Definition

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

Troctolite is a mafic intrusive rock type. It consists essentially of major but variable amounts of olivine and calcic plagioclase along with minor pyroxene. It is an olivine-rich anorthosite, or a pyroxene-depleted relative of gabbro

Formation

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

Troctolite 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.
