Archaeological Significance
Formation
Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.
Benmoreite is a type of Igneous rock which is formed through the cooling and solidification of lava or magma. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
