Argillite vs Gneiss

Argillite 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 Argillite and Gneiss Reserves. Argillites are highly compact sedimentary or slightly metamorphosed rocks that consist largely or wholly of particles of clay or silt but lack the fissility of shale or the cleavage characteristic of slate. 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 Argillite vs Gneiss information and Argillite vs Gneiss characteristics in the upcoming sections.

Argillite 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. Argillite vs Gneiss characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Argillite and Properties of Gneiss. Learn more about Argillite vs Gneiss in the next section. The interior uses of Argillite 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 Argillite and Gneiss, they have various applications in construction industry. The uses of Argillite in construction industry include Used for flooring, stair treads, borders and window sills. and that of Gneiss include As dimension stone.

Argillite is available in dark grey to black, pink, red, white colors whereas, Gneiss is available in black, brown, pink, red, white colors. Appearance of Argillite is Rough and Dull and that of Gneiss is Foliated. Properties of rock is another aspect for Argillite vs Gneiss. The hardness of Argillite is 2-3 and that of Gneiss is 7. The types of Argillite are Metamorphic rock 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 Argillite is white to grey while that of Gneiss is white. The specific heat capacity of Argillite is 0.87 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.Argillite is heat resistant, impact resistant whereas Gneiss is heat resistant, pressure resistant, scratch resistant, wear resistant.
