Latite and Eclogite
Definition
Definition
Latite is an igneous, volcanic rock, with aphanitic-aphyric to aphyric-porphyritic texture
Eclogite is an extreme metamorphic rock, formed by regional metamorphism of basalt rock under very high pressure and temperature

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.
Eclogite forms from high-pressure metamorphism of mafic igneous rocks mainly, basalt or gabbro as it plunges into the mantle in a subduction zone.

All about Latite and Eclogite Properties
Know all about Latite and Eclogite properties here. All properties of rocks are important as they define the type of rock and its application. Latite belongs to Igneous Rocks while Eclogite belongs to Metamorphic Rocks.Texture of Latite is Aphanitic to Porphyritic whereas that of Eclogite is Earthy. Latite appears Rough and Eclogite appears Dull, Banded and Foilated. The luster of Latite and Eclogite is subvitreous to dull. Latite and Eclogite are available in black, brown, colourless, 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 Eclogite are creating artwork, gemstone.
