Formation
Latite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
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.

All about Latite and Taconite Properties
Know all about Latite and Taconite properties here. All properties of rocks are important as they define the type of rock and its application. Latite belongs to Igneous Rocks while Taconite belongs to Sedimentary Rocks.Texture of Latite is Aphanitic to Porphyritic whereas that of Taconite is Banded, Trellis. Latite appears Rough and Taconite appears Layered, Banded, Veined and Shiny. The luster of Latite is subvitreous to dull while that of Taconite is earthy. Latite is available in black, brown, colourless, green, grey, pink, white colors whereas Taconite is available in red, reddish brown colors. The commercial uses of Latite are an oil and gas reservoir, as a feed additive for livestock, metallurgical flux, soil conditioner, source of magnesia (mgo) and that of Taconite are as a touchstone, cemetery markers, creating artwork.
