5 Formation

5.1 Formation

Nephelinite 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.

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.

All about Nephelinite and Latite Properties

Know all about Nephelinite and Latite properties here. All properties of rocks are important as they define the type of rock and its application. Nephelinite and Latite belong to Igneous Rocks.Texture of Nephelinite is Aphanitic whereas that of Latite is Aphanitic to Porphyritic. Nephelinite appears Skeletal and Latite appears Rough. The luster of Nephelinite is vitreous to metallic while that of Latite is subvitreous to dull. Nephelinite is available in black, brown, colourless, green, grey, white colors whereas Latite is available in black, brown, colourless, green, grey, pink, white colors. The commercial uses of Nephelinite are creating artwork, soil conditioner, source of magnesia (mgo) and that of Latite are an oil and gas reservoir, as a feed additive for livestock, metallurgical flux, soil conditioner, source of magnesia (mgo).
