petrologic chemical, Raman and CL analysis to clarify the origin of quartz in four eucrite. The results imply that the quartz grains in the eucrites formed by hydrothermal alteration.
