Definition
Andesite is a dark, fine-grained, brown or greyish intermediate volcanic rock which is a commonly found in lava
Diamictite is a sedimentary rock that consists of non-sorted to poorly sorted terrigenous sediment containing particles that range in size from clay to boulders, suspended in a matrix of mudstone or sandstone

Formation
Andesite is a fine-grained igneous rock that forms when the magma is erupted onto the surface and is crystallized quickly.
Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.

Andesite vs Diamictite 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 Diamictite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Andesite and Properties of Diamictite. Learn more about Andesite vs Diamictite in the next section. The interior uses of Andesite include Decorative aggregates, Floor tiles, Homes, Interior decoration and Kitchens whereas the interior uses of Diamictite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Andesite and Diamictite, they have various applications in construction industry. The uses of Andesite in construction industry include Cobblestones, Construction aggregate, For road aggregate and that of Diamictite include As dimension stone, Construction aggregate, For road aggregate, Landscaping, Roadstone.
More about Andesite and Diamictite
Here you can know more about Andesite and Diamictite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Andesite and Diamictite 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 Diamictite includes Calcite, Clay, Feldspar, Micas, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Andesite vs Diamictite, 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, Diamictite is available in brown, buff colors. Appearance of Andesite is Dull and Soft and that of Diamictite is Banded. Properties of rock is another aspect for Andesite vs Diamictite. The hardness of Andesite is 7 and that of Diamictite is 2-3. The types of Andesite are Icelandite whereas types of Diamictite are Bedded Diamictite and Laminated Diamictite. 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 Diamictite is light to dark brown. The specific heat capacity of Andesite is 2.39 kJ/Kg K and that of Diamictite is 0.75 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 Diamictite is heat resistant, impact resistant.
