Dacite vs Variolite

Dacite 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 Dacite and Variolite Reserves. Dacite is a volcanic igneous rock which is rintermediate in composition between andesite and rhyolite. 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 Dacite vs Variolite information and Dacite vs Variolite characteristics in the upcoming sections.

Dacite is available in bluish - grey, brown, grey, light to dark grey colors whereas, Variolite is available in black, brown, light to dark grey colors. Appearance of Dacite is Vesicular and that of Variolite is Dull and Soft. Properties of rock is another aspect for Dacite vs Variolite. The hardness of Dacite is 2-2.25 and that of Variolite is 6. The types of Dacite are Footwall Dacite, Hanging wall Dacite, Tuff and Biotite Dacite 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 Dacite is white while that of Variolite is white to grey. The specific heat capacity of Dacite 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.Dacite is heat resistant, impact resistant, pressure resistant, wear resistant whereas Variolite is heat resistant, pressure resistant, wear resistant.
