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
Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers called coal beds

Etymology
From its mineral and compound content and its relation with Basalt and Andesite rock
From the Old English term col, which has meant mineral of fossilized carbon since the 13th century

Formation
Basaltic Trachandesite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
Coal forms from the accumulation of plant debris in a swamp environment which is buried by sediments such as mud or sand and then compacted to form coal.

Basaltic Trachyandesite vs Coal 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 Coal characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Basaltic Trachyandesite and Properties of Coal. Learn more about Basaltic Trachyandesite vs Coal in the next section. The interior uses of Basaltic Trachyandesite include Floor tiles, Homes, Hotels and Kitchens whereas the interior uses of Coal include Not yet used. Due to some exceptional properties of Basaltic Trachyandesite and Coal, 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 Coal include Cement manufacture, For road aggregate, Making natural cement, Steel production.
More about Basaltic Trachyandesite and Coal
Here you can know more about Basaltic Trachyandesite and Coal. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Basaltic Trachyandesite and Coal consists of mineral content and compound content. The mineral content of Basaltic Trachyandesite includes Olivine, Plagioclase, Pyroxene and mineral content of Coal includes Analcime, Apatite, Barite, Calcite, Chalcopyrite, Chlorite, Chromite, Clausthalite, Clay Minerals, Crandallite Group, Dolomite, Feldspar, Galena, Gypsum, Marcasite, Muscovite or Illite, Pyrite, Quartz, Siderite, Sphalerite, Zircon. You can also check out the list of all Igneous Rocks. When we have to compare Basaltic Trachyandesite vs Coal, 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, Coal is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Basaltic Trachyandesite is Dull and Soft and that of Coal is Veined or Pebbled. Properties of rock is another aspect for Basaltic Trachyandesite vs Coal. The hardness of Basaltic Trachyandesite is 6 and that of Coal is 1-1.5. 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 Coal are Peat, Lignite, Sub-Bituminous Coal, Bituminous Coal, Anthracite, Graphite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Basaltic Trachyandesite is white to grey while that of Coal is black. The specific heat capacity of Basaltic Trachyandesite is 0.84 kJ/Kg K and that of Coal is 1.32 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Basaltic Trachyandesite is heat resistant, pressure resistant, wear resistant whereas Coal is heat resistant.
