Shale vs Gneiss

Shale 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 Shale and Gneiss Reserves. Shale is a fine-grained sedimentary rock which is formed by the compaction of silt and clay-size mineral particles. 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 Shale vs Gneiss information and Shale vs Gneiss characteristics in the upcoming sections.

Shale 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. Shale vs Gneiss characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Shale and Properties of Gneiss. Learn more about Shale vs Gneiss in the next section. The interior uses of Shale include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Gneiss include Countertops, Decorative aggregates, Flooring and Interior decoration. Due to some exceptional properties of Shale and Gneiss, they have various applications in construction industry. The uses of Shale in construction industry include Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar and that of Gneiss include As dimension stone.

Shale is available in black, brown, buff, green, grey, red, yellow colors whereas, Gneiss is available in black, brown, pink, red, white colors. Appearance of Shale is Muddy and that of Gneiss is Foliated. Properties of rock is another aspect for Shale vs Gneiss. The hardness of Shale is 3 and that of Gneiss is 7. The types of Shale are Red Shale, Black Shale, Green Shale, Grey Shale and Yellow Shale 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 Shale and Gneiss is white. The specific heat capacity of Shale is 0.39 kJ/Kg K and that of Gneiss is 0.70 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Shale is heat resistant, impact resistant whereas Gneiss is heat resistant, pressure resistant, scratch resistant, wear resistant.
