Definition
Definition
Latite is an igneous, volcanic rock, with aphanitic-aphyric to aphyric-porphyritic texture
Ijolite is an intrusive igneous rock which is composed mainly of nepheline and an alkali pyroxene, usually aegirine-augite

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.
Ijolite 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 Ijolite Properties
Know all about Latite and Ijolite properties here. All properties of rocks are important as they define the type of rock and its application. Latite and Ijolite belong to Igneous Rocks.Texture of Latite is Aphanitic to Porphyritic whereas that of Ijolite is Earthy, Granular. Latite appears Rough and Ijolite appears Banded and Foilated. The luster of Latite is subvitreous to dull while that of Ijolite is greasy to dull. Latite is available in black, brown, colourless, green, grey, pink, white colors whereas Ijolite is available in brown, buff, cream, green, grey, pink, 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 Ijolite are cemetery markers, creating artwork.
