Formation

Granodiorite is an intrusive igneous rock which is very hard, crystalline and is visibly homogeneous in texture and forms by melting of continental 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 Granodiorite and Dolomite Properties

Know all about Granodiorite and Dolomite properties here. All properties of rocks are important as they define the type of rock and its application. Granodiorite belongs to Igneous Rocks while Dolomite belongs to Sedimentary Rocks.Texture of Granodiorite is Granular, Phaneritic whereas that of Dolomite is Earthy. Granodiorite appears Veined or Pebbled and Dolomite appears Glassy or Pearly. The luster of Granodiorite is grainy, pearly and vitreous while that of Dolomite is vitreous and pearly. Granodiorite is available in black, grey, orange, pink, white colors whereas Dolomite is available in black, brown, green, grey, pink, white colors.
