5 Formation
5.1 Formation
Amphibolite is a coarse-grained metamorphic rock which forms by metamorphism of mafic igneous rocks like basalt and gabbro or from the metamorphism of clay-rich sedimentary rocks like marl or graywacke.
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 Amphibolite and Dolomite Properties

Know all about Amphibolite and Dolomite properties here. All properties of rocks are important as they define the type of rock and its application. Amphibolite belongs to Metamorphic Rocks while Dolomite belongs to Sedimentary Rocks.Texture of Amphibolite is Banded, Foliated, Massive whereas that of Dolomite is Earthy. Amphibolite appears Foliated and Dolomite appears Glassy or Pearly. The luster of Amphibolite is vitreous to dull while that of Dolomite is vitreous and pearly. Amphibolite is available in black, brown, green, grey colors whereas Dolomite is available in black, brown, colourless, green, grey, pink, white colors. The commercial uses of Amphibolite are cemetery markers, commemorative tablets, creating artwork 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).
