Epidosite vs Theralite 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 Theralite Reserves. Epidosite is a highly altered epidote and quartz bearing rock which is a type of metasomatite, essentially altered basalt. Theralite is a plutonic hylocrystalline igneous rock consisting of augite, olivine, calcic plagioclase and nepheline. 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 Theralite information and Epidosite vs Theralite characteristics in the upcoming sections.

Epidosite vs Theralite 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 Theralite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Epidosite and Properties of Theralite. Learn more about Epidosite vs Theralite in the next section. The interior uses of Epidosite include Decorative aggregates, Floor tiles, Homes, Hotels and Interior decoration whereas the interior uses of Theralite include Decorative aggregates, Flooring and Interior decoration. Due to some exceptional properties of Epidosite and Theralite, 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 Theralite include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate.

More about Epidosite and Theralite

Here you can know more about Epidosite and Theralite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Epidosite and Theralite consists of mineral content and compound content. The mineral content of Epidosite includes Olivine, Plagioclase, Pyroxene and mineral content of Theralite includes Augite, Olivine, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Epidosite vs Theralite, 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, Theralite is available in dark grey to black colors. Appearance of Epidosite is Dull and Soft and that of Theralite is Veined and Shiny. Properties of rock is another aspect for Epidosite vs Theralite. The hardness of Epidosite is 6 and that of Theralite is 7. 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 Theralite are Teschenite and Essexite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Epidosite is white to grey while that of Theralite is white. The specific heat capacity of Epidosite is 0.84 kJ/Kg K and that of Theralite is 0.74 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 Theralite is impact resistant, pressure resistant, wear resistant.
