5 Formation

5.1 Formation

Shale forms when very fine-grained clay particles are deposited in water which settle at the bottom of water bodies. They are later compacted hence forming shale.

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 Shale and Latite Properties

Know all about Shale and Latite properties here. All properties of rocks are important as they define the type of rock and its application. Shale belongs to Sedimentary Rocks while Latite belongs to Igneous Rocks.Texture of Shale is Clastic, Splintery whereas that of Latite is Aphanitic to Porphyritic. Shale appears Muddy and Latite appears Rough. The luster of Shale is dull while that of Latite is subvitreous to dull. Shale is available in black, brown, buff, green, grey, red, yellow colors whereas Latite is available in black, brown, colourless, green, grey, pink, white colors. The commercial uses of Shale are creating artwork, pottery and that of Latite are an oil and gas reservoir, as a feed additive for livestock, metallurgical flux, soil conditioner, source of magnesia (mgo).
