Formation
Formation
Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.
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.

All about Dolomite and Latite Properties
Know all about Dolomite and Latite properties here. All properties of rocks are important as they define the type of rock and its application. Dolomite belongs to Sedimentary Rocks while Latite belongs to Igneous Rocks.Texture of Dolomite is Earthy whereas that of Latite is Aphanitic to Porphyritic. Dolomite appears Glassy or Pearly and Latite appears Rough. The luster of Dolomite is vitreous and pearly while that of Latite is subvitreous to dull. Dolomite and Latite are available in black, brown, colourless, green, grey, pink, white colors. The commercial uses of Dolomite and Latite are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux, production of lime, soil conditioner, source of magnesia (mgo).
