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