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