Formation
Flint is formed by the decomposition and compaction of various organisms such as sponges and diatoms under the water.
Suevite is a metamorphic rock consisting partly of melted material, typically forming a breccia containing glass and crystal or lithic fragments, formed during an impact event.

All about Flint and Suevite Properties
Know all about Flint and Suevite properties here. All properties of rocks are important as they define the type of rock and its application. Flint belongs to Sedimentary Rocks while Suevite belongs to Metamorphic Rocks.Texture of Flint is Banded, Rough whereas that of Suevite is Earthy. Flint appears Glassy or Pearly and Suevite appears Banded. The luster of Flint is vitreous while that of Suevite is earthy. Flint is available in black, brown, green, grey, red, white colors whereas Suevite is available in black, brown, colourless, green, grey, pink 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 Suevite are as a feed additive for livestock, gemstone, metallurgical flux, source of magnesia (mgo).
