Definition
Diamictite is a sedimentary rock that consists of non-sorted to poorly sorted terrigenous sediment containing particles that range in size from clay to boulders, suspended in a matrix of mudstone or sandstone
Flint is a hard type of sedimentary rock that produces a small piece of burning material when hit by steel

Formation
Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.
Flint is formed by the decomposition and compaction of various organisms such as sponges and diatoms under the water.
