Archaeological Significance
Formation
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.
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 Charnockite and Wackestone
Here you can know more about Charnockite and Wackestone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Charnockite and Wackestone consists of mineral content and compound content. The mineral content of Charnockite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz 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 Charnockite vs Wackestone, the texture, color and appearance plays an important role in determining the type of rock. Charnockite is available in black, grey, orange, pink, white colors whereas, Wackestone is available in black, blue, brown, green, grey, orange, red, white, yellow colors. Appearance of Charnockite is Veined or Pebbled and that of Wackestone is Rough and Dull. Properties of rock is another aspect for Charnockite vs Wackestone. The hardness of Charnockite is 6-7 and that of Wackestone is 2-3. The types of Charnockite are Enderbite 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 Charnockite and Wackestone is white. The specific heat capacity of Charnockite 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.Charnockite is heat resistant, wear resistant whereas Wackestone is heat resistant, impact resistant.
