Formation

Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.

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 Scoria and Latite Properties

Know all about Scoria and Latite properties here. All properties of rocks are important as they define the type of rock and its application. Scoria and Latite belong to Igneous Rocks.Texture of Scoria is Vesicular whereas that of Latite is Aphanitic to Porphyritic. Scoria appears Glassy and Vesicular and Latite appears Rough. The luster of Scoria and Latite is subvitreous to dull. Scoria is available in black, brown, dark grey to black, red colors whereas Latite is available in black, brown, green, grey, pink, white colors. The commercial uses of Scoria are as a traction material on snow-covered roads, creating artwork, high-temperature insulation, in gas barbecue grills and that of Latite are an oil and gas reservoir, as a feed additive for livestock, metallurgical flux, soil conditioner, source of magnesia (mgo).
