Limestone vs Gneiss

Limestone vs Gneiss 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 Limestone and Gneiss Reserves. Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate. Gneiss is a common and widely distributed type of rock formed by high-grade regional metamorphic processes from pre-existing formations that were originally either igneous or sedimentary rocks. 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 Limestone vs Gneiss information and Limestone vs Gneiss characteristics in the upcoming sections.

Limestone vs Gneiss 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 Gneiss characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Limestone and Properties of Gneiss. Learn more about Limestone vs Gneiss in the next section. The interior uses of Limestone include Decorative aggregates and Interior decoration whereas the interior uses of Gneiss include Countertops, Decorative aggregates, Flooring and Interior decoration. Due to some exceptional properties of Limestone and Gneiss, 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 Gneiss include As dimension stone.

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, Gneiss is available in black, brown, pink, red, white colors. Appearance of Limestone is Rough and Banded and that of Gneiss is Foliated. Properties of rock is another aspect for Limestone vs Gneiss. The hardness of Limestone is 3-4 and that of Gneiss is 7. The types of Limestone are Chalk, Coquina, Fossiliferous Limestone, Lithographic Limestone, Oolitic Limestone, Travertine, Tufa whereas types of Gneiss are Augen Gneiss, Henderson Gneiss, Lewisian Gneiss, Archean and Proterozoic Gneiss.. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Limestone and Gneiss is white. The specific heat capacity of Limestone is 0.91 kJ/Kg K and that of Gneiss is Not Available. 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 Gneiss is heat resistant, pressure resistant, scratch resistant, wear resistant.
