Sample Description

This sample was collected from the intrusive basalt plug 6 km south of the western alteration center within the Cuprite Hills. The sample spectrum was of a slightly weathered surface. Most other surfaces in the intrusive body are heavily coated with desert varnish and hence have much weaker pyroxene absorptions.

XRD Analysis

Augite (major), diopside (major), anorthite (major), forsterite (trace), quartz (trace), analcime (trace).
