10 Formation

10.1 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.

Gabbro, a mafic rock, forms due to cooling and crystallization of magma underneath Earth's surface.
