Definition
Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight
Diamictite is a sedimentary rock that consists of non-sorted to poorly sorted terrigenous sediment containing particles that range in size from clay to boulders, suspended in a matrix of mudstone or sandstone

Features
Host Rock for Lead, Traps for subsurface fluids like Oil and Natural Gas., Zinc and Copper Deposits
Host Rock for Lead, Is one of the oldest rock
Archaeological Significance
Formation
Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.
Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.

Dolomite vs Diamictite 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. Dolomite vs Diamictite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Dolomite and Properties of Diamictite. Learn more about Dolomite vs Diamictite in the next section. The interior uses of Dolomite include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Diamictite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Dolomite and Diamictite, they have various applications in construction industry. The uses of Dolomite in construction industry include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories, Production of glass and ceramics, Serves as an oil and gas reservoir rock and that of Diamictite include As dimension stone, Construction aggregate, For road aggregate, Landscaping, Roadstone.
More about Dolomite and Diamictite
Here you can know more about Dolomite and Diamictite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Dolomite and Diamictite consists of mineral content and compound content. The mineral content of Dolomite includes Clay Minerals, Pyrite, Quartz, Sulfides and mineral content of Diamictite includes Calcite, Clay, Feldspar, Micas, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Dolomite vs Diamictite, the texture, color and appearance plays an important role in determining the type of rock. Dolomite is available in black, brown, green, grey, pink, white colors whereas, Diamictite is available in brown, buff colors. Appearance of Dolomite is Glassy or Pearly and that of Diamictite is Banded. Properties of rock is another aspect for Dolomite vs Diamictite. The hardness of Dolomite is 3.5-4 and that of Diamictite is 2-3. The types of Dolomite are Boninite and Jasperoid whereas types of Diamictite are Bedded Diamictite and Laminated Diamictite. 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 Diamictite is light to dark brown. The specific heat capacity of Dolomite is 0.92 kJ/Kg K and that of Diamictite is 0.75 kJ/Kg K. 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 Diamictite is heat resistant, impact resistant.
