Slaty cleavage texture

WebJul 16, 2024 · The combination of shale and metamorphism leads to a unique type of foliation known as slaty cleavage, which is a fancy way of saying that slate's surfaces break (cleavage) in a way that is unique ... 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?
