Amphibole (actinolite) in epidote, chlorite, garnet calcsilicate rock

NS-9

Macroscopic: Porphyroblastic amphibole in epidote, chlorite, and garnet calcsilicate rock. This sample represent the metamorphism of calcarious concretions in beds of quartzite to a schist. The formation this samples comes from has considerable mineralogical variation yielding some garnet rich and some epidote rich zones. The hand sample has a mineral zone consisting of garnets. Microscopic: Large amphibole phenocryst observed as well as quartz and chlorite. Thin section pictures in XPL unless otherwise noted in the title of the picuture. Thin sections are 3mm across.
