Definition
Gabbro is an intrusive igneous rock which is chemically equivalent to plutonic Basalt
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.

More about Gabbro and Suevite
Here you can know more about Gabbro and Suevite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Gabbro and Suevite consists of mineral content and compound content. The mineral content of Gabbro includes Augite, Olivine, Plagioclase, Pyroxene and mineral content of Suevite includes Coesite, Quartz, Stishovite. You can also check out the list of all Igneous Rocks. When we have to compare Gabbro vs Suevite, the texture, color and appearance plays an important role in determining the type of rock. Gabbro is available in dark grey to black colors whereas, Suevite is available in black, brown, green, grey, pink colors. Appearance of Gabbro is Veined and Shiny and that of Suevite is Banded. Properties of rock is another aspect for Gabbro vs Suevite. The hardness of Gabbro is 7 and that of Suevite is 5.5. The types of Gabbro are Anorthosite Gabbro and Norite Gabbro whereas types of Suevite are Phyllosilicates, Calcite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Gabbro is black while that of Suevite is light to dark brown. The specific heat capacity of Gabbro is 0.71 kJ/Kg K and that of Suevite 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.Gabbro is impact resistant, pressure resistant, wear resistant whereas Suevite is heat resistant.
