摘　　要：海南岛陵水县南平农场银金矿的发现为海南岛九所-陵水深大断裂带东段找矿提供了重要线索。有望提供一批可供进一步勘查开发的后备资源基地,从而拉动该区多金属矿的商业性勘查开发。本文在分析成矿地质条件基础上,对矿区的物化探特征、异常进行分析查证,评价找矿前景。研究表明:矿区中高温热液元素组合为特征的土壤化探异常明显,化探异常和激电中梯低(中)阻高极化异常带位置吻合较好,异常与深部矿化体有密切关系,成矿作用和早白垩世燕山期岩浆岩相关,成因类型为热液蚀变岩型。The discovery of the silver-gold deposit in Nanping farm,Lingshui county,Hainan island provides important clues for prospecting in the east section of the Jiusuo-Lingshui deep fault zone in Hainan island.It is expected to provide a batch of reserve resource bases for further exploration and development,so as to stimulate the commercial exploration and development of polymetallic mines in this area.Based on the analysis of the mineralization geological conditions,this paper analyzes and verifies the geophysical and geochemical characteristics and anomalies of the mining area,and evaluates the prospecting prospects.Studies show that the geochemical anomaly of the soil characterized by the combination of high-temperature hydrothermal elements in the mining area is obvious,and the geochemical anomaly is in good agreement with the location of the IP anomaly zone with low(middle)resistance and high polarization,and the anomaly is closely related to the deep mineralization.Relationship,mineralization is related to early cretaceous Yanshanian magmatic rocks,and the genetic type is hydrothermal altered rock type.
