滇西普朗矿区南部及外围化探异常特征及找矿方向

普朗铜矿区是三江成矿带的超大型矿床，成矿地质条件优越，但受限于复杂的地理环境，矿区南部及外围地质研究程度较低。通过地球化学测量，总结分析了元素异常形态及富集规律，厘定了多金属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、W、Zn、Au为主，元素异常多呈带状、片状重叠产出；圈定了Au As Ag W（HS1）、Au W Cu As Mo Ag（HS2）、Zn Hg As W Sb（HS3）及Au As Zn Hg W Sb（HS4）4个综合异常带，其中，HS2、HS3属矿致异常；HS2异常带与岩浆岩、沉积岩接触带吻合度高，具有优越的控矿、容矿地质条件，钻孔揭露的金矿层是寻找金多金属矿（化）体的有利部位。

Geochemical Anomaly Characteristics and Prospecting Direction of Southern and Periphery of Pulang Mining Area,Western Yunnan Province

Pulang Copper Mining Area is a super large deposit in Three River metallogenic belt,which characterized by superior ore forming geological conditions.However,the southern and periphery of Pulang mining area has the low research level,by limited to complicated geographical environment.Through the geochemical survey,the anomaly shape and enrichment regularity of element are analyzed.Besides,the polymetallic mineralization and mineralization regularity are redefined,and further defined the prospecting direction.The research results show that the anomaly elements of soil geochemistry mainly includes Ag,W,Zn and Au,which overlap occurred by zonal distribution and flake distribution;four comprehensive anomalies,which including Au As Ag W (HS1),Au W Cu As Mo Ag (HS2),Zn Hg As W Sb (HS3) and Au As Zn Hg W Sb (HS4) are delineated;the HS2 anomaly belt is highly consistent with magmatic rock and sedimentary rock contact zone,which characterized by superior ore controlling condition and ore containing condition,the gold ore bed which exposed by borehole engineering can be regarded as the favorable position to find gold polymetallic mineralization/ore-bodies.
