Shoshonite vs Hornblendite 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 Shoshonite and Hornblendite Reserves. Shoshonite is a basaltic rock, properly a potassic trachyandesite, composed of olivine, augite and plagioclase phenocrysts in a groundmass with calcic plagioclase and sanidine and some dark-colored volcanic glass. Hornblendite is a type of igneous plutonic rock consisting mainly of amphibole hornblende and is a type of Amphibolite rock. 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 Shoshonite vs Hornblendite information and Shoshonite vs Hornblendite characteristics in the upcoming sections.

More about Shoshonite and Hornblendite

Here you can know more about Shoshonite and Hornblendite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Shoshonite and Hornblendite consists of mineral content and compound content. The mineral content of Shoshonite includes Pyroxene and mineral content of Hornblendite includes Amphibole, Calcite, Hornblade, Magnetite, Plagioclase, Wollastonite. You can also check out the list of all Igneous Rocks. When we have to compare Shoshonite vs Hornblendite, the texture, color and appearance plays an important role in determining the type of rock. Shoshonite is available in brown- black, dark brown colors whereas, Hornblendite is available in black, brown, green, grey colors. Appearance of Shoshonite is Dull and that of Hornblendite is Foliated. Properties of rock is another aspect for Shoshonite vs Hornblendite. The hardness of Shoshonite is 6 and that of Hornblendite is 6-7. The types of Shoshonite are Intermediate volcanic rock whereas types of Hornblendite are Hornblende Gabbro and Hornblende Peridotite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Shoshonite and Hornblendite is white to grey. The specific heat capacity of Shoshonite is 0.79 kJ/Kg K and that of Hornblendite 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.Shoshonite is heat resistant, pressure resistant whereas Hornblendite is heat resistant, pressure resistant, wear resistant.
