Definition
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
Andesite is a dark, fine-grained, brown or greyish intermediate volcanic rock which is a commonly found in lava

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

More about Diamictite and Andesite
Here you can know more about Diamictite and Andesite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diamictite and Andesite consists of mineral content and compound content. The mineral content of Diamictite includes Calcite, Clay, Feldspar, Micas, Quartz and mineral content of Andesite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite, Magnetite, Plagioclase, Pyroxene, Zircon. You can also check out the list of all Sedimentary Rocks. When we have to compare Diamictite vs Andesite, the texture, color and appearance plays an important role in determining the type of rock. Diamictite is available in brown, buff colors whereas, Andesite is available in bluish - grey, grey, pink, yellow colors. Appearance of Diamictite is Banded and that of Andesite is Dull and Soft. Properties of rock is another aspect for Diamictite vs Andesite. The hardness of Diamictite is 2-3 and that of Andesite is 7. The types of Diamictite are Bedded Diamictite and Laminated Diamictite whereas types of Andesite are Icelandite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Diamictite is light to dark brown while that of Andesite is white. The specific heat capacity of Diamictite is 0.75 kJ/Kg K and that of Andesite is 2.39 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Diamictite is heat resistant, impact resistant whereas Andesite is heat resistant, pressure resistant, wear resistant.
