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.

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

All about Latite and Dolomite Properties

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