Picrite vs Limestone

Picrite vs Limestone Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Picrite and Limestone Reserves. Picrite is a variety of high-magnesium olivine basalt that is very rich in the mineral olivine. Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Picrite vs Limestone information and Picrite vs Limestone characteristics in the upcoming sections.

Picrite vs Limestone 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. Picrite vs Limestone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Picrite and Properties of Limestone. Learn more about Picrite vs Limestone in the next section. The interior uses of Picrite include Countertops, Decorative aggregates, Homes and Interior decoration whereas the interior uses of Limestone include Decorative aggregates and Interior decoration. Due to some exceptional properties of Picrite and Limestone, they have various applications in construction industry. The uses of Picrite in construction industry include As a sintering agent in steel industry to process iron ore, Cement manufacture, For road aggregate, Manufacture of magnesium and dolomite refractories, Roadstone, Used for flooring, stair treads, borders and window sills. and that of Limestone include Cement manufacture, Cobblestones, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar, Roadstone, Source of calcium.

Picrite is available in black, brown, green, grey, pink, white, yellow colors whereas, Limestone is available in beige, black, blue, brown, cream, gold, green, grey, light green, light grey, linen, pink, red, rust, silver, white, yellow colors. Appearance of Picrite is Rough and Shiny and that of Limestone is Rough and Banded. Properties of rock is another aspect for Picrite vs Limestone. The hardness of Picrite is 6.8 and that of Limestone is 3-4. The types of Picrite are Oceanite whereas types of Limestone are Chalk, Coquina, Fossiliferous Limestone, Lithographic Limestone, Oolitic Limestone, Travertine, Tufa. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Picrite and Limestone is white, greenish white or grey. The specific heat capacity of Picrite is 0.88 kJ/Kg K and that of Limestone is 0.91 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Picrite is heat resistant whereas Limestone is pressure resistant.
