jernmalmforekomster
Jernmalmforekomster are geological deposits containing economically significant concentrations of iron ore. These deposits form through various geological processes over millions of years, primarily involving the accumulation and alteration of iron-bearing minerals. The most common iron-bearing minerals found in these deposits include hematite (Fe2O3), magnetite (Fe3O4), goethite (FeO(OH)), and limonite (a mixture of hydrated iron oxides). The concentration of iron within these deposits determines their economic viability for extraction.
The formation of jernmalmforekomster is often linked to Precambrian banded iron formations (BIFs), which are layered
Historically, jernmalmforekomster have been crucial for the development of human civilization, providing the raw material for
