摘要
广东省云浮硫铁矿属华南型块状硫化物矿床,为大型—超大型硫化物矿床,但其底部普遍存在的铅锌矿化层位未进行系统的地质勘查工作.本文在收集云浮硫铁矿大降坪矿区已有地质勘探资料的基础上,重点对F1 断裂和723倒转背斜构造附近的地球物理异常特征进行解释推断,认为F1 断裂异常带是寻找构造蚀变岩型铅锌矿的重要部位,723 倒转背斜轴部异常地段是寻找层间破碎带中的铅锌矿的有利部位.
Abstract
The Yunfu pyrite deposit in Guangdong belongs to the South China type massive sulfide deposit,which is a large-superlarge sulfide deposit,but no systematic geological exploration work has been carried out for the Pb-Zn mineralization layer at the bottom of the deposit.On the basis of collecting the existing geological exploration data in Dajiangping mining area of Yunfu pyrite,this paper mainly interprets and deduces the geophysical anomaly features near F1 fault and 723 overturned anticline structure.It is believed that the F1 Fault anomaly zone is an important site for searching for tectonically altered rock-type Pb-Zn deposits,and the anomalous section of the axial parts of the 723 overturned anticline are favorable sites for searching for Pb-Zn deposits in the interlayer fracture zones.
