Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight
Pantellerite is a peralkaline rhyolite. It has a higher iron and lower aluminium composition than comendite

Formation
Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.
Pantellerite 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 Pantellerite Properties
Know all about Dolomite and Pantellerite properties here. All properties of rocks are important as they define the type of rock and its application. Dolomite belongs to Sedimentary Rocks while Pantellerite belongs to Igneous Rocks.Texture of Dolomite is Earthy whereas that of Pantellerite is Eutaxitic. Dolomite appears Glassy or Pearly and Pantellerite appears Layered and Foliated. The luster of Dolomite is vitreous and pearly while that of Pantellerite is earthy. Dolomite is available in black, brown, colourless, green, grey, pink, white colors whereas Pantellerite is available in dark greenish - grey colors. The commercial uses 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) and that of Pantellerite are creating artwork.
