Definition
Latite is an igneous, volcanic rock, with aphanitic-aphyric to aphyric-porphyritic texture
Norite is a mafic intrusive igneous rock composed largely of the calcium-rich plagioclase labradorite, orthopyroxene, and olivine

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.
Norite 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.

All about Latite and Norite Properties
Know all about Latite and Norite properties here. All properties of rocks are important as they define the type of rock and its application. Latite and Norite belong to Igneous Rocks.Texture of Latite is Aphanitic to Porphyritic whereas that of Norite is Phaneritic. Latite appears Rough and Norite appears Veined and Shiny. The luster of Latite is subvitreous to dull while that of Norite is not available. Latite is available in black, brown, colourless, green, grey, pink, white colors whereas Norite is available in dark grey to black 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 Norite are cemetery markers, commemorative tablets, laboratory bench tops, jewelry, sea defence, tombstones.
