Top Gold-Bearing Banded Iron Formations (BIFs) of the World Some ancient BIFs don’t just host iron: they also trap gold where hydrothermal fluids altered iron-rich layers 1 Witwatersrand Basin, South Africa: world’s richest gold field 2 Yilgarn Craton, Western Australia: classic BIF-hosted lode gold 3 Lake Victoria Goldfields, Tanzania: sulfidized magnetite bands with gold 4 Zimbabwe Craton (Kwekwe, Gwanda) : pyrite-arsenopyrite-gold zones 5 Migori Belt, Kenya: BIF-hosted gold within folded Arch

About 2.6 billion years ago, life began to bloom on Earth. All complex life, including humans, developed over billions of years from tiny bacteria in Earth's young #Oceans. This rock, on display in #HintzeHall, records the moment that it all began: http://bit.ly/NHM-BIF-Film | Natural History Museum, London

This is a beautiful “Banded Iron Formation” It is “Red Jasper” with the beautiful swirling bands of iron and hematite ore. Once this stone is polished, the bands can become as shiny as a mirror. ❤️ هذا "تكوين حديدي مخطط" جميل. إنه "يشب أحمر" بأشرطة دوامية جميلة من الحديد وخام الهيماتيت. بمجرد صقل هذا الحجر، تصبح هذه الأشرطة لامعة كالمرآة. ❤️ | Omar Nacer
