Definition

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

Skarns are formed during regional or contact metamorphism and from a variety of metasomatic processes involving fluids of magmatic, metamorphic, and/or marine origin

Formation

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

Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Skarn is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.
