| 中文摘要: |
| 斑岩铜矿和矽卡岩铜矿在秘鲁有重要的成矿地位,秘鲁东南部古近系安达维拉斯-亚乌里(Andahuaylas-Yauri)斑岩-矽卡岩铜钼成矿带是最近十几年来铜钼多金属有重大找矿突破的成矿带。成矿带位于秘鲁安第斯山脉腹地,受纳兹卡板块(Nazca Plate)向南美大陆板块俯冲的影响,地表拆离断层与成矿作用关系密切,说明成矿期处于伸展构造环境。该成矿带在空间上岩体内的斑岩型和接触带附近的矽卡岩型及围岩中的岩浆热液型矿床“三位一体”。研究安达维拉斯-亚乌里斑岩-矽卡岩铜钼成矿带的空间、时间和成矿规律,对指导在区域内和具有同样成矿地质条件地区寻找斑岩-矽卡岩铜钼多金属矿有指导意义。 |
| 英文摘要: |
| Porphyry copper deposits and skarn copper deposits have important metallogenic status in Peru. The PaleogeneAndahuaylas-yauri porphyry-skarn Cu Mo metallogenic belt in southeastern Peru is a major metallogenic belt in copper molybdenum polymetallic exploration in recent ten years. The metallogenic belt is located in the subduction zone of the Nazca Plate towards the South American continental plate in Paleogene. The surface detachment faults are closely related to mineralization, indicating that the metallogenic period was in an extensional tectonic environment. In space, the porphyry type in the magmatic rock body, the skarn type near the contact zone and the magmatic hydrothermal deposit in the surrounding rock are “Trinity”. The study on the space, time and metallogenic regularity of Andaveras-Yauri porphyry skarn Cu Mo metallogenic belt is of great significance to the exploration of porphyry-skarn Cu-Mo polymetallic deposits in the region and in the areas with the same metallogenic geological conditions. |
