Definition

Greenschist is a metamorphic rock that is formed under lowest temperatures and pressures and is usually produced by regional metamorphism

Flint is a hard type of sedimentary rock that produces a small piece of burning material when hit by steel

History

Origin

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.
