Etymology
From Old English flint - a type of rock mainly known for high hardness and for giving off sparks when struck
From the Lherz Massif, an alpine peridotite complex, at Étang de Lers, near Massat in the French Pyrenees; Lherz is the archaic spelling of this location

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