| 摘 要： | 前寒武纪条带状硅铁建造(BIF)是世界,也是中国最重要的铁矿资源类型,无论是储量,还是开采量,均居首位.前寒武纪条带状硅铁建造是地球早期特有的化学沉积建造类型,广泛分布于太古代—早元古代(3.2～1.8 Ga),记录了地球早期大气和海洋的化学成分、氧化还原状态及演化,是广大地质工作者长期关注的焦点之一.在国外,与BIF... |

| Abstract: | The Precambrian Banded Iron Formations(BIF) are the most important iron resource both in China and abroad,whether in the exploratory reserves or in the quantity of the exploitation.BIF were also the special geochemical sediments in the early earth history which recorded the composition and the redoxomorphic stage of the contemporary atmosphere and the ocean as well as their evolution.The paleo-weathering crust of BIF,which is the most enriched iron ore,is widely distributed in the world.However,this type of... |
