Definition
Flint is a hard type of sedimentary rock that produces a small piece of burning material when hit by steel
  
Metapelite is an old and currently not widely used field geological term for a clay rich fine-grained clastic sediment or sedimentary rock, i.e. mud or a mudstone

Formation
Flint is formed by the decomposition and compaction of various organisms such as sponges and diatoms under the water.
  
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Metapelite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.
