Definition
Websterite is ultramafic and ultrabasic rock that consists of roughly equal proportions of orthopyroxene and clinopyroxene. It is a special type of pyroxenite.
Flint is a hard type of sedimentary rock that produces a small piece of burning material when hit by steel

Formation
Websterite can be formed as cumulates in ultramafic intrusions by accumulation of pyroxene crystals at the base of the lava chamber.
Flint is formed by the decomposition and compaction of various organisms such as sponges and diatoms under the water.
