Limestone vs Obsidian

Limestone 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 Limestone and Obsidian Reserves. Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate. 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 Limestone vs Obsidian information and Limestone vs Obsidian characteristics in the upcoming sections.

Limestone 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. Limestone vs Obsidian characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Limestone and Properties of Obsidian. Learn more about Limestone vs Obsidian in the next section. The interior uses of Limestone include Decorative aggregates and Interior decoration whereas the interior uses of Obsidian include Decorative aggregates and Interior decoration. Due to some exceptional properties of Limestone and Obsidian, they have various applications in construction industry. The uses of Limestone in construction industry include Cement manufacture, Cobblestones, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar, Roadstone, Source of calcium and that of Obsidian include Arrowheads, Cutting tool, Knives, Scrapers, Spear points.

More about Limestone and Obsidian

Here you can know more about Limestone and Obsidian. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Limestone and Obsidian consists of mineral content and compound content. The mineral content of Limestone includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt and mineral content of Obsidian is not available. You can also check out the list of all Sedimentary Rocks. When we have to compare Limestone vs Obsidian, the texture, color and appearance plays an important role in determining the type of rock. Limestone is available in beige, black, blue, brown, cream, gold, green, grey, light green, light grey, linen, pink, red, rust, silver, white, yellow colors whereas, Obsidian is available in black, blue, brown, green, orange, red, tan, yellow colors. Appearance of Limestone is Rough and Banded and that of Obsidian is Shiny. Properties of rock is another aspect for Limestone vs Obsidian. The hardness of Limestone is 3-4 and that of Obsidian is 5-5.5. The types of Limestone are Chalk, Coquina, Fossiliferous Limestone, Lithographic Limestone, Oolitic Limestone, Travertine, Tufa 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 Limestone and Obsidian is white. The specific heat capacity of Limestone is 0.91 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.Limestone is pressure resistant whereas Obsidian is heat resistant, impact resistant.
