| 中文摘要:文章在分析云南东川杉木箐铁铜矿成矿地质背景和地质特征基础上, 根据邻区东川式、稀矿山式铁铜矿的成矿条件和岩隆构造、重磁同现异常、化探异常、矿化等找矿信息, 结合省地勘基金项目勘查的最新成果, 对勘查区的找矿潜力进行了分析和研究。认为其成矿特征、物化探异常与落因铁铜矿带类似, 圈定零公里至小坡和二百二至新寨等2条重磁同现异常带(岩隆构造带)及附近区段为有利找矿靶区, 推测深部具有中-大型矿床规模的找矿潜力。 |

| Geological Characteristics and Ore-prospecting Potential of the Shanmuqing Fe-Cu Deposit in Dongchuan, Yunnan Province |

| Abstract:Based on an analysis of ore-forming geological background and geological characteristics of the Shanmuqing Fe-Cu deposit in Dongchuan of Yunnan Province and using the information in such aspects as the metallogenic conditions of Fe-Cu deposit of Dongchuan model, the Xikuangshan model of the neighboring area, the dome structure, the gravity-magnetic anomaly, the geochemical anomaly and the mineralization, in combination with the newest results in geological exploration of Yunnan Province, the authors analyzed and studied the ore-prospecting potential of the exploration area. Considering that its metallogenic characteristics and geophysical-geochemical anomaly are similar to those of the Luoyin Fe-Cu ore belt, the authors delineated two gravity-magnetic anomaly belts of Linggongli-Xiaopo and Erbaier-Xinzhai and their nearly areas as prospecting targets. It is inferred that there exists great prospecting potential in search for middle-large ore bodies at the depth. |
