| 研究区位于内蒙古自治区呼伦贝尔市鄂伦春自治旗甘河镇，处于大兴安岭北段根河火山盆地 Pb-Zn-Ag多金属成矿区，成矿条件优越。针对该区特殊的森林沼泽和植被覆盖景观，与通常的水系沉积测量在样品采集和加工存在很大的差别，本研究开展了该区 1∶50000水系沉积物测量，圈定了 15个综合异常区，异常组合以铅锌银(钼)为主。其中规模较大的 HS03和 HS10甲类综合异常产于奇力滨火山洼地中，受火山岩及后期酸性岩浆侵入活动影响。通过初步的异常查证和槽探揭露，结合甘东七运铅锌银矿床、兴滨南铅锌钼等矿点，在 HS03成矿预测区，圈定了甘东七运铅锌银钼找矿靶区(A1)，在 HS10成矿预测区，圈定出兴滨南铅锌银钼找矿靶区(A2)、兴滨东铅锌银找矿靶区(B1)，为该区进一步开展地质找矿提供参考。 |
| 英文摘要: |
| The work area is located in Ganhe Town, Oroqen Autonomous Banner, Hulunbuir City, Inner Mon.golia Autonomous Region, and is located in the Pb-Zn-Ag polymetallic mineralization area of the Genhe Volcanic Basin in the northern section of the Daxing'an Mountains, with superior mineralization conditions. For the specialforest swamp and vegetated landscape in this area, there is a great difference in sample collection and processingfrom the usual drainage sediment survey, a 1∶50000 scale sediment survey was conducted to delineate 15 compre.hensive anomaly areas, with the anomaly combination mainly consisting of lead, zinc, silver (molybdenum). Thelarge-scale HS03 and HS10 Class A comprehensive anomalies occur in the Qilibin volcanic depression, influencedby volcanic rocks and later acidic magma intrusion activities. Through preliminary anomaly investigation and trench.ing, combined with ore occurrences such as the GandongQiyun lead zinc silver deposit and Xingbinnan lead zincmolybdenum deposit, the prospecting target area (A1) of the GandongQiyun lead zinc silver molybdenum depositwas delineated in the HS03 mineralization prediction area, and the Xingbinnan lead-zinc silver molybdenum pros.pecting target area (A2) and Xingbindong lead zinc silver prospecting target area (B1) were delineated in the HS10mineralization prediction area, which has certain reference value for further geological exploration in this area. |
