5 Formation

5.1 Formation

Gritstone is a type of sedimentary rock which was formed on the floors of wide river deltas where the grit deposits were laid down, with every tide or flood dumping another layer of sediment.

Lherzolite 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 Gritstone and Lherzolite Properties

Know all about Gritstone and Lherzolite properties here. All properties of rocks are important as they define the type of rock and its application. Gritstone belongs to Sedimentary Rocks while Lherzolite belongs to Igneous Rocks.Texture of Gritstone is Earthy whereas that of Lherzolite is Grenue. Gritstone appears Layered and Foliated and Lherzolite appears Glassy, Vesicular and Foilated. The luster of Gritstone is dull while that of Lherzolite is subvitreous to dull. Gritstone is available in beige, black, brown, colourless, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors whereas Lherzolite is available in black, dark greenish - grey, green, pink, purple colors. The commercial uses of Gritstone are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux, production of lime, soil conditioner, source of magnesia (mgo), tombstones and that of Lherzolite are as armour rock for sea walls, source of magnesia (mgo), used in aquariums.
