Formation
Greenschist is medium grade metamorphic rock, formed by the metamorphosis of mudstone or shale, or some types of igneous rock, when it is subjected to higher temperatures and pressures.
Flint is formed by the decomposition and compaction of various organisms such as sponges and diatoms under the water.
