Formation
Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.
Flint is formed by the decomposition and compaction of various organisms such as sponges and diatoms under the water.

More about Dolomite and Flint
Here you can know more about Dolomite and Flint. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Dolomite and Flint consists of mineral content and compound content. The mineral content of Dolomite includes Clay Minerals, Pyrite, Quartz, Sulfides and mineral content of Flint includes Silicon. You can also check out the list of all Sedimentary Rocks. When we have to compare Dolomite vs Flint, 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, Flint is available in black, brown, green, grey, red, white colors. Appearance of Dolomite is Glassy or Pearly and that of Flint is Glassy or Pearly. Properties of rock is another aspect for Dolomite vs Flint. The hardness of Dolomite is 3.5-4 and that of Flint is 7. The types of Dolomite are Boninite and Jasperoid whereas types of Flint 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 Flint is white. The specific heat capacity of Dolomite is 0.92 kJ/Kg K and that of Flint is 0.74 kJ/Kg K.
