Definition

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

Felsite is a very fine grained volcanic rock that may or may not contain larger crystals and light colored rock that typically requires petrographic examination or chemical analysis for more precise definition

Formation

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

Felsite 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.
