| 摘 要： | 印支－燕山期构造－岩浆热液活动，对秦岭－祁连造山带的区域成矿控制与影响作用十分显著，主要表现在该期北东向构造－岩浆活动不仅控制了金等矿产的形成，而且使先期形成的铜，铅锌等矿产发生了较强烈的改造和富集作用，该期北东向构造带与先期的北西、近东西向构造或含矿层交汇叠加部位，是形成大型－超大型矿床的重要条件。文章对秦岭－祁连造山带印支－燕山期构造－岩浆活动带的发育特征及其对大型－超大型矿床的控制与影响等进行了初步分析与探讨，提出了本区新一轮矿产勘查研究对策与思路。 |

| Abstract: | It is obvious that the Indosinian-Yanshanian tectono-magmatic activities controlled and affected the ore-forming process of the Qinling-Qilian orogenic belt. This finds expression in the fact that the Indosinian-Yanshanian NE-trending structures not only controlled the mineralization of gold and other metallic minerals but also caused the considerable reformation and enrichment of the earlier-formed copper, zinc, lead and other minerals. Where the NE-trending structures intersected or are superimposed on the earlier-formed NW- and nearly EW-trending structures or ore-bearing formations, the large and superlarge mineral deposits are likely to be formed. In this paper, the characteristics of the Indosinian-Yanshanian tectono-magmatic belt which controlled and affected the formation of large-superlarge mineral deposits are analyzed and discussed, and new measures and thinking are put forward for carrying out a new round of mineral exploration in this region. |
