Formation

Formation
Flint is formed by the decomposition and compaction of various organisms such as sponges and diatoms under the water.   
Alkali fledspar granite is an intrusive igneous rock which is very hard, crystalline and is visibly homogeneous in texture and forms by melting of continental rocks.
