Definition
Flint is a hard type of sedimentary rock that produces a small piece of burning material when hit by steel
A hydration and metamorphic transformation of ultramafic rock from the Earth's mantle is called as serpentinization, a group of minerals is formed by serpentinization compose rock 'serpentinite'.

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. Serpentinite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

All about Flint and Serpentinite Properties
Know all about Flint and Serpentinite properties here. All properties of rocks are important as they define the type of rock and its application. Flint belongs to Sedimentary Rocks while Serpentinite belongs to Metamorphic Rocks.Texture of Flint is Banded, Rough whereas that of Serpentinite is Earthy. Flint appears Glassy or Pearly and Serpentinite appears Rough and Dull. The luster of Flint is vitreous while that of Serpentinite is waxy and dull. Flint is available in black, brown, green, grey, red, white colors whereas Serpentinite is available in black, brown, colourless, green, grey, white 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 Serpentinite are commemorative tablets, creating artwork.
