5 Formation

5.1 Formation

Lamprophyre formation takes place deep beneath the Earth’s surface at around 150 to 450 kilometres, and are erupted rapidly and violently.

Blueschist forms due to the metamorphism of basalt and other rocks with similar composition at high pressures and low temperatures and approximately corresponding to a depth of 15 to 30 kilometers and 200 to 500 °C.

All about Lamprophyre and Blueschist Properties

Know all about Lamprophyre and Blueschist properties here. All properties of rocks are important as they define the type of rock and its application. Lamprophyre belongs to Igneous Rocks while Blueschist belongs to Metamorphic Rocks.Texture of Lamprophyre is Porphyritic whereas that of Blueschist is Foliated. Lamprophyre appears Dull, Banded and Foilated and Blueschist appears Dull and Banded. The luster of Lamprophyre is subvitreous to dull while that of Blueschist is dull. Lamprophyre is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors whereas Blueschist is available in blue, bluish - grey, purple, shades of blue colors. The commercial uses of Lamprophyre 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 Blueschist are cemetery markers, commemorative tablets, creating artwork, curling, tombstones.
