1.1 Definition

Latite is an igneous, volcanic rock, with aphanitic-aphyric to aphyric-porphyritic texture

Ignimbrite is a volcanic rock consisting mainly of pumice fragments, formed by the consolidation of material deposited by pyroclastic flows

5 Formation

5.1 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.

Ignimbrites are formed from very poorly sorted mixture of volcanic ash or tuff and pumice lapilli, commonly with scattered lithic fragments.

All about Latite and Ignimbrite Properties

Know all about Latite and Ignimbrite properties here. All properties of rocks are important as they define the type of rock and its application. Latite and Ignimbrite belong to Igneous Rocks.Texture of Latite is Aphanitic to Porphyritic whereas that of Ignimbrite is Aphanitic. Latite appears Rough and Ignimbrite appears Dull, Vesicular and Foilated. The luster of Latite is subvitreous to dull while that of Ignimbrite is vitreous to dull. Latite is available in black, brown, colourless, green, grey, pink, white colors whereas Ignimbrite is available in beige, black, brown, grey, pink, white 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 Ignimbrite are cemetery markers, commemorative tablets, creating artwork.
