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.

Pumice rock forms when the magma cools so quickly that atoms in the melt are not able to arrange themselves into a crystalline structure.

All about Latite and Pumice Properties

Know all about Latite and Pumice properties here. All properties of rocks are important as they define the type of rock and its application. Latite and Pumice belong to Igneous Rocks.Texture of Latite is Aphanitic to Porphyritic whereas that of Pumice is Vesicular. Latite appears Rough and Pumice appears Vesicular. The luster of Latite is subvitreous to dull while that of Pumice is earthy. Latite is available in black, brown, green, grey, pink, white colors whereas Pumice is available in beige, grey, light green, light grey, pink, white, yellow- grey 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 Pumice are as a traction material on snow-covered roads, as an abrasive in pencil erasers, fine abrasive used for polishing, manufacture of soap, solvents, dyes, plastics and fibres, used in aquariums.
