Formation
Essexite is a type of igneous rock, which is usually dark grey to black plutonic rock. For the formation of essexite, suitable magma with exact composition of K, Ba, Rb, Cs, Sr should be produced.
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.
