5.1 Formation
Basalt forms when lava reaches the Earth's surface near an active volcano. The temperature of lava is between 1100 to 1250° C when it gets to the surface.
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.

Basalt vs Epidosite 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 Basalt and Epidosite Reserves. Basalt is a common extrusive igneous rock formed by the rapid cooling of basaltic lava exposed at or very near the surface of Earth. Epidosite is a highly altered epidote and quartz bearing rock which is a type of metasomatite, essentially altered basalt. 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 Basalt vs Epidosite information and Basalt vs Epidosite characteristics in the upcoming sections.

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

More about Basalt and Epidosite

Here you can know more about Basalt and Epidosite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Basalt and Epidosite consists of mineral content and compound content. The mineral content of Basalt includes Olivine, Plagioclase, Pyroxene and mineral content of Epidosite includes Olivine, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Basalt vs Epidosite, the texture, color and appearance plays an important role in determining the type of rock. Basalt is available in black, brown, light to dark grey colors whereas, Epidosite is available in black, brown, light to dark grey colors. Appearance of Basalt is Dull and Soft and that of Epidosite is Dull and Soft. Properties of rock is another aspect for Basalt vs Epidosite. Hardness of Basalt and Epidosite is 6.
