Formation
Diabase forms when molten igneous rock is squeezed up into a vertical crack in other rocks, the crack is usually forced apart and the molten rock cools in the space to form a tabular igneous intrusion cutting across the surrounding rocks and is known as a dike.
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.

Diabase 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. Diabase vs Anthracite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Diabase and Properties of Anthracite. Learn more about Diabase vs Anthracite in the next section. The interior uses of Diabase include Countertops, Decorative aggregates, Homes, Interior decoration and Kitchens whereas the interior uses of Anthracite include . Due to some exceptional properties of Diabase and Anthracite, they have various applications in construction industry. The uses of Diabase in construction industry include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate and that of Anthracite include Cement manufacture, For road aggregate, Making natural cement, Steel production.
More about Diabase and Anthracite
Here you can know more about Diabase and Anthracite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diabase and Anthracite consists of mineral content and compound content. The mineral content of Diabase includes Augite, Chlorite, Olivine, Plagioclase, Pyroxene, Pyrrhotite, Serpentine 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 Diabase vs Anthracite, the texture, color and appearance plays an important role in determining the type of rock. Diabase is available in dark grey to black colors whereas, Anthracite is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Diabase is Vesicular and that of Anthracite is Veined or Pebbled. Properties of rock is another aspect for Diabase vs Anthracite. The hardness of Diabase is 7 and that of Anthracite is 1-1.5. The types of Diabase are Dolerite 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 Diabase and Anthracite is black. The specific heat capacity of Diabase 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.Diabase is heat resistant, impact resistant, pressure resistant, wear resistant whereas Anthracite is heat resistant, water resistant.
