Shale

Slate is a microcrystalline metamorphic rock, most often derived from shale and composed mostly of micas and quartz. The micaceous minerals have a subparallel orientation (foliation) which imparts strong cleavage to the rock, thus allowing the rock to be split into thin but tough sheets (ASTM 1998). Shale is a fine-grained laminated sedimentary ...
