5 Formation

5.1 Formation

Shonkinites are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.

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 Shonkinite and Dolomite Properties

Know all about Shonkinite and Dolomite properties here. All properties of rocks are important as they define the type of rock and its application. Shonkinite belongs to Igneous Rocks while Dolomite belongs to Sedimentary Rocks.Texture of Shonkinite is Earthy whereas that of Dolomite is Earthy. Shonkinite appears Banded and Foilated and Dolomite appears Glassy or Pearly. The luster of Shonkinite is subvitreous to dull while that of Dolomite is vitreous and pearly.
