Formation

Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.

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.
