Lamprophyre and Claystone
Definition
Definition
Lamprophyre is uncommon igneous rocks primarily occurring as dikes, lopoliths, laccoliths, stocks and small intrusions
Claystone is a fine-grained, dark gray to pink sedimentary rock which mainly consists of compacted and hardened clay

Formation
Formation
Lamprophyre formation takes place deep beneath the Earth’s surface at around 150 to 450 kilometres, and are erupted rapidly and violently.
Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.

All about Lamprophyre and Claystone Properties
Know all about Lamprophyre and Claystone properties here. All properties of rocks are important as they define the type of rock and its application. Lamprophyre belongs to Igneous Rocks while Claystone belongs to Sedimentary Rocks.Texture of Lamprophyre is Porphyritic whereas that of Claystone is Clastic. Lamprophyre appears Dull, Banded and Foilated and Claystone appears Rough and Dull. The luster of Lamprophyre is subvitreous to dull while that of Claystone is dull. Lamprophyre is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors whereas Claystone is available in black, blue, brown, green, grey, orange, red, white, yellow 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 Claystone are pottery.
