Archaeological Significance
Formation
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.
Shonkinites are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.

More about Wackestone and Shonkinite
Here you can know more about Wackestone and Shonkinite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Wackestone and Shonkinite consists of mineral content and compound content. The mineral content of Wackestone includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz and mineral content of Shonkinite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Wackestone vs Shonkinite, the texture, color and appearance plays an important role in determining the type of rock. Wackestone is available in black, blue, brown, green, grey, orange, red, white, yellow colors whereas, Shonkinite is available in brown, buff, cream, green, grey, pink, white colors. Appearance of Wackestone is Rough and Dull and that of Shonkinite is Banded and Foilated. Properties of rock is another aspect for Wackestone vs Shonkinite. The hardness of Wackestone is 2-3 and that of Shonkinite is 5.5-6. The types of Wackestone are Marl, Shale and Argillite whereas types of Shonkinite are Igneous rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Wackestone and Shonkinite is white. The specific heat capacity of Wackestone is 0.39 kJ/Kg K and that of Shonkinite 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.Wackestone is heat resistant, impact resistant whereas Shonkinite is heat resistant, impact resistant, wear resistant.
