Description
Schistose foliation composed of well intermixed quartz, feldspar, and muscovite (with biotite and possible amphibole).Schists have quartz and feldspar intermixed with a mica mineral, either muscovite or biotite, or both. In this specimen, and unlike specimen #1 muscovite dominates, giving it its light color. Often other minerals are present too, such as garnet and staurolite, but none are present in this particular specimen. |

Tectonic Association
Schists are typically associated with major mountain building events when shales or clay rich sandstones (wackes) are metamorphosed through depth of burial, and proximity to batholiths (click picture for larger version).
