Definition
Latite is an igneous, volcanic rock, with aphanitic-aphyric to aphyric-porphyritic texture
Borolanite is a variety of Nepheline Syenite and belongs to igneous rocks and contains nepheline-alkali feldspar pseudomorphs which occur as conspicuous white spots in the dark rock matrix

Archaeological Significance
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.
Borolanites are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.

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