5 Formation

5.1 Formation

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

Dacitic magma is formed by the subduction of young oceanic crust under a thick felsic continental plate. Further, the Oceanic crust is hydrothermally altered as quartz and sodium are added.

More about Dolomite and Dacite

Here you can know more about Dolomite and Dacite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Dolomite and Dacite consists of mineral content and compound content. The mineral content of Dolomite includes Clay Minerals, Pyrite, Quartz, Sulfides and mineral content of Dacite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Magnetite, Plagioclase, Pyroxene, Quartz, Zircon. You can also check out the list of all Sedimentary Rocks. When we have to compare Dolomite vs Dacite, the texture, color and appearance plays an important role in determining the type of rock. Dolomite is available in black, brown, colourless, green, grey, pink, white colors whereas, Dacite is available in bluish - grey, brown, grey, light to dark grey colors. Appearance of Dolomite is Glassy or Pearly and that of Dacite is Vesicular. Properties of rock is another aspect for Dolomite vs Dacite. The hardness of Dolomite is 3.5-4 and that of Dacite is 2-2.25. The types of Dolomite are Boninite and Jasperoid whereas types of Dacite are Footwall Dacite, Hanging wall Dacite, Tuff and Biotite Dacite.
