Definition
Definition
Latite is an igneous, volcanic rock, with aphanitic-aphyric to aphyric-porphyritic texture
Diorite is a grey to dark-grey intermediate intrusive igneous rock composed principally of plagioclase feldspar,biotite, hornblende, and pyroxene

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.
Diorite is a coarse-grained intrusive igneous rock which contains large interlocking and randomly oriented crystals and forms when molten lava does not reach the Earth’s surface and cools down in the Earth’s crust.

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