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.
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Jadeitite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

All about Gritstone and Jadeitite Properties
Know all about Gritstone and Jadeitite properties here. All properties of rocks are important as they define the type of rock and its application. Gritstone belongs to Sedimentary Rocks while Jadeitite belongs to Metamorphic Rocks.Texture of Gritstone is Earthy whereas that of Jadeitite is Earthy. Gritstone appears Layered and Foliated and Jadeitite appears Rough and Dull. The luster of Gritstone is dull while that of Jadeitite is waxy and dull. Gritstone and Jadeitite are available in beige, black, brown, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow 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 Jadeitite are commemorative tablets, creating artwork, jewelry.
