| 中文摘要: |
| 鞍山—本溪地区是我国前寒武系条带状铁建造型铁矿的主要分布区,已探明资源储量约占全国同类型铁矿已探明资源储量的40%,是我国最大的铁矿石资源基地。通过铁矿带对比,依据变质岩石组合、原岩建造以及铁矿地质特征,将鞍山—本溪地区含铁变质地层划分为茨沟组、大峪组和西鞍山组。与绿岩带柱状剖面对比,茨沟组和大峪沟组相当于绿岩带中部岩系的上部岩组,西鞍山组相当于绿岩带上部沉积岩系。 |
| 英文摘要: |
| Anshan-Benxi area is the main distribution area of Precambrian BIF type iron ore deposits.Reserve of these deposits in Anshan-Benxi area is about 40% of the total of the same type iron ore deposits all over china thus it is the biggest iron resource base of china.Based on correlation of the iron ore belts,metamorphic rock association,reconstructian of the original rocks and the iron ore deposit geology the iron ore-bearing metamorphic rock in the area could be divided into Cigou Fm,Dayugou Fm West Anshan Fm.The former two Fm can be correlated to the upper rock Fm of the middle green stone belt rock sequence the latter one to the sedimentary rock of the upper green stone belt. |
