Formation
Hornblendite 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.
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.

All about Hornblendite and Latite Properties
Know all about Hornblendite and Latite properties here. All properties of rocks are important as they define the type of rock and its application. Hornblendite and Latite belong to Igneous Rocks.Texture of Hornblendite is Banded, Foliated, Massive whereas that of Latite is Aphanitic to Porphyritic. Hornblendite appears Foliated and Latite appears Rough. The luster of Hornblendite is vitreous to dull while that of Latite is subvitreous to dull. Hornblendite is available in black, brown, green, grey colors whereas Latite is available in black, brown, colourless, green, grey, pink, white colors. The commercial uses of Hornblendite are cemetery markers, commemorative tablets, creating artwork and that of Latite are an oil and gas reservoir, as a feed additive for livestock, metallurgical flux, soil conditioner, source of magnesia (mgo).
