Definition
Latite is an igneous, volcanic rock, with aphanitic-aphyric to aphyric-porphyritic texture
Gneiss is a common and widely distributed type of rock formed by high-grade regional metamorphic processes from pre-existing formations that were originally either igneous or sedimentary rocks

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.
Gneiss is a high grade metamorphic rock i.e. it has been subjected to higher temperatures and pressures than schist. It is formed by the metamorphosis of Gneiss forms from volcanic rock, shale or granitie.

All about Latite and Gneiss Properties
Know all about Latite and Gneiss properties here. All properties of rocks are important as they define the type of rock and its application. Latite belongs to Igneous Rocks while Gneiss belongs to Metamorphic Rocks.Texture of Latite is Aphanitic to Porphyritic whereas that of Gneiss is Banded, Foliated, Platy. Latite appears Rough and Gneiss appears Foliated. The luster of Latite is subvitreous to dull while that of Gneiss is dull. Latite is available in black, brown, green, grey, pink, white colors whereas Gneiss is available in black, brown, pink, red, 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 Gneiss are cemetery markers, jewelry, tombstones, used in aquariums.
