Physical properties
Medium to coarse-grained, strongly foliated (schistosity), visible mica flakes, often gray to greenish-gray depending on chlorite or mica content, Mohs hardness variable depending on constituent minerals.
Formation & geological history
Formed by regional metamorphism of shale, mudstone, or some types of igneous rocks under medium temperature and pressure conditions.
Uses & applications
Often used as a building stone, decorative stone, and in landscaping. Sometimes studied by geologists to understand metamorphic history.
Geological facts
Schistosity allows the rock to be split easily into thin flakes or plates. Greenish varieties often contain chlorite.
Field identification & locations
Identified by its pronounced foliation (schistosity) and visible, sparkling mica crystals. Found worldwide in mountain belts.
