资源简介：
Structural formulae computed on the basis of 6(O). Orthopyroxenes are microphenocrysts or parts of two-pyroxene intergrowths. 49 and 54 may show effects of partial overlap of the probe beam with glass and clinopyroxene. Clinopyroxene Analyses 50, 58, 70, 71, and 74 are of rims of bronzite. All others are cores to larger microphrenocrysts or grains in two-pyroxene intergrowths.
