| 摘 要： | 通过对长江中下游Fe-Cu-Au多金属重要成矿带的宁芜、大冶铁矿成矿模式和成矿地质背景的分析,按照成矿系列中缺位预测的原则,认为在宁芜盆地南段的岩体存在双层结构,与上层岩体有关的矿床为典型的"玢岩铁矿";深部下层岩体具有"大冶式"铁矿相似的成矿地质环境;在此基础上,提出了在宁芜玢岩铁矿下部有大冶式铁矿存在的认识,并构建了宁芜盆地南段"丰"字型成矿模式。认为采用"模式"类比、立体填图、综合物探方法进行综合探测将具有较好的找矿效果。

| Abstract: | Based on analysis of the metallogenetic models and ore geological settings of both the Ningwu-type and Daye-type iron deposits which are the most important deposit-types in the low-middle Yangtze Fe-Cu-Au polymetallic metallogenic belt,and on the vacant predication theory of metallogenic series,the authors suggest that the magmatic bodies occur as double-layers in the southern Ningwu basin and that the deep part of the southern Ningwu basin has ore-forming geological conditions similar to that the DaYe-type... |
