Abstract

Data is presented on textural variation, optical properties, and resultant compositions of the olivines from a differentiated teschenite sill. The range in olivine composition is from Fa21 to Fa,60. Both the individual crystals and successive crops of crystals become more fayalitic with progressive differentiation.
