本文亮点

滩北雪峰位于祁漫塔格地区西段，是利用化探手段新发现的构造蚀变岩型金矿，探讨该金矿的化探异常特征及其找矿前景，对在祁漫塔格地区寻找金矿具有重要指导意义。在滩北雪峰地区开展了1/1万土壤地球化学测量，结果显示Au为富集元素，变异系数较大，R型聚类分析显示Au与Bi呈显著正相关，表明该区金成矿可能与中低温热液活动有关。进一步分析元素地球化学特征，并结合矿区地质背景，圈定出13个土壤综合异常，选择AP7、AP9异常区开展了异常查证工作，发现1条金矿化蚀变带，带内圈定出3条金矿体，地表亦发现多处金矿化线索。结合成矿地质条件，初步建立了地质、地球化学和构造等方面的找矿标志，探讨了矿床成因，指出今后找矿方向。土壤地球化学研究表明:该区具有良好的找矿前景，是寻找构造蚀变岩型金矿的有利地区。

Highlights

Qimantage metallogenic belt is located in the western part of the East Kunlun Mountains.It is an important metallogenic belt in the western part of China.Superior metallogenic geological conditions have resulted in abundant mineral resources in this region.In recent years，a large number of mineral deposits related to intermediate-acid magmatic activities have been discovered in the Qimantage metallogenic belt.The genetic types of the deposits are mainly skarn，porphyry，high temperature hydrothermal，sedimentary metamorphic，sedimentary，hot water sedimentary-reformed and volcanic rock type.The minerals include copper，iron，lead，zinc and other metals.Tanbeixuefeng is a newly discovered tectonic altered type gold deposit in the region, which is located in the Qimantage back-arc rift basin，and the metallogenic geological conditions are very favorable.In this study，through 1∶10 000 soil geochemical survey in Tanbeixuefeng area，the results shows that Au is an important enriched element with a large coefficient of variation，indicating that there is superimposition of late stage mineralization.Moreover,R-type cluster analysis shows that Au and Bi are significantly positively correlated，indicating that Au mineralization may be related to mesothermal and low-temperature hydrothermal activities.Further analysis of geochemical characteristics of elements，combined with geological background，13 comprehensive soil anomalies dominated by gold have been delineated， trench prospecting has been carried out in AP7 and AP9 anomalous areas.A gold mineralization alteration zone has also been found，and three gold orebodies have been delineated in the zone.The gold orebodies are developed in the NW-trending structural fracture zone，as well as joint structure.The ore-hosting lithology is silicified altered rock and strong limonization.Several gold mineralization clues have been found on the surface，such as silicification，sericitization，and pyritization.Furthermore,based on the analysis of metallogenic geological conditions，the prospecting criteria of geology，geochemistry and structure are preliminarily established.Moreover，the genesis of the deposit is discussed and analyzed.Therefore，this study point out the prospecting direction in the Tanbeixuefeng area as follows：（1） The Au is already found in the No.1 mineralized alteration zone，thus the drilling should be carried out；（2） Compared the No.1 mineralized alteration zone，the prospecting should be focussed on the NWW fault；（3） Other unidentified Au high-value points in soil anomalies；（4） Other unchecked Au high-value points in soil anomalies，and Au and As combination anomalies should be strengthen prospecting work.It is a favorable area of prospecting for structural altered type gold deposits.Surface tracing and deep verification work in this area are expected to make breakthrough prospecting progress.
