Title
2015-CTP-14: Metamorphic Rock Lab
Description
This rock was found from the counter top company in Easton, PA. The structure of the rock depicts likely low to intermediate grade metamorphism. Inclusions of biotite describe a likely regional metamorphism at lower to intermediate grades. Other possible inclusions of chlorite also indicate probable low grades of metamorphism. Inclusions of plagioclase crystals and quartz are also visible but do not support in determining a specific grade or setting of metamorphism. Due to the sample being taken from the counter top company, an origin of the sample is unable to be determined.
