5 Formation

5.1 Formation

Anorthosite is a phaneritic, intrusive igneous rock which is characterized by a predominance of plagioclase feldspar which is almost 90–100%, and a minimal mafic component.

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