Flint is a hard type of sedimentary rock that produces a small piece of burning material when hit by steel
Slate is a fine-grained, foliated, homogeneous metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash through low-grade regional metamorphism

5.1 Formation
Flint is formed by the decomposition and compaction of various organisms such as sponges and diatoms under the water.
Slate is a low grade metamorphic rock that is generally formed by metamorphosis of mudstone or shale, under relatively low pressure and temperature conditions.
