Formation
Anthracite forms from the accumulation of plant debris in a swamp environment. When plant debris dies and falls into the swamp, the standing water of the swamp protects it from decay.
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 Anthracite and Wackestone
Here you can know more about Anthracite and Wackestone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Anthracite and Wackestone consists of mineral content and compound content. The mineral content of Anthracite includes Calcite, Clay, Clay Minerals 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 Metamorphic Rocks. When we have to compare Anthracite vs Wackestone, the texture, color and appearance plays an important role in determining the type of rock. Anthracite is available in black, brown, dark brown, grey, light to dark grey colors whereas, Wackestone is available in black, blue, brown, green, grey, orange, red, white, yellow colors. Appearance of Anthracite is Veined or Pebbled and that of Wackestone is Rough and Dull. Properties of rock is another aspect for Anthracite vs Wackestone. The hardness of Anthracite is 1-1.5 and that of Wackestone is 2-3. The types of Anthracite are Semi-anthracite and Meta-anthracite 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 Anthracite is black while that of Wackestone is white. The specific heat capacity of Anthracite is 1.32 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.Anthracite is heat resistant, water resistant whereas Wackestone is heat resistant, impact resistant.
