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 Trondhjemite and Obsidian Reserves. Trondhjemite is a leucocratic (light-colored) intrusive igneous rock. It is a variety of tonalite in which the plagioclase is mostly in the form of oligoclase. Trondhjemites are sometimes known as plagiogranites.. 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 Trondhjemite vs Obsidian information and Trondhjemite vs Obsidian characteristics in the upcoming sections.
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. Trondhjemite vs Obsidian characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Trondhjemite and Properties of Obsidian. Learn more about Trondhjemite vs Obsidian in the next section. The interior uses of Trondhjemite include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration whereas the interior uses of Obsidian include Decorative aggregates and Interior decoration. Due to some exceptional properties of Trondhjemite and Obsidian, they have various applications in construction industry. The uses of Trondhjemite in construction industry include As dimension stone, Cement manufacture, Cobblestones, Construction aggregate, For road aggregate and that of Obsidian include Arrowheads, Cutting tool, Knives, Scrapers, Spear points.
Here you can know more about Trondhjemite and Obsidian. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock.

You can also check out the list of all Igneous Rocks. When we have to compare Trondhjemite vs Obsidian, the texture, color and appearance plays an important role in determining the type of rock. Trondhjemite is available in black, brown, light to dark grey, white colors whereas, Obsidian is available in black, blue, brown, green, orange, red, tan, yellow colors. Appearance of Trondhjemite is Banded and Foilated and that of Obsidian is Shiny. Properties of rock is another aspect for Trondhjemite vs Obsidian. The hardness of Trondhjemite is 6-7 and that of Obsidian is 5-5.5. The types of Trondhjemite are Not Available 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 Trondhjemite is bluish black while that of Obsidian is white. The specific heat capacity of Trondhjemite is 0.92 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.Trondhjemite is heat resistant, pressure resistant, wear resistant whereas Obsidian is heat resistant, impact resistant.
