Slaty texture

WebAug 20, 2024 · Slaty cleavage is a pervasive, parallel foliation (layering) of fine-grained platy minerals (chlorite) in a direction perpendicular to the direction of maximum stress. The process produces the rocks slate and phyllite. They represent slaty cleavage, developed when the rock was compressed and folded. What group of minerals define schistosity?
