Formation

Formation
Taconite is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. When the river reaches a lake or sea, its load of transported rocks settles or deposits at the bottom of sea or lake.   
Lamprophyre formation takes place deep beneath the Earth’s surface at around 150 to 450 kilometres, and are erupted rapidly and violently.

All about Taconite and Lamprophyre Properties

Know all about Taconite and Lamprophyre properties here. All properties of rocks are important as they define the type of rock and its application. Taconite belongs to Sedimentary Rocks while Lamprophyre belongs to Igneous Rocks.Texture of Taconite is Banded, Trellis whereas that of Lamprophyre is Porphyritic. Taconite appears Layered, Banded, Veined and Shiny and Lamprophyre appears Dull, Banded and Foilated. The luster of Taconite is earthy while that of Lamprophyre is subvitreous to dull. Taconite is available in red, reddish brown colors whereas Lamprophyre is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors. The commercial uses of Taconite are as a touchstone, cemetery markers, creating artwork and that 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).
