5 Formation
5.1 Formation
Diorite is a coarse-grained intrusive igneous rock which contains large interlocking and randomly oriented crystals and forms when molten lava does not reach the Earth’s surface and cools down in the Earth’s crust.
Chalk is formed from lime mud, which accumulates on the sea floor which is then transformed into rock by geological processes.
