Definition
Diorite is a grey to dark-grey intermediate intrusive igneous rock composed principally of plagioclase feldspar,biotite, hornblende, and pyroxene
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

Archaeological Significance
Formation
Diorite is a coarse-grained intrusive igneous rock which contains large interlocking and randomly oriented crystals and forms when molten lava does not reach the Earth’s surface and cools down in the Earth’s crust.
Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.

More about Diorite and Diamictite
Here you can know more about Diorite and Diamictite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diorite and Diamictite consists of mineral content and compound content. The mineral content of Diorite includes Albite, Amphibole, Apatite, Biotite, Feldspar, Hornblade, Ilmenite, Magnetite, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz, Sulfides, Titanite, 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 Diorite vs Diamictite, the texture, color and appearance plays an important role in determining the type of rock. Diorite is available in black, brown, light to dark grey, white colors whereas, Diamictite is available in brown, buff colors. Appearance of Diorite is Shiny and that of Diamictite is Banded. Properties of rock is another aspect for Diorite vs Diamictite. The hardness of Diorite is 6-7 and that of Diamictite is 2-3. The types of Diorite are Plagioclase Diorite and Quartz Diorite 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 Diorite is bluish black while that of Diamictite is light to dark brown. The specific heat capacity of Diorite is 0.84 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.Diorite is heat resistant, pressure resistant, wear resistant whereas Diamictite is heat resistant, impact resistant.
