Definition
A sedimentary rock, deposit of a submarine turbidity currents and are composed of layered particles
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
Origin
European Foreland Basins
Ethiopia
Discoverer

Obsius
Etymology
From Medieval Latin turbiditas, from Latin turbidus (turbid). Turbidity current is from 1939
From Latin obsidianus, misprint of Obsianus (lapis) (stone) of Obsius

Formation
Turbidite is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles then settle down and are subjected to high temperature and pressures hence forming Turbidite.
When the lava is released from volcano, it undergoes a very rapid cooling which freezes the mechanisms of crystallization. The result is a volcanic glass with a uniform smooth texture.

Turbidite 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. Turbidite vs Obsidian characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Turbidite and Properties of Obsidian. Learn more about Turbidite vs Obsidian in the next section. The interior uses of Turbidite include Bathrooms, Countertops, Decorative aggregates, Flooring, Homes and Interior decoration whereas the interior uses of Obsidian include Decorative aggregates and Interior decoration. Due to some exceptional properties of Turbidite and Obsidian, they have various applications in construction industry. The uses of Turbidite in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement and that of Obsidian include Arrowheads, Cutting tool, Knives, Scrapers, Spear points.
More about Turbidite and Obsidian
Here you can know more about Turbidite and Obsidian. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Turbidite and Obsidian consists of mineral content and compound content. The mineral content of Turbidite includes Coesite, Quartz, Sand and mineral content of Obsidian is not available. You can also check out the list of all Sedimentary Rocks. When we have to compare Turbidite vs Obsidian, the texture, color and appearance plays an important role in determining the type of rock. Turbidite is available in black, brown, colourless, green, grey, pink colors whereas, Obsidian is available in black, blue, brown, green, orange, red, tan, yellow colors. Appearance of Turbidite is Dull and Banded and that of Obsidian is Shiny. Properties of rock is another aspect for Turbidite vs Obsidian. The hardness of Turbidite is 3 and that of Obsidian is 5-5.5. The types of Turbidite 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 Turbidite and Obsidian is white, greenish white or grey. The specific heat capacity of Turbidite 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.Turbidite is heat resistant whereas Obsidian is heat resistant, impact resistant.
