Trachyte and Kimberlite

1 Definition
1.1 Definition
Trachyte is a grey fine-grained volcanic rock which mainly consists of alkali feldspar
Kimberlite is a rare, blue-tinged, coarse-grained intrusive igneous rock, which sometimes contains diamonds and is mostly found in South Africa and Siberia.

5 Formation
5.1 Formation
Trachyte is an igneous volcanic rock with an aphanitic to porphyritic texture. It is the volcanic equivalent of syenite rock and forms as a result of magmatic differentiation.
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.

All about Trachyte and Kimberlite Properties

Know all about Trachyte and Kimberlite properties here. All properties of rocks are important as they define the type of rock and its application. Trachyte and Kimberlite belong to Igneous Rocks.Texture of Trachyte is Aphanitic to Porphyritic whereas that of Kimberlite is Porphyritic. Trachyte appears Banded and Kimberlite appears Dull and Banded. The luster of Trachyte is metallic while that of Kimberlite is subvitreous to dull. Trachyte is available in black, brown, dark greenish - grey, green, grey, light to dark grey, white colors whereas Kimberlite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors. The commercial uses of Trachyte are cemetery markers, creating artwork and that 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).
