5.1 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.
Hyaloclastite is a type of Igneous rock is formed through the cooling and solidification of lava or magma.
