| 摘 要： | 阿根廷金矿资源丰富,西部是安第斯金成矿带的重要组成部分,勘查开发和利用程度较低,具有较大的找矿和开发潜力。根据区域构造演化和金矿成矿规律,梳理了阿根廷金成矿地质背景,厘定了金成矿作用与构造-岩浆事件的关系。将阿根廷金成矿时代划分为4个集中时期,阐述了各成矿期的主要金矿床类型,分析了其空间分布规律,划分出5个成矿带和15个矿集区,总结了各矿集区的主控矿因素,为进一步确定阿根廷金矿资源潜力和找矿方向奠定了基础。

| Abstract: | Argentina has rich gold resources which constitute the important part of the Andean gold metallogenic belt. However, the level of exploration and utilization of gold is low, and hence the exploration and development have great potential. Based on the history of regional tectonic evolution, the authors have reviewed the geological background of gold mineralization and investigated the relationship between the gold mineralization and tectono-magmatic events. According to methods mentioned above, the gold mineralization epochs, during which the main deposit types were formed, are divided into 4 concentrated periods. The spatial distribution of Argentina''s gold deposits was summarized and divided into 5 gold metallogenic belts and 15 gold districts based on the summarizing of the main ore-controlling factors with the purpose of laying a solid foundation for discussing the gold resource potential and prospecting direction in Argentina. |
