Definition

Flint is a hard type of sedimentary rock that produces a small piece of burning material when hit by steel

Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix

Etymology

From Old English flint - a type of rock mainly known for high hardness and for giving off sparks when struck

From Latin conglomeratus, to roll together, i.e. from com together + glomerare to gather into a ball, from glomus (genitive glomeris) a ball

Formation

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

Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.
