Definition
Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight
Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix
Origin
Southern Alps, France
Italy
Discoverer
Dolomieu
Unknown
Etymology
From French, from the name of Dolomieu (1750–1801), the French geologist who discovered the rock
From Latin conglomeratus, to roll together, i.e. from com together + glomerare to gather into a ball, from glomus (genitive glomeris) a ball

Features
Host Rock for Lead, Traps for subsurface fluids like Oil and Natural Gas., Zinc and Copper Deposits
Clasts are smooth to touch, Is one of the oldest rock, Matrix variable
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.
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.

Dolomite vs Conglomerate 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 Conglomerate characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Dolomite and Properties of Conglomerate. Learn more about Dolomite vs Conglomerate in the next section. The interior uses of Dolomite include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Conglomerate include Decorative aggregates, Floor tiles and Homes. Due to some exceptional properties of Dolomite and Conglomerate, 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 Conglomerate include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Roadstone.
More about Dolomite and Conglomerate
Here you can know more about Dolomite and Conglomerate. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Dolomite and Conglomerate consists of mineral content and compound content. The mineral content of Dolomite includes Clay Minerals, Pyrite, Quartz, Sulfides and mineral content of Conglomerate includes Clay, Sand, Silica, Silt. You can also check out the list of all Sedimentary Rocks. When we have to compare Dolomite vs Conglomerate, 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, Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors. Appearance of Dolomite is Glassy or Pearly and that of Conglomerate is Shiny and Rounded. Properties of rock is another aspect for Dolomite vs Conglomerate. The hardness of Dolomite is 3.5-4 and that of Conglomerate is 2-3. The types of Dolomite are Boninite and Jasperoid whereas types of Conglomerate are Orthoconglomerate and Paraconglomerate. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Dolomite and Conglomerate is white. The specific heat capacity of Dolomite is 0.92 kJ/Kg K and that of Conglomerate 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 Conglomerate is heat resistant.
