Formation
Flint is formed by the decomposition and compaction of various organisms such as sponges and diatoms under the water.
Theralite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
