Formation

Formation

Epidosite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
Earth movements can cause rocks to be either deeply buried or squeezed and hence the rocks are heated and put under great pressure.

Epidosite vs Gossan 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 Epidosite and Gossan Reserves. Epidosite is a highly altered epidote and quartz bearing rock which is a type of metasomatite, essentially altered basalt. Gossan is intensely oxidized, weathered or decomposed rock, usually the upper and exposed part of an ore deposit or mineral vein.. 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 Epidosite vs Gossan information and Epidosite vs Gossan characteristics in the upcoming sections.

Epidosite vs Gossan 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. Epidosite vs Gossan characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Epidosite and Properties of Gossan. Learn more about Epidosite vs Gossan in the next section. The interior uses of Epidosite include Decorative aggregates, Floor tiles, Homes, Hotels and Interior decoration whereas the interior uses of Gossan include Countertops, Decorative aggregates and Interior decoration. Due to some exceptional properties of Epidosite and Gossan, they have various applications in construction industry. The uses of Epidosite in construction industry include As dimension stone, Cobblestones, Rail track ballast, Roadstone and that of Gossan include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate.

More about Epidosite and Gossan

Here you can know more about Epidosite and Gossan. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Epidosite and Gossan consists of mineral content and compound content. The mineral content of Epidosite includes Olivine, Plagioclase, Pyroxene and mineral content of Gossan includes Apatite, Augite, Biotite, Bronzite, Calcite, Chert, Epidote, Feldspar, Hornblende, Micas, Plagioclase, Pyroxene, Quartz, Sulfides, Zircon. You can also check out the list of all Igneous Rocks. When we have to compare Epidosite vs Gossan, the texture, color and appearance plays an important role in determining the type of rock. Epidosite is available in black, brown, light to dark grey colors whereas, Gossan is available in brown, brown- black, gold, green, rust colors. Appearance of Epidosite is Dull and Soft and that of Gossan is Dull and Banded. Properties of rock is another aspect for Epidosite vs Gossan. The hardness of Epidosite is 6 and that of Gossan is 4-5. The types of Epidosite are Alkaline Basalt, Boninite, High Alumina Basalt, Mid Ocean Ridge Basalt (MORB), Tholeiitic Basalt, Basaltic trachyandesite, Mugearite and Shoshonite whereas types of Gossan are Translocated gossan and Leakage gossan. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Epidosite and Gossan is white to grey. The specific heat capacity of Epidosite is 0.84 kJ/Kg K and that of Gossan is 0.24 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Epidosite is heat resistant, pressure resistant, wear resistant whereas Gossan is heat resistant, impact resistant, pressure resistant.
