Shale is a fine-grained sedimentary rock which is formed by the compaction of silt and clay-size mineral particles

Johann Gottlob Lehmann

From German Schalstein laminated limestone, and Schalgebirge layer of stone in stratified rock. From Old English scealu in its base sense of- thing that divides or separate,
