Iron rich sedimentary rocks WikipediaBIOGEOCHEMICAL AND ENVIRONMENTAL FACTORS IN Fe

Iron rich sedimentary rocks are sedimentary rocks which contain 15 or more iron However An example of a mineral in iron rich rock containing carbonates is siderite and an example of minerals in an iron rich rock containing silicate is chamosite The dominant minerals in the oxide facies are magnetite and hematiteA mixture of magnetite and siderite was formed in the presence of a N2 CO2 headspace Akaganeite was iron oxide goethite magnetite and hematite are
