Thin Section Thursday! contributed by Reagan Elizabeth Davis, UG student at James Madison University. The rock pictured is a Kyanite Quartzite gathered near Ogilby California. (XPL) Kyanite shows low to moderate interference colors, and bladed form. #ThinSectionThursday #kyanite

T.S. Thursday: 2.8 Ga Granodiorite from the Beartooth Mtns, MT in crossed polars and cathodoluminescence. In CL the red zone between microcline and plagioclase is a fine-grained myrmekite (plagioclase and quartz intergrowths). Contributed by Darrell Henry. #thinsectionthursday
