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.
  
Dunite is a plutonic ultramafic igneous rock consisting almost m olivine. It can be formed in two ways.

Wackestone vs Dunite Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Wackestone vs Dunite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Wackestone and Properties of Dunite. Learn more about Wackestone vs Dunite in the next section. The interior uses of Wackestone include Decorative aggregates, Flooring and Interior decoration whereas the interior uses of Dunite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Wackestone and Dunite, they have various applications in construction industry. The uses of Wackestone in construction industry include Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar and that of Dunite include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar.
More about Wackestone and Dunite
Here you can know more about Wackestone and Dunite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Wackestone and Dunite 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 Dunite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Wackestone vs Dunite, 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, Dunite is available in dark greenish - grey colors. Appearance of Wackestone is Rough and Dull and that of Dunite is Rough and Shiny. Properties of rock is another aspect for Wackestone vs Dunite. The hardness of Wackestone is 2-3 and that of Dunite is 3.5-4. The types of Wackestone are Marl, Shale and Argillite whereas types of Dunite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Wackestone and Dunite is white. The specific heat capacity of Wackestone is 0.39 kJ/Kg K and that of Dunite is 1.25 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 Dunite is heat resistant, pressure resistant, wear resistant.
