Wehrlite and Limestone
Definition
Definition
Wehrlite is an ultramafic and ultrabasic rock that is a mixture of olivine and clinopyroxene. It is a subdivision of the peridotites
Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate

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.
Limestone is a sedimentary rock which is mainly made up of calcium carbonate.

All about Wehrlite and Limestone Properties
Know all about Wehrlite and Limestone properties here. All properties of rocks are important as they define the type of rock and its application. Wehrlite belongs to Igneous Rocks while Limestone belongs to Sedimentary Rocks.Texture of Wehrlite is Banded whereas that of Limestone is Clastic or Non-Clastic. Wehrlite appears Rough and Banded and Limestone appears Rough and Banded. The luster of Wehrlite is metallic while that of Limestone is dull to pearly. Wehrlite is available in dark greenish - grey, green colors whereas Limestone is available in beige, black, blue, brown, cream, gold, green, grey, light green, light grey, linen, pink, red, rust, silver, white, yellow colors. The commercial uses of Wehrlite are cemetery markers, creating artwork, gemstone, jewelry and that of Limestone are animal feed filler, as a feed additive for livestock, paper industry, raw material for manufacture of quicklime, slaked lime, soil conditioner, used in aquariums, whiting material in toothpaste, paint and paper.
