Formation

Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.

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.

Scoria 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 Scoria and Diabase Reserves. Scoria is a dark-colored extrusive igneous rock with abundant round bubble-like cavities. 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 Scoria vs Diabase information and Scoria vs Diabase characteristics in the upcoming sections.

More about Scoria and Diabase

Here you can know more about Scoria and Diabase. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Scoria and Diabase consists of mineral content and compound content. The mineral content of Scoria includes Apatite, Biotite, Calcite, Feldspar, Hematite, Hornblade, Ilmenite, Magnetite, Olivine, Pyroxene, Quartz, Silica and mineral content of Diabase includes Augite, Chlorite, Olivine, Plagioclase, Pyroxene, Pyrrhotite, Serpentine. You can also check out the list of all Igneous Rocks. When we have to compare Scoria vs Diabase, the texture, color and appearance plays an important role in determining the type of rock. Scoria is available in black, brown, dark grey to black, red colors whereas, Diabase is available in dark grey to black colors. Appearance of Scoria is Glassy and Vesicular and that of Diabase is Vesicular. Properties of rock is another aspect for Scoria vs Diabase. The hardness of Scoria is 5-6 and that of Diabase is 7. The types of Scoria are Basaltic Scoria and Andesitic Scoria whereas types of Diabase are Dolerite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Scoria is white while that of Diabase is black. The specific heat capacity of Scoria is 0.84 kJ/Kg K and that of Diabase is 0.84 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Scoria is heat resistant, impact resistant, pressure resistant, wear resistant whereas Diabase is heat resistant, impact resistant, pressure resistant, wear resistant.
