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.
Dacitic magma is formed by the subduction of young oceanic crust under a thick felsic continental plate. Further, the Oceanic crust is hydrothermally altered as quartz and sodium are added.

All about Latite and Dacite Properties
Know all about Latite and Dacite properties here. All properties of rocks are important as they define the type of rock and its application. Latite and Dacite belong to Igneous Rocks.Texture of Latite is Aphanitic to Porphyritic whereas that of Dacite is Aphanitic to Porphyritic. Latite appears Rough and Dacite appears Vesicular. The luster of Latite and Dacite is subvitreous to dull. Latite is available in black, brown, colourless, green, grey, pink, white colors whereas Dacite is available in bluish - grey, brown, grey, light to dark 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 Dacite are commemorative tablets, creating artwork.
