Definition
Andesite is a dark, fine-grained, brown or greyish intermediate volcanic rock which is a commonly found in lava
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.

Formation
Andesite is a fine-grained igneous rock that forms when the magma is erupted onto the surface and is crystallized quickly.
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.

Andesite 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. Andesite vs Suevite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Andesite and Properties of Suevite. Learn more about Andesite vs Suevite in the next section. The interior uses of Andesite include Decorative aggregates, Floor tiles, Homes, Interior decoration and Kitchens whereas the interior uses of Suevite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Andesite and Suevite, they have various applications in construction industry. The uses of Andesite in construction industry include Cobblestones, Construction aggregate, For road aggregate and that of Suevite include As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories.
More about Andesite and Suevite
Here you can know more about Andesite and Suevite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Andesite and Suevite consists of mineral content and compound content. The mineral content of Andesite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite, Magnetite, Plagioclase, Pyroxene, Zircon 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 Andesite vs Suevite, the texture, color and appearance plays an important role in determining the type of rock. Andesite is available in bluish - grey, grey, pink, yellow colors whereas, Suevite is available in black, brown, colourless, green, grey, pink colors. Appearance of Andesite is Dull and Soft and that of Suevite is Banded. Properties of rock is another aspect for Andesite vs Suevite. The hardness of Andesite is 7 and that of Suevite is 5.5. The types of Andesite are Icelandite 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 Andesite is white while that of Suevite is light to dark brown. The specific heat capacity of Andesite is 2.39 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.Andesite is heat resistant, pressure resistant, wear resistant whereas Suevite is heat resistant.
