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

Features
Clasts are smooth to touch, Easily splits into thin plates, Has High structural resistance against erosion and climate
Clasts are smooth to touch, Is one of the oldest rock, Matrix variable
Archaeological Significance
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.

All about Flint and Conglomerate Properties
Know all about Flint and Conglomerate properties here. All properties of rocks are important as they define the type of rock and its application. Flint and Conglomerate belong to Sedimentary Rocks.Texture of Flint is Banded, Rough whereas that of Conglomerate is Clastic. Flint appears Glassy or Pearly and Conglomerate appears Shiny and Rounded. The luster of Flint is vitreous while that of Conglomerate is dull. Flint is available in black, brown, green, grey, red, white colors whereas Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors. The commercial uses of Flint are creating artwork, gemstone, in fire-starting tools, manufacture of tools, metallurgical flux, jewelry, to ignite fire, used in flintlock firearms and that of Conglomerate are cemetery markers, in aquifers, tombstones.
