Definition
Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight
A ganister is a hard, fine-grained quartzose sandstone or orthoquartzite which is basically used in the manufacture of silica brick typically used to line furnaces and is a type of sedimentary rocks.
Origin
Southern Alps, France
England
Discoverer

Unknown
Etymology
From French, from the name of Dolomieu (1750–1801), the French geologist who discovered the rock
From gan′is-ter i.e a hard, close-grained siliceous stone, often forming the stratum which underlies a coal-seam

Formation
Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.
Ganisters are formed by the destruction of easily weathered minerals mainly feldspar, within the surface horizon of soil by soil-forming processes.

Dolomite vs Ganister 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 Ganister characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Dolomite and Properties of Ganister. Learn more about Dolomite vs Ganister in the next section. The interior uses of Dolomite include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Ganister include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration. Due to some exceptional properties of Dolomite and Ganister, 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 Ganister include Cement manufacture, Construction aggregate, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar.
More about Dolomite and Ganister
Here you can know more about Dolomite and Ganister. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Dolomite and Ganister consists of mineral content and compound content. The mineral content of Dolomite includes Clay Minerals, Pyrite, Quartz, Sulfides and mineral content of Ganister includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Dolomite vs Ganister, 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, Ganister is available in beige, black, brown, colourless, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors. Appearance of Dolomite is Glassy or Pearly and that of Ganister is Rough. Properties of rock is another aspect for Dolomite vs Ganister. The hardness of Dolomite is 3.5-4 and that of Ganister is 6-7. The types of Dolomite are Boninite and Jasperoid whereas types of Ganister 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 Ganister is white. The specific heat capacity of Dolomite is 0.92 kJ/Kg K and that of Ganister is 0.92 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 Ganister is heat resistant, impact resistant, pressure resistant.
