Schist vs Variolite

Schist 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 Schist and Variolite Reserves. Schist is a medium grade metamorphic rock with medium to large, flat, sheet like grains in a preferred orientation. 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 Schist vs Variolite information and Schist vs Variolite characteristics in the upcoming sections.

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

Schist is available in black, blue, brown, dark brown, green, grey, silver colors whereas, Variolite is available in black, brown, light to dark grey colors. Appearance of Schist is Layered and Shiny and that of Variolite is Dull and Soft. Properties of rock is another aspect for Schist vs Variolite. The hardness of Schist is 3.5-4 and that of Variolite is 6. The types of Schist are Mica Schists, Calc-Silicate Schists, Graphite Schists, Blueschists, Whiteschists, Greenschists, Hornblende Schist, Talc Schist, Chlorite Schist, Garnet Schist, Glaucophane schist. 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 Schist is white while that of Variolite is white to grey. The specific heat capacity of Schist is 0.70 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.Schist is impact resistant, pressure resistant, water resistant whereas Variolite is heat resistant, pressure resistant, wear resistant.
