Physical properties
Hardness of 2-2.5 on Mohs scale, silvery-white to yellow color, pearly to metallic luster, foliated crystal structure with pronounced cleavage.
Formation & geological history
Formed through regional metamorphism of argillaceous sedimentary rocks under moderate to high temperatures and pressures.
Uses & applications
Used in the manufacturing of paints, joint cements, and as a filler in plastics and rubber industries.
Geological facts
Schist is characterized by its distinct foliation, allowing it to split easily into thin flakes due to the alignment of mica minerals.
Field identification & locations
Identified easily by its shiny, reflective flakes on surfaces; commonly found in regional metamorphic terranes worldwide.
