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

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.
Arkose rock forms from the weathering of feldspar-rich igneous or metamorphic rock, most commonly granitic rocks, which are primarily composed of quartz and feldspar.

All about Latite and Arkose Properties
Know all about Latite and Arkose properties here. All properties of rocks are important as they define the type of rock and its application. Latite belongs to Igneous Rocks while Arkose belongs to Sedimentary Rocks.Texture of Latite is Aphanitic to Porphyritic whereas that of Arkose is Clastic. Latite appears Rough and Arkose appears Rough and Dull. The luster of Latite is subvitreous to dull while that of Arkose is dull. Latite is available in black, brown, colourless, green, grey, pink, white colors whereas Arkose is available in reddish brown 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 Arkose are in aquifers, soil conditioner, source of magnesia (mgo), tombstones.
