Felsite vs Variolite

Felsite vs Variolite 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 Felsite and Variolite Reserves. Felsite is a very fine grained volcanic rock that may or may not contain larger crystals and light colored rock that typically requires petrographic examination or chemical analysis for more precise definition. Variolites are a group of dark green basic igneous rocks which exhibit pale colored spots, or spherules, especially on weathered surfaces, that give them a pockmarked appearance. 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 Felsite vs Variolite information and Felsite vs Variolite characteristics in the upcoming sections.

Felsite vs Variolite 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. Felsite vs Variolite characteristics assist us to distinguish and recognize rocks.

The mineral content of Felsite includes Feldspar, Iron Oxides and mineral content of Variolite includes Olivine, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Felsite vs Variolite, the texture, color and appearance plays an important role in determining the type of rock. Felsite is available in black, blue, brown, green, orange, red, tan, yellow colors whereas, Variolite is available in black, brown, light to dark grey colors. Appearance of Felsite is Layered, Banded, Veined and Shiny and that of Variolite is Dull and Soft. Properties of rock is another aspect for Felsite vs Variolite. The hardness of Felsite is 5-5.5 and that of Variolite is 6. The types of Felsite are Igneous rock whereas types of Variolite are Metamorphic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Felsite is white while that of Variolite is white to grey. The specific heat capacity of Felsite is 0.92 kJ/Kg K and that of Variolite is 0.84 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Felsite is heat resistant, impact resistant whereas Variolite is heat resistant, pressure resistant, wear resistant.
