Item

Title

RR1: Metamorphic Contact

Description

A small rock drill core from the metamorphic contact between the diabase and base rock of red siltstone. The sample is fine-grained and dark colored indicating mostly mafic minerals. The thin section consists of a dark very fine grained matrix with mostly hypidioblastic quartz porphyroblasts. There is surprisingly no banding. There is one piece of sillimanite indicating high metamorphic grade. There are also some poikiloblasts. Location 40.5621 N, 75.1261 W.
