Definition
Enderbite rock is an igneous rock which belongs to the Charnockite rock series
Gneiss is a common and widely distributed type of rock formed by high-grade regional metamorphic processes from pre-existing formations that were originally either igneous or sedimentary rocks

Formation
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.
Gneiss is a high grade metamorphic rock i.e. it has been subjected to higher temperatures and pressures than schist. It is formed by the metamorphosis of Gneiss forms from volcanic rock, shale or granitie.
