1 Definition

1.1 Definition

Kimberlite is a rare, blue-tinged, coarse-grained intrusive igneous rock, which sometimes contains diamonds and is mostly found in South Africa and Siberia.

Argillites are highly compact sedimentary or slightly metamorphosed rocks that consist largely or wholly of particles of clay or silt but lack the fissility of shale or the cleavage characteristic of slate

1.2 History

1.2.1 Origin

Kimberley, South Africa

1.3 Etymology

From Kimberley +‎ -ite, from the name of the South African town of Kimberley where the rock was first found.

From Latin Argilla (clay) and -ite in English which became agrilla+ -ite = Argillite

5 Formation

5.1 Formation

Kimberlite is an igneous rock and is the main source of diamonds. Its formation takes place deep beneath the Earth’s surface between 150 to 450 kilometres, and are erupted rapidly and violently.

An argillite is a fine-grained sedimentary rock mainly composed of clay particles which forms from lithified muds which contain variable amounts of silt-sized particles.

All about Kimberlite and Argillite Properties

Know all about Kimberlite and Argillite properties here. All properties of rocks are important as they define the type of rock and its application. Kimberlite belongs to Igneous Rocks while Argillite belongs to Sedimentary Rocks.Texture of Kimberlite is Porphyritic whereas that of Argillite is Clastic, Polished. Kimberlite appears Dull and Banded and Argillite appears Rough and Dull. The luster of Kimberlite is subvitreous to dull while that of Argillite is waxy and dull. Kimberlite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors whereas Argillite is available in dark grey to black, pink, red, white colors. The commercial uses of Kimberlite are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux, production of lime, soil conditioner, source of magnesia (mgo) and that of Argillite are fire resistant, used to manufracture paperweights and bookends.
