How does slate form from shale
WebThe boundary between slate and shale may be poorly defined as slate is the weakly metamorphosed equivalent of shale. Main Minerals: clay minerals, quartz, all very small. Weathering Behavior: Small particle size favors chemical weathering, well developed cleavage planes are susceptible to physical weathering (e.g., due to frost wedging). WebJul 7, 2024 · To become schist, a shale must be metamorphosed in steps through slate and then through phyllite. If the schist is metamorphosed further, it might become a granular rock known as gneiss. ….
