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.

More about Gritstone and Jadeitite
Here you can know more about Gritstone and Jadeitite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Gritstone and Jadeitite consists of mineral content and compound content. The mineral content of Gritstone includes Calcite, Clay Minerals, Feldspar, Micas, Quartz and mineral content of Jadeitite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides. You can also check out the list of all Sedimentary Rocks. When we have to compare Gritstone vs Jadeitite, the texture, color and appearance plays an important role in determining the type of rock. Gritstone is available in beige, black, brown, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors whereas, Jadeitite is available in black, brown, green, grey, white colors. Appearance of Gritstone is Layered and Foliated and that of Jadeitite is Rough and Dull. Properties of rock is another aspect for Gritstone vs Jadeitite. The hardness of Gritstone is 6-7 and that of Jadeitite is 3-5. The types of Gritstone are Sedimentary rock whereas types of Jadeitite are Metamorphic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Gritstone is white while that of Jadeitite is white, greenish white or grey. The specific heat capacity of Gritstone is 0.92 kJ/Kg K and that of Jadeitite is 0.95 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Gritstone is heat resistant, impact resistant, pressure resistant whereas Jadeitite is heat resistant, water resistant.
