Definition
Hornblendite is a type of igneous plutonic rock consisting mainly of amphibole hornblende and is a type of Amphibolite rock
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.

Archaeological Significance
Formation
Hornblendite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
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.

Hornblendite vs Suevite 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. Hornblendite vs Suevite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Hornblendite and Properties of Suevite. Learn more about Hornblendite vs Suevite in the next section. The interior uses of Hornblendite include Countertops, Decorative aggregates, Entryways, Flooring, Homes, Hotels, Interior decoration and Kitchens whereas the interior uses of Suevite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Hornblendite and Suevite, they have various applications in construction industry. The uses of Hornblendite in construction industry include As dimension stone, Building houses or walls, Cobblestones, Construction aggregate, For road aggregate, Landscaping, Production of glass and ceramics, Roadstone and that of Suevite include As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories.
More about Hornblendite and Suevite
Here you can know more about Hornblendite and Suevite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Hornblendite and Suevite consists of mineral content and compound content. The mineral content of Hornblendite includes Amphibole, Calcite, Hornblade, Magnetite, Plagioclase, Wollastonite 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 Hornblendite vs Suevite, the texture, color and appearance plays an important role in determining the type of rock. Hornblendite is available in black, brown, green, grey colors whereas, Suevite is available in black, brown, green, grey, pink colors. Appearance of Hornblendite is Foliated and that of Suevite is Banded. Properties of rock is another aspect for Hornblendite vs Suevite. The hardness of Hornblendite is 6-7 and that of Suevite is 5.5. The types of Hornblendite are Hornblende Gabbro and Hornblende Peridotite 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 Hornblendite is white to grey while that of Suevite is light to dark brown. The specific heat capacity of Hornblendite is 0.84 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.Hornblendite is heat resistant, pressure resistant, wear resistant whereas Suevite is heat resistant.
