Definition
Gritstone or grit is a hard, coarse-grained, siliceous sandstone
Marble is a non-foliated metamorphic rock which is composed of recrystallized carbonate which is formed when limestone is exposed to high temperatures and pressures over a long time

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.
Marble is a metamorphic rock produced from limestone in the earth crust. It is formed by the metamorphism of limestone.

More about Gritstone and Marble
Here you can know more about Gritstone and Marble. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Gritstone and Marble consists of mineral content and compound content. The mineral content of Gritstone includes Calcite, Clay Minerals, Feldspar, Micas, Quartz and mineral content of Marble includes Garnet, Graphite, Olivine, Pyrite, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Gritstone vs Marble, the texture, color and appearance plays an important role in determining the type of rock. 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, Marble is available in black, blue, brown, grey, pink, white colors. Appearance of Gritstone is Layered and Foliated and that of Marble is Veined and Shiny. Properties of rock is another aspect for Gritstone vs Marble. The hardness of Gritstone is 6-7 and that of Marble is 3-4. The types of Gritstone are Not Available whereas types of Marble are Breccia Marble, Carrara Marble, Calacatta marble, Cultured Marble, Polished Marble, Honed Marble, Sand Marble. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Gritstone and Marble is white. The specific heat capacity of Gritstone is 0.92 kJ/Kg K and that of Marble is 0.88 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 Marble is heat resistant.
