Abstract

The majority of this thin section is a mosaic of inequigranular, anhedral hornblende and highly-poikilitic k-feldspar. Though a few large, irregularly shaped masses of prehnite are interspersed amidst the hornblende and k-feldspar, most prehnite is concentrated along a single vein that runs the length of the thin section. Some of the prehnite shows anomalous blue extinction.
