Phyllite vs Gneiss

Phyllite 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 Phyllite and Gneiss Reserves. Phyllite is a fine-grained metamorphic rock with a well-developed laminar structure, and is intermediate between slate and schist rocks. 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 Phyllite vs Gneiss information and Phyllite vs Gneiss characteristics in the upcoming sections.

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

Phyllite is available in black to grey, light greenish grey colors whereas, Gneiss is available in black, brown, pink, red, white colors. Appearance of Phyllite is Crinkled or Wavy and that of Gneiss is Foliated. Properties of rock is another aspect for Phyllite vs Gneiss. The hardness of Phyllite is 1-2 and that of Gneiss is 7. The types of Phyllite are Phyllite 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 Phyllite and Gneiss is white. The specific heat capacity of Phyllite is 0.79 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.Phyllite is heat resistant, pressure resistant, water resistant whereas Gneiss is heat resistant, pressure resistant, scratch resistant, wear resistant.
