Definition
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.
Gneiss is a common and widely distributed type of rock formed by high-grade regional metamorphic processes from pre-existing formations that were originally either igneous or sedimentary rocks

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.
Gneiss is a high grade metamorphic rock i.e. it has been subjected to higher temperatures and pressures than schist. It is formed by the metamorphosis of Gneiss forms from volcanic rock, shale or granitie.

Suevite vs Gneiss 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 Gneiss characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Suevite and Properties of Gneiss. Learn more about Suevite vs Gneiss in the next section. The interior uses of Suevite include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Gneiss include Countertops, Decorative aggregates, Flooring and Interior decoration. Due to some exceptional properties of Suevite and Gneiss, 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 Gneiss include As dimension stone.
More about Suevite and Gneiss
Here you can know more about Suevite and Gneiss. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Suevite and Gneiss consists of mineral content and compound content. The mineral content of Suevite includes Coesite, Quartz, Stishovite and mineral content of Gneiss includes Biotite, Chlorite, Feldspar, Garnet, Graphite, Hornblade, Micas, Muscovite or Illite, Quartz, Quartzite, Silica, Zircon. You can also check out the list of all Metamorphic Rocks. When we have to compare Suevite vs Gneiss, 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, Gneiss is available in black, brown, pink, red, white colors. Appearance of Suevite is Banded and that of Gneiss is Foliated. Properties of rock is another aspect for Suevite vs Gneiss. The hardness of Suevite is 5.5 and that of Gneiss is 7. The types of Suevite are Phyllosilicates, Calcite whereas types of Gneiss are Augen Gneiss, Henderson Gneiss, Lewisian Gneiss, Archean and Proterozoic Gneiss.. 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 Gneiss is white. The specific heat capacity of Suevite is 0.92 kJ/Kg K and that of Gneiss is Not Available. 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 Gneiss is heat resistant, pressure resistant, scratch resistant, wear resistant.
