Formation
Latite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
Flint is formed by the decomposition and compaction of various organisms such as sponges and diatoms under the water.

All about Latite and Flint Properties
Know all about Latite and Flint properties here. All properties of rocks are important as they define the type of rock and its application. Latite belongs to Igneous Rocks while Flint belongs to Sedimentary Rocks.Texture of Latite is Aphanitic to Porphyritic whereas that of Flint is Banded, Rough. Latite appears Rough and Flint appears Glassy or Pearly. The luster of Latite is subvitreous to dull while that of Flint is vitreous. Latite is available in black, brown, colourless, green, grey, pink, white colors whereas Flint is available in black, brown, green, grey, red, white colors. The commercial uses of Latite are an oil and gas reservoir, as a feed additive for livestock, metallurgical flux, soil conditioner, source of magnesia (mgo) and that of Flint are creating artwork, gemstone, in fire-starting tools, manufacture of tools, metallurgical flux, jewelry, to ignite fire, used in flintlock firearms.
