Definition

Wehrlite is an ultramafic and ultrabasic rock that is a mixture of olivine and clinopyroxene. It is a subdivision of the peridotites

Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight

Formation

Wehrlite 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.

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 Wehrlite and Dolomite Properties

Know all about Wehrlite and Dolomite properties here. All properties of rocks are important as they define the type of rock and its application. Wehrlite belongs to Igneous Rocks while Dolomite belongs to Sedimentary Rocks.Texture of Wehrlite is Banded whereas that of Dolomite is Earthy. Wehrlite appears Rough and Banded and Dolomite appears Glassy or Pearly. The luster of Wehrlite is metallic while that of Dolomite is vitreous and pearly. Wehrlite is available in dark greenish - grey, green colors whereas Dolomite is available in black, brown, green, grey, pink, white colors. The commercial uses of Wehrlite are cemetery markers, creating artwork, gemstone, jewelry 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).
