Definition
Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight
Shoshonite is a basaltic rock, properly a potassic trachyandesite, composed of olivine, augite and plagioclase phenocrysts in a groundmass with calcic plagioclase and sanidine and some dark-colored volcanic glass

Formation
Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.
Shoshonite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

More about Dolomite and Shoshonite
Here you can know more about Dolomite and Shoshonite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Dolomite and Shoshonite consists of mineral content and compound content. The mineral content of Dolomite includes Clay Minerals, Pyrite, Quartz, Sulfides and mineral content of Shoshonite includes Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Dolomite vs Shoshonite, 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, Shoshonite is available in brown- black, dark brown colors. Appearance of Dolomite is Glassy or Pearly and that of Shoshonite is Dull. Properties of rock is another aspect for Dolomite vs Shoshonite. The hardness of Dolomite is 3.5-4 and that of Shoshonite is 6. The types of Dolomite are Boninite and Jasperoid whereas types of Shoshonite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Dolomite is white while that of Shoshonite is white to grey. The specific heat capacity of Dolomite is 0.92 kJ/Kg K and that of Shoshonite 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 Shoshonite is heat resistant, pressure resistant.
