    Over a period of a billion years, huge deposits of iron ores were laid at the bottom of the sea. This activity took place between 3.5 and 2.5 billion years ago. Iron ores mined today in the United States, Australia, and South Africa, are part of the huge deposits laid down at that time. Once the oceans were swept clean of iron, then the oxygen could begin to

  • Classification of ore deposits - SlideShare

    However, genetic classifications are very dangerous, as they assume that we know the origin of the ore deposit, which, in many cases, we don't! They are also subject to change as scientists revise their models for the genesis of an ore deposit. This leaves us with using the "environment" of the ore body or its "geologic setting" as perhaps the best criterion for the classification of

    Most deposits of iron ore in the world are found in rocks known as banded iron formations (BIFs). These are sedimentary rocks that have alternating layers of iron-rich minerals and a fine-grained silica rock called chert. Many of the banded iron formations that are being mined today were formed millions of years ago. About 3000 million years ago there was no or very little

  • GEOLOGY AND GEOCHEMISTRY OF HIGH-GRADE IRON- ORE DEPOSITS

    Despite the economic importance of these ore bodies, their origin has not been the subject of detailed research since the 1960s. The early studies concluded that the high-grade iron- ore deposits were formed during the Mesozoic, due to the downward percolation of groundwater and subsequent leaching of silica, forming enriched residual iron-ore deposits (Stubbins et al., 1961; Gross, 1968
