5 Formation

5.1 Formation

Shale forms when very fine-grained clay particles are deposited in water which settle at the bottom of water bodies. They are later compacted hence forming shale.

Andesite is a fine-grained igneous rock that forms when the magma is erupted onto the surface and is crystallized quickly.
