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.
Pegmatite rock is holocrystalline, intrusive igneous rock which is formed by partial melting and dewatering during the process of metamorphism.

More about Wackestone and Pegmatite
Here you can know more about Wackestone and Pegmatite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Wackestone and Pegmatite 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 Pegmatite includes Apatite, Beryl, Feldspar, Fluorite, Garnet, Lepidolite, Quartz, Silica, Spodumene, Topaz. You can also check out the list of all Sedimentary Rocks. When we have to compare Wackestone vs Pegmatite, 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, Pegmatite is available in black, brown, cream, green, grey, pink, red, rust, silver, white, yellow colors. Appearance of Wackestone is Rough and Dull and that of Pegmatite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Wackestone vs Pegmatite. The hardness of Wackestone is 2-3 and that of Pegmatite is 7. The types of Wackestone are Marl, Shale and Argillite whereas types of Pegmatite are Granite Pegmatite, Gabbro Pegmatite and Diorite Pegmatite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Wackestone and Pegmatite is white. The specific heat capacity of Wackestone is 0.39 kJ/Kg K and that of Pegmatite is 0.79 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 Pegmatite is heat resistant, impact resistant, pressure resistant.
