| 中文摘要: |
| 岩坡铜矿区位于墨江—绿春铜多金属成矿带的南段,是区内典型的玄武岩型铜矿之一,通过综合分析矿区的地质特征、地球化学特征,认为铜矿体受地层、岩性、构造的控制。该区的玄武岩属于陆相喷发的碱性玄武岩,玄武岩的含铜背景高,为成矿提供了主要的物质来源,铜矿化产于玄武岩的喷发旋回中,受到后期的热液改造富集,矿区获得的地球化学异常强度高,规模大,浓集中心明显,反映出该区是寻找铜、铅、锌、金的有利地段。 |
| 英文摘要: |
| The Yanpo copper deposit located in southern part of Mojiang-Lüchun copper polymetallic metallogenic belt, is one of typical basalt type copper deposit in the region. Through the comprehensive analysis of geological characteristics and geochemical characteristics of the deposit area, it is concluded that the copper deposit is controlled by the stratum, lithology and structure. The basalt in the deposit area belongs to alkaline basalt which was formed by continental eruption. There is high copper content in the basalt which provides main metallogenic material source. The copper mineralization occurs in the eruption cycle, then enriched by the late hydrothermal transformation. The intensive and large scale geochemical anomalies, with obvious cluster center indicate that there are favorable target areas for prospecting copper, lead, zinc and gold deposits. |
