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.
Flint is formed by the decomposition and compaction of various organisms such as sponges and diatoms under the water.
