Formation

Formation
Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.   
Taconite is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. When the river reaches a lake or sea, its load of transported rocks settles or deposits at the bottom of sea or lake.

Scoria vs Taconite 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 Taconite Reserves. Scoria is a dark-colored extrusive igneous rock with abundant round bubble-like cavities. Taconite is a low-grade iron ore which belongs to sedimentary rock and containing about 27% iron and 51% silica. 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 Taconite information and Scoria vs Taconite characteristics in the upcoming sections.
