Definition
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.
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

Formation
Suevite is a metamorphic rock consisting partly of melted material, typically forming a breccia containing glass and crystal or lithic fragments, formed during an impact event.
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.

Suevite 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. Suevite vs Obsidian characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Suevite and Properties of Obsidian. Learn more about Suevite vs Obsidian in the next section. The interior uses of Suevite include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Obsidian include Decorative aggregates and Interior decoration. Due to some exceptional properties of Suevite and Obsidian, they have various applications in construction industry. The uses of Suevite in construction industry include As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories and that of Obsidian include Arrowheads, Cutting tool, Knives, Scrapers, Spear points.
More about Suevite and Obsidian
Here you can know more about Suevite and Obsidian. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Suevite and Obsidian consists of mineral content and compound content. The mineral content of Suevite includes Coesite, Quartz, Stishovite and mineral content of Obsidian is not available. You can also check out the list of all Metamorphic Rocks. When we have to compare Suevite vs Obsidian, the texture, color and appearance plays an important role in determining the type of rock. Suevite 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 Suevite is Banded and that of Obsidian is Shiny. Properties of rock is another aspect for Suevite vs Obsidian. The hardness of Suevite is 5.5 and that of Obsidian is 5-5.5. The types of Suevite are Phyllosilicates, Calcite 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 Suevite is light to dark brown while that of Obsidian is white. The specific heat capacity of Suevite 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.Suevite is heat resistant whereas Obsidian is heat resistant, impact resistant.
