Definition
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.
Greywacke is defined as a dark coarse-grained sandstone rock which contains more than 15 per cent clay

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.
Graywacke rock is a type of sedimentary rock, which is also known as immature sandstone, which is indurated, dark grey and consisting of poorly sorted angular to sub-angular, sand-sized grains.

More about Suevite and Greywacke
Here you can know more about Suevite and Greywacke. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Suevite and Greywacke consists of mineral content and compound content. The mineral content of Suevite includes Coesite, Quartz, Stishovite and mineral content of Greywacke includes Augite, Biotite, Calcite, Chlorite, Clay, Clay Minerals, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Suevite vs Greywacke, 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, Greywacke is available in beige, black, brown, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors. Appearance of Suevite is Banded and that of Greywacke is Dull. Properties of rock is another aspect for Suevite vs Greywacke. The hardness of Suevite is 5.5 and that of Greywacke is 6-7. The types of Suevite are Phyllosilicates, Calcite whereas types of Greywacke are Greywacke. 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 Greywacke is white. The specific heat capacity of Suevite is 0.92 kJ/Kg K and that of Greywacke is 0.71 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 Greywacke is heat resistant, impact resistant, pressure resistant.
