Uses of Slate Rock
The multi-layered slate stone is formed from the metamorphosis of shale (a soft claystone). When shale is subjected to high temperatures and pressure, it flattens out to form slate. The mineral composition of slate includes pyrite, chlorite, biotite,...
Slate is a fine-grained, foliated, homogeneous metamorphic rock derived from an
original shale-type sedimentary rock composed of clay or volcanic ash through ...
Slate is a foliated metamorphic rock that forms from the metamorphism of shale.

Slates are metamorphic rocks, most of which began as clay sediments deposited
by water. The age of slates varies somewhat, but many were formed among old ...
