Definition

Carbonatite is intrusive or extrusive igneous rock which is defined by mineralogic composition, consisting of greater than 50 percent carbonate minerals

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

Formation

Carbonatites are intrusive or extrusive igneous rocks which are defined by mineralogic composition consisting of greater than 50 percent carbonate minerals and are formed due to low degrees of partial melting of rocks.

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.

All about Carbonatite and Wehrlite Properties

Know all about Carbonatite and Wehrlite properties here. All properties of rocks are important as they define the type of rock and its application. Carbonatite and Wehrlite belong to Igneous Rocks.Texture of Carbonatite is Granular, Poikiloblastic whereas that of Wehrlite is Banded. Carbonatite appears Dull, Banded and Foilated and Wehrlite appears Rough and Banded. The luster of Carbonatite is subvitreous to dull while that of Wehrlite is metallic. Carbonatite is available in black, brown, green, grey, pink, white colors whereas Wehrlite is available in dark greenish - grey, green colors. The commercial uses of Carbonatite are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux and that of Wehrlite are cemetery markers, creating artwork, gemstone, jewelry.
