Formation
Essexite is a type of igneous rock, which is usually dark grey to black plutonic rock. For the formation of essexite, suitable magma with exact composition of K, Ba, Rb, Cs, Sr should be produced.
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 Essexite and Latite Properties
Know all about Essexite and Latite properties here. All properties of rocks are important as they define the type of rock and its application. Essexite and Latite belong to Igneous Rocks.Texture of Essexite is Granular whereas that of Latite is Aphanitic to Porphyritic. Essexite appears Banded and Latite appears Rough. The luster of Essexite is not available while that of Latite is subvitreous to dull. Essexite is available in dark grey to black colors whereas Latite is available in black, brown, colourless, green, grey, pink, white colors. The commercial uses of Essexite are cemetery markers, commemorative tablets, jewelry, sea defence, tombstones and that of Latite are an oil and gas reservoir, as a feed additive for livestock, metallurgical flux, soil conditioner, source of magnesia (mgo).
