Formation
Flint is formed by the decomposition and compaction of various organisms such as sponges and diatoms under the water.
Benmoreite is a type of Igneous rock which is formed through the cooling and solidification of lava or magma. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
