Formation

Formation
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 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 vs Diabase Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Anthracite and Diabase Reserves. Anthracite is a type of sedimentary rock which is hard and is variety of coal that has high luster. Diabase is a fine-grained igneous rock which is composed mostly of pyroxene and feldspar. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Anthracite vs Diabase information and Anthracite vs Diabase characteristics in the upcoming sections.

Anthracite vs Diabase 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. Anthracite vs Diabase characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Anthracite and Properties of Diabase. Learn more about Anthracite vs Diabase in the next section. The interior uses of Anthracite include Not yet used whereas the interior uses of Diabase include Countertops, Decorative aggregates, Homes, Interior decoration and Kitchens. Due to some exceptional properties of Anthracite and Diabase, they have various applications in construction industry. The uses of Anthracite in construction industry include Cement manufacture, For road aggregate, Making natural cement, Steel production and that of Diabase include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate.

More about Anthracite and Diabase

Here you can know more about Anthracite and Diabase. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Anthracite and Diabase consists of mineral content and compound content. The mineral content of Anthracite includes Calcite, Clay, Clay Minerals and mineral content of Diabase includes Augite, Chlorite, Olivine, Plagioclase, Pyroxene, Pyrrhotite, Serpentine. You can also check out the list of all Metamorphic Rocks. When we have to compare Anthracite vs Diabase, the texture, color and appearance plays an important role in determining the type of rock. Anthracite is available in black, brown, dark brown, grey, light to dark grey colors whereas, Diabase is available in dark grey to black colors. Appearance of Anthracite is Veined or Pebbled and that of Diabase is Vesicular. Properties of rock is another aspect for Anthracite vs Diabase. The hardness of Anthracite is 1-1.5 and that of Diabase is 7. The types of Anthracite are Semi-anthracite and Meta-anthracite whereas types of Diabase are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Anthracite and Diabase is black. The specific heat capacity of Anthracite is 1.32 kJ/Kg K and that of Diabase is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Anthracite is heat resistant, water resistant whereas Diabase is heat resistant, impact resistant, pressure resistant, wear resistant.
