Formation
Basalt forms when lava reaches the Earth's surface near an active volcano. The temperature of lava is between 1100 to 1250° C when it gets to the surface.
Anthracite forms from the accumulation of plant debris in a swamp environment. When plant debris dies and falls into the swamp, the standing water of the swamp protects it from decay.

Basalt vs Anthracite 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. Basalt vs Anthracite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Basalt and Properties of Anthracite. Learn more about Basalt vs Anthracite in the next section. The interior uses of Basalt include Floor tiles, Homes, Hotels and Kitchens whereas the interior uses of Anthracite include . Due to some exceptional properties of Basalt and Anthracite, they have various applications in construction industry. The uses of Basalt in construction industry include Arrowheads, As dimension stone, Cobblestones, Cutting tool, Rail track ballast, Roadstone and that of Anthracite include Cement manufacture, For road aggregate, Making natural cement, Steel production.
More about Basalt and Anthracite
Here you can know more about Basalt and Anthracite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Basalt and Anthracite consists of mineral content and compound content. The mineral content of Basalt includes Olivine, Plagioclase, Pyroxene and mineral content of Anthracite includes Calcite, Clay, Clay Minerals. You can also check out the list of all Igneous Rocks. When we have to compare Basalt vs Anthracite, the texture, color and appearance plays an important role in determining the type of rock. Basalt is available in black, brown, light to dark grey colors whereas, Anthracite is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Basalt is Dull and Soft and that of Anthracite is Veined or Pebbled. Properties of rock is another aspect for Basalt vs Anthracite. The hardness of Basalt is 6 and that of Anthracite is 1-1.5. The types of Basalt are Alkaline Basalt, Boninite, High Alumina Basalt, Mid Ocean Ridge Basalt (MORB), Tholeiitic Basalt, Basaltic trachyandesite, Mugearite and Shoshonite whereas types of Anthracite are Semi-anthracite and Meta-anthracite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Basalt is white to grey while that of Anthracite is black. The specific heat capacity of Basalt is 0.84 kJ/Kg K and that of Anthracite 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.Basalt is heat resistant, pressure resistant, wear resistant whereas Anthracite is heat resistant, water resistant.
