江西铜鼓溜竹洞矿区化探异常特征及找矿方向

Geochemical anomaly characteristics and prospecting direction in liuzhudong mining area,Tonggu,Jiangxi Province

溜竹洞矿区处于九岭隆起的西侧,成矿地质条件优越.通过土壤地球化学测量,总结分析了元素异常形态及富集规律,厘定了Au矿化活动和成矿规律,进一步明确了找矿方向.研究表明:区内土壤地球化学异常元素以Ag、AS、Sb、Ag为主,元素异常多呈带状、片状重叠产出;圈定了3处Au-As组合异常带,韧性剪切带与Au、As组合异常叠加部位是寻找金多金属矿的有利部位.

Liuzhudong mining area is located in the west side of Jiuling uplift,with superior metallogenic geological conditions.Based on the soil geochemical survey,the abnormal forms and enrichment rules of elements are summarized and analyzed,the Au mineralization activities and mineralization rules are determined,and the prospecting direction is further defined.The results show that the main elements of soil geochemical anomalies in the area are AG,as,Sb and Ag,and the element anomalies are mostly zonal and sheet-like.Three Au as assemblage anomalies are delineated,and the superposed part of ductile shear zone and Au as assemblage anomalies is the favorable part to look for gold polymetallic ore.
