Definition

Enderbite rock is an igneous rock which belongs to the Charnockite rock series

Slate is a fine-grained, foliated, homogeneous metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash through low-grade regional metamorphism

Formation

Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.

Slate is a low grade metamorphic rock that is generally formed by metamorphosis of mudstone or shale, under relatively low pressure and temperature conditions.
