    Gold-rich banded iron formations – Ahead of the Herd

    Mar 01, 2019 While most banded iron formations are composed of at least 15% iron (Fe), some BIFs are associated with non-Fe resources, including gold deposits in greenstone terranes – fragments of crust broken off from tectonic plates. Research suggests that black shales found in banded iron formations played a role in the creation of gold deposits

    Feb 27, 2017 If you follow mining, you also know that the banded iron formations are one of the most important sources of iron in the modern world – two of the largest producers, Australia and China, have enormous reserves of iron stored within their banded iron formations. Outcrops of banded iron are found all over the world. In this post, we’ll take a look at how this distinctive

    Apr 29 2014. Banded iron formations (BIFs) are sedimentary rocks, characterized by the presence of alternating layers of iron-rich minerals - known as magnetite - and amorphous silica-rich rocks - known as cherts. Each layer is relatively thin with varying levels of thickness, measuring from a millimeter up to several centimeters

    Aug 11, 2013 All the world’s Banded Iron Formations appear to have been formed by an unusual, one-off event. With many types of mineralisation – we can see the process occurring today – for example active volcanoes show us mines in the making, as does undersea hydrothermal activity. Banded iron formations (BIFs) are different – they were all formed at
