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.

Gritstone vs Lherzolite Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Gritstone vs Lherzolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Gritstone and Properties of Lherzolite. Learn more about Gritstone vs Lherzolite in the next section. The interior uses of Gritstone include Countertops, Decorative aggregates, Homes and Interior decoration whereas the interior uses of Lherzolite include Decorative aggregates, Entryways, Homes and Interior decoration. Due to some exceptional properties of Gritstone and Lherzolite, they have various applications in construction industry. The uses of Gritstone in construction industry include Construction aggregate, Roadstone and that of Lherzolite include Landscaping, Manufacture of magnesium and dolomite refractories, Used for flooring, stair treads, borders and window sills..
More about Gritstone and Lherzolite
Here you can know more about Gritstone and Lherzolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Gritstone and Lherzolite consists of mineral content and compound content. The mineral content of Gritstone includes Calcite, Clay Minerals, Feldspar, Micas, Quartz and mineral content of Lherzolite includes Harzburgite, Olivine, Pyroxene, Pyrrhotite. You can also check out the list of all Sedimentary Rocks. When we have to compare Gritstone vs Lherzolite, 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, Lherzolite is available in black, dark greenish - grey, green, pink, purple colors. Appearance of Gritstone is Layered and Foliated and that of Lherzolite is Glassy, Vesicular and Foilated. Properties of rock is another aspect for Gritstone vs Lherzolite. The hardness of Gritstone is 6-7 and that of Lherzolite is 6.5. The types of Gritstone are Not Available whereas types of Lherzolite are Garnet Lherzolite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Gritstone and Lherzolite is white. The specific heat capacity of Gritstone is 0.92 kJ/Kg K and that of Lherzolite 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 Lherzolite is heat resistant, impact resistant, pressure resistant, wear resistant.
