Field Relationship among the Three Iron Ore Groups of Iron

Iron formations are economically important sedimentary rocks that are most common in Precambrian sedimentary successions. Iron formations host the majority of the world’s economic Fe ore, which has fostered extensive research on their origin, depositional setting, and spatial and temporal distribution. The supracrustal including banded iron formation and iron ore of Precambrian age constitute three discrete geographic segments along the periphery of the North Odisha Iron Ore Craton (NOIOC) (Figu

Iron Ore: Sedimentary Rock - Pictures, Definition & More

18.08.2020 · How Does Iron Ore Form? Nearly all of Earth's major iron ore deposits are in rocks that formed over 1.8 billion years ago. At that time Earth's oceans contained abundant dissolved iron and almost no dissolved oxygen. The iron ore deposits began forming when the first organisms capable of photosynthesis began releasing oxygen into the waters.
