Amphibolite vs Obsidian

Amphibolite vs Obsidian 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 Amphibolite and Obsidian Reserves. Amphibolite can be defined as a granular metamorphic rock which mainly consist of hornblende and plagioclase. Obsidian is a naturally occurring volcanic glass formed as an extrusive igneous rock. It is produced when felsic lava extruded from a volcano cools rapidly with minimum crystal growth. 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 Amphibolite vs Obsidian information and Amphibolite vs Obsidian characteristics in the upcoming sections.

Amphibolite vs Obsidian 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. Amphibolite vs Obsidian characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Amphibolite and Properties of Obsidian. Learn more about Amphibolite vs Obsidian in the next section.

Amphibolite is available in black, brown, green, grey colors whereas, Obsidian is available in black, blue, brown, green, orange, red, tan, yellow colors. Appearance of Amphibolite is Foliated and that of Obsidian is Shiny. Properties of rock is another aspect for Amphibolite vs Obsidian. The hardness of Amphibolite is 6-7 and that of Obsidian is 5-5.5. The types of Amphibolite are Hornblendite whereas types of Obsidian are Fireworks Obsidian, Mahogany, Sheen Obsidian, Snowflake obsidian and Velvet Peacock Obsidian. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Amphibolite is white to grey while that of Obsidian is white. The specific heat capacity of Amphibolite is 0.84 kJ/Kg K and that of Obsidian is 0.92 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Amphibolite is heat resistant, pressure resistant, wear resistant whereas Obsidian is heat resistant, impact resistant.
