Formation
Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.
Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.

More about Dolomite and Scoria
Here you can know more about Dolomite and Scoria. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Dolomite and Scoria consists of mineral content and compound content. The mineral content of Dolomite includes Clay Minerals, Pyrite, Quartz, Sulfides and mineral content of Scoria includes Apatite, Biotite, Calcite, Feldspar, Hematite, Hornblade, Ilmenite, Magnetite, Olivine, Pyroxene, Quartz, Silica. You can also check out the list of all Sedimentary Rocks. When we have to compare Dolomite vs Scoria, the texture, color and appearance plays an important role in determining the type of rock. Dolomite is available in black, brown, colourless, green, grey, pink, white colors whereas, Scoria is available in black, brown, dark grey to black, red colors. Appearance of Dolomite is Glassy or Pearly and that of Scoria is Glassy and Vesicular. Properties of rock is another aspect for Dolomite vs Scoria. The hardness of Dolomite is 3.5-4 and that of Scoria is 5-6. The types of Dolomite are Boninite and Jasperoid whereas types of Scoria are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Dolomite and Scoria is white. The specific heat capacity of Dolomite is 0.92 kJ/Kg K and that of Scoria is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Dolomite is heat resistant, pressure resistant, wear resistant whereas Scoria is heat resistant, impact resistant, pressure resistant, wear resistant.
