| 摘 要： | 铜陵矿集区深部结构特征为该区大规模成岩成矿作用奠定了良好的基础,浅表已发现的矿床只是矿集区成矿系统的一部分。除此之外,深部还应有多个可以找寻的矿床(矿体)的富集空间。与成矿相关的花岗岩研究表明,铜陵矿集区可能存在与宁芜火山盆地同期的成岩成矿作用,是铜陵矿集区找矿的新方向。铜陵矿集区奥陶系灰岩中铜金矿化作用的初步研究表明,除传统矿床类型外,前泥盆纪地层中的成矿作用应该在今后的找矿工作中得到关注。覆盖区成矿预测初步研究表明,铜陵矿集区向斜核部及褶皱倾伏端等地段具有与已知典型矿床相似的成矿条件。铜陵矿集区的进一步找矿工作应该在上述地段运用矿田构造系统分析、深部地球物理探测和工程验证等方法逐步展开。 |

| Abstract: | The deep structure of Tongling ore concentration area established favorable basis for large-scale diagenesis and metallogenesis in this area where the shallow discoverable ore deposits are only part of the cluster metallogenic system.Added to this,there should be many enrichment spaces of deposits or ore bodies for searching in depth.The study of granite related to mineralization suggested that,the Tongling ore concentration area may exist diagenesis and metallogenesis during the same time with Ningwu volcanic basin,which is considered to be new direction for further ore searching.The elementary study of copper and gold mineralization in Ordovician limestone indicated that besides the traditional deposit types,the metallogenesis in pre-Devonian layers should be paid attention in the future of ore-searching.Study of metallogenic prediction in overlay area shows that the places in the core of syncline and the plunge of fold have the same metallogenic conditions with the known typical deposits.The further ore prospecting in Tongling ore concentration area should focus on the above prediction area using the methods of ore-field systematic analysis,deep geophysical survey and engineering verification. |
