Formation
Oolites form when layers of calcite are deposited around a sand grain or fossil piece and are rolled around in calm water, which makes them round.
Sandstone is a sedimentary rock which forms from cemented sand-sized clasts. It forms when sand layers are buried under sediments of sand.

Oolite vs Sandstone 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. Oolite vs Sandstone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Oolite and Properties of Sandstone. Learn more about Oolite vs Sandstone in the next section. The interior uses of Oolite include Decorative aggregates, Flooring and Interior decoration whereas the interior uses of Sandstone include Countertops, Decorative aggregates and Interior decoration. Due to some exceptional properties of Oolite and Sandstone, they have various applications in construction industry. The uses of Oolite in construction industry include Cement manufacture, Cobblestones, Landscaping and that of Sandstone include Cement manufacture, Construction aggregate, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar.
More about Oolite and Sandstone
Here you can know more about Oolite and Sandstone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Oolite and Sandstone consists of mineral content and compound content. The mineral content of Oolite includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt and mineral content of Sandstone includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Oolite vs Sandstone, the texture, color and appearance plays an important role in determining the type of rock. Oolite is available in black, blue, brown, cream, green, grey, pink, red, silver, white, yellow colors whereas, Sandstone is available in beige, black, brown, colourless, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors. Appearance of Oolite is Rounded and Rough and that of Sandstone is Rough. Properties of rock is another aspect for Oolite vs Sandstone. The hardness of Oolite is 3-4 and that of Sandstone is 6-7. The types of Oolite are Not Available whereas types of Sandstone are Grey Sandstones, Crystallized Sandstones, Hard Sandstones , Carbonate Cemented Sandstones and Ganister. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Oolite and Sandstone is white. The specific heat capacity of Oolite is Not Available and that of Sandstone is 0.92 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Oolite is heat resistant, wear resistant whereas Sandstone is heat resistant, impact resistant, pressure resistant.
