WebA subduction zone is a region of the earth's crust where one tectonic plate moves under another tectonic plate; oceanic crust gets recycled back into the mantle and continental crust gets created by the formation of arc magmas. WebIron (Fe) is one of the most abundant rock-forming elements, constituting about 5% of the Earth's crust. It is the fourth most abundant element after oxygen, silicon and aluminium and, after aluminium, the most abundant and widely distributed metal.
To be considered a common rock-forming mineral, a mineral must: A) be one of the most abundant minerals in Earths crust; B) be one of the original minerals present at the time of a crustal rocks formation; and, C) be an important mineral in determining a rocks classification.
