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

Archaeological Significance
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.

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 includes . 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, 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.
