5 Formation

5.1 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.

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

Anthracite vs Scoria 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 Scoria Reserves. Anthracite is a type of sedimentary rock which is hard and is variety of coal that has high luster. Scoria is a dark-colored extrusive igneous rock with abundant round bubble-like cavities. 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 Scoria information and Anthracite vs Scoria characteristics in the upcoming sections.
