Geology Of Iron Ore Deposits In Teas Grinding Mill

Nearly all of Earth39s major iron ore deposits are in rocks that formed over 1.8 billion years ago. At that time Earth39s 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.
