Definition
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
Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight
Origin
Unknown
Southern Alps, France

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

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

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