Formation
Limestone is a sedimentary rock which is mainly made up of calcium carbonate.
Turbidite is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles then settle down and are subjected to high temperature and pressures hence forming Turbidite.

Limestone vs Turbidite 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. Limestone vs Turbidite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Limestone and Properties of Turbidite. Learn more about Limestone vs Turbidite in the next section. The interior uses of Limestone include Decorative aggregates and Interior decoration whereas the interior uses of Turbidite include Bathrooms, Countertops, Decorative aggregates, Flooring, Homes and Interior decoration. Due to some exceptional properties of Limestone and Turbidite, they have various applications in construction industry. The uses of Limestone in construction industry include Cement manufacture, Cobblestones, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar, Roadstone, Source of calcium and that of Turbidite include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement.
More about Limestone and Turbidite
Here you can know more about Limestone and Turbidite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Limestone and Turbidite consists of mineral content and compound content. The mineral content of Limestone includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt and mineral content of Turbidite includes Coesite, Quartz, Sand. You can also check out the list of all Sedimentary Rocks. When we have to compare Limestone vs Turbidite, the texture, color and appearance plays an important role in determining the type of rock. Limestone is available in beige, black, blue, brown, cream, gold, green, grey, light green, light grey, linen, pink, red, rust, silver, white, yellow colors whereas, Turbidite is available in black, brown, green, grey, pink colors. Appearance of Limestone is Rough and Banded and that of Turbidite is Dull and Banded. Properties of rock is another aspect for Limestone vs Turbidite. The hardness of Limestone is 3-4 and that of Turbidite is 3. The types of Limestone are Chalk, Coquina, Fossiliferous Limestone, Lithographic Limestone, Oolitic Limestone, Travertine, Tufa whereas types of Turbidite are Sedimentary rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Limestone is white while that of Turbidite is white, greenish white or grey. The specific heat capacity of Limestone is 0.91 kJ/Kg K and that of Turbidite 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.Limestone is pressure resistant whereas Turbidite is heat resistant.
