Definition
Diorite is a grey to dark-grey intermediate intrusive igneous rock composed principally of plagioclase feldspar,biotite, hornblende, and pyroxene
A carbonate rock which is matrix supported and contains over 10% allochems in a carbonate mud matrix.

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.
Wackestone is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles settle down and are then compacted due to high temperature and pressure hence forming Wackestone.

More about Diorite and Wackestone
Here you can know more about Diorite and Wackestone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diorite and Wackestone 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 Wackestone includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Diorite vs Wackestone, 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, Wackestone is available in black, blue, brown, green, grey, orange, red, white, yellow colors. Appearance of Diorite is Shiny and that of Wackestone is Rough and Dull. Properties of rock is another aspect for Diorite vs Wackestone. The hardness of Diorite is 6-7 and that of Wackestone is 2-3. The types of Diorite are Plagioclase Diorite and Quartz Diorite whereas types of Wackestone are Marl, Shale and Argillite. 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 Wackestone is white. The specific heat capacity of Diorite is 0.84 kJ/Kg K and that of Wackestone is 0.39 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 Wackestone is heat resistant, impact resistant.
