Formation
Epidosite 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 Epidosite and Latite Properties
Know all about Epidosite and Latite properties here. All properties of rocks are important as they define the type of rock and its application. Epidosite and Latite belong to Igneous Rocks.Texture of Epidosite is Glassy, Massive, Porphyritic, Scoriaceous, Vesicular whereas that of Latite is Aphanitic to Porphyritic. Epidosite appears Dull and Soft and Latite appears Rough. The luster of Epidosite is not available while that of Latite is subvitreous to dull. Epidosite is available in black, brown, light to dark grey colors whereas Latite is available in black, brown, colourless, green, grey, pink, white colors. The commercial uses of Epidosite are 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).
