2010年,在对治多县尕龙格玛外围查涌地区1∶20万康刹勤乙类异常进行检查时,开展了1∶5万水系沉积物测量(测量范围为200 km2),圈出HS1、HS2和HS3综合异常,经查证均为矿致异常。在综合异常区又通过开展1∶1万土壤测量工作(测量范围为200 km2),共圈出综合异常18处,主要为Ag、Cu、Pb、Zn和Mo元素组合,具有套合好、异常值高及衬度大的特点,进一步对AP4、AP10和AP16土壤异常进行检查,发现铅锌矿体4条、铜矿体3条以及多处铜矿化线索。在HS2异常区的AP4、AP10、AP12和AP16土壤异常中,经槽探工程揭露发现3条铜矿体和4条铅锌矿体,显示出化探异常具有良好的找矿指示意义。根据工作程度推测,区内的成矿类型主要为与火山岩有关的块状硫化物型矿床、与印支期花岗闪长岩侵入有关的矽卡岩型矿床及与构造活动有关的热液型矿床。
2010年,在對治多縣尕龍格瑪外圍查湧地區1∶20萬康剎勤乙類異常進行檢查時,開展瞭1∶5萬水繫沉積物測量(測量範圍為200 km2),圈齣HS1、HS2和HS3綜閤異常,經查證均為礦緻異常。在綜閤異常區又通過開展1∶1萬土壤測量工作(測量範圍為200 km2),共圈齣綜閤異常18處,主要為Ag、Cu、Pb、Zn和Mo元素組閤,具有套閤好、異常值高及襯度大的特點,進一步對AP4、AP10和AP16土壤異常進行檢查,髮現鉛鋅礦體4條、銅礦體3條以及多處銅礦化線索。在HS2異常區的AP4、AP10、AP12和AP16土壤異常中,經槽探工程揭露髮現3條銅礦體和4條鉛鋅礦體,顯示齣化探異常具有良好的找礦指示意義。根據工作程度推測,區內的成礦類型主要為與火山巖有關的塊狀硫化物型礦床、與印支期花崗閃長巖侵入有關的矽卡巖型礦床及與構造活動有關的熱液型礦床。

In 2010,examining the 1∶20 million brake Qin B anomaly in Zhiduo County,Galonggema peripheral check Chung area,carried out the 1∶5 000 stream sediment survey 200 km2 and delineated the HS1,HS2 and HS33 composite anomalies,which were mineralization anomalies after verification.In the composite anomaly area, 1∶10 000 soil investigation have been carried out and 18 composite anomalies were found.The result shows that the anomalies mainly are the element combination of Ag,Cu,Pb,Zn and Mo.And it has the characteristics of good identity,high value,and sharp contrast etc.In HS2,further to the AP4,AP10 and AP16 soil anomaly inspection, found that 4 Pb-Zn orebodies,3 copper orebodies and several clues to copper mineralization.The results show that the geochemical anomaly has good prospecting indication significance.According to the work degree,speculate that the mineralization types mainly are the massive sulfide deposit,the skarn type deposit and the hydrothermal type deposit.
