结合区域成矿地质背景，以云南勐腊县南坡铜矿床地质勘查成果为依据，通过深入分析矿区成矿地质条件、成矿物质来源、成矿规律及矿床成因，总结了矿床的控矿因素，并对矿区物化探异常进行了解译，结果表明：①南坡铜矿床严格受构造、地层层位、古沉积环境和岩性的控制，其中次生富集铜矿体则与构造关系密切；②矿床成矿物质来源主要为围岩地层，最具代表性的为含矿标志层(“紫色层”)；③矿区内硫化铜矿石视极化率平均值为4．9%，其高极化、中阻的显著特征显示硫化物的存在；④I#1、I#2、I#6异常呈串珠状分布，构成与构造方向( NEE向)基本一致的串珠异常，与已知的矿化线索基本吻合；⑤Ag、Cu、As等元素异常较强，其中HSI#、HSII#异常中心与I#1物探异常及NW向断裂较吻合。综合上述找矿信息，对矿区找矿远景进行了讨论，圈定了矿区中部、东南部为有利找矿靶区，为矿区后续找矿工作提供参考。

Combing with the regional geological background and the geological exploration results of the Nanpo copper deposit in Mengla county,Yunnan province,the ore-forming geological conditions,source of ore-forming materials,regularity of mineralization( relationship of source bed and ore-forming,relationship of stratigraphic position and ore-forming,relationship of formation lithology and ore-forming,relationship of tectonic and ore-forming,relationship of interaction zone with light purple and ore-forming) and genesis of mineral deposit in the mining area are analyzed in depth,the ore-forming factors of the Nanpo copper deposit are summarized, the geophysical-geochemical anomalies of the mining area are interpreted. The results show that:①the Nanpo copper deposit is mainly controlled by the tectonic,stratigraphic position,palaeosedimentary environment and lithologic,the secondary enrichment copper ore-body of the Nanpo copper deposit is closely associated with tectonic;②the ad-jacent rock stratum is the main ore-forming materials source,the ore-bearing strata("purple formation") is the most representa-tive adjacent rock stratum;③the average apparent polarizability value of the copper sulfide ores in the mining area is 4. 9%, the presence of sulphide is displayed by the significance characteristics of high polarization and medium resistance of the cop-per sulfide ores in the mining area;④the I#1、I#2、I#6 anomalies are distributed with the scattered points and beaded form,they are constructed the beaded form anomalies that is basically identical to the tectonic direction( NEE) in mining area,the anomalies characteristics are consistent with the mineralization clues that are already found in mining area;⑤the anomaly intensity of Ag, Cu and As are higher than other elements,the the HSI#、HSII# anomaly centers are fit well with the I#1 geophysical anomaly and the NW-trending fracture. Based on the prospecting information that is discussed in this paper,the prospecting prospective of the mining area is discussed in detail,therefore,the central and southeast part of the mining area are delineated as the favorable prospecting target areas to provide reference for the further prospecting work in the mining area.
