Definition
Flint is a hard type of sedimentary rock that produces a small piece of burning material when hit by steel
Wehrlite is an ultramafic and ultrabasic rock that is a mixture of olivine and clinopyroxene. It is a subdivision of the peridotites

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