Definition
Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight
  
Basaltic Trachyandesite is an extrusive igneous rock which is a type of Basalt rock and is formed by the rapid cooling of basaltic lava exposed at or very near the Earth's surface
  
History
  
  
Origin
Southern Alps, France

Etymology
From French, from the name of Dolomieu (1750–1801), the French geologist who discovered the rock
  
From its mineral and compound content and its relation with Basalt and Andesite rock

Formation
Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.
  
Basaltic Trachandesite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.

Dolomite vs Basaltic Trachyandesite 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 Basaltic Trachyandesite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Dolomite and Properties of Basaltic Trachyandesite. Learn more about Dolomite vs Basaltic Trachyandesite in the next section. The interior uses of Dolomite include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Basaltic Trachyandesite include Floor tiles, Homes, Hotels and Kitchens. Due to some exceptional properties of Dolomite and Basaltic Trachyandesite, 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 Basaltic Trachyandesite include As dimension stone, Cobblestones, Rail track ballast, Roadstone.
More about Dolomite and Basaltic Trachyandesite
Here you can know more about Dolomite and Basaltic Trachyandesite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Dolomite and Basaltic Trachyandesite consists of mineral content and compound content. The mineral content of Dolomite includes Clay Minerals, Pyrite, Quartz, Sulfides and mineral content of Basaltic Trachyandesite includes Olivine, Plagioclase, Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Dolomite vs Basaltic Trachyandesite, 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, Basaltic Trachyandesite is available in black, brown, light to dark grey colors. Appearance of Dolomite is Glassy or Pearly and that of Basaltic Trachyandesite is Dull and Soft. Properties of rock is another aspect for Dolomite vs Basaltic Trachyandesite. The hardness of Dolomite is 3.5-4 and that of Basaltic Trachyandesite is 6. The types of Dolomite are Boninite and Jasperoid whereas types of Basaltic Trachyandesite are Alkaline Basalt, Boninite, High Alumina Basalt, Mid Ocean Ridge Basalt (MORB), Tholeiitic Basalt, Basaltic trachyandesite, Mugearite and Shoshonite. 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 Basaltic Trachyandesite is white to grey. The specific heat capacity of Dolomite is 0.92 kJ/Kg K and that of Basaltic Trachyandesite is 0.84 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 Basaltic Trachyandesite is heat resistant, pressure resistant, wear resistant.
