    In the Hamersley Province of the Pilbara craton (Western Australia), the Archean Marra Mamba and earliest Proterozoic Brockman Iron Formations host two main ore types: martite–microplaty hematite (M-mph; >64 wt% Fe) and martite-goethite (M-G; ~62 wt% Fe; Ramanaidou and Wells, 2014), where "martite" refers to the pseudomorphic replacement of magnetite by hematite.


  • Hemarate | Iron Supplement - Unilab

    Hemarate contains iron, Vitamins B 6 and B 12. These nutrients are necessary for healthy blood, synthesis of hemoglobin (an oxygen containing protein which gives blood its red color) and to prevent iron-deficiency anemia (IDA). IDA is one of the most prevalent nutritional problems in developing countries including the Philippines.
