| 中文摘要: |
| 在石哈河银多金属矿以西、以北曾开展过1∶20万区域调查、区域化探扫面工作,有金重砂异常显示,获得25个综合异常；但在矿区范围内未见异常,后经开展1∶5万矿调3幅联测工作,在石哈河矿区范围内发现Au、Ag、Pb等元素异常,从而选定该区开展进一步工作。通过1∶1万地质、高精磁、土壤化探等面积性工作,选择成矿有利地段安排激电中梯测量和综合剖面测量以及激电测深工作,实施部分地表工程揭露、深部钻探工程的系统控制验证,发现具有工业价值的银矿体6个,金矿体2个,铅锌矿体2个。石哈河银多金属矿是大青山—乌拉山地区的一个新发现,该矿的发现对寻找与火山热液有关的多金属矿床具有重要意义。 |
| 英文摘要: |
| The regional geological survey at scale of 1∶200 000 geochemical work and geochemical sampling (Map sheet:1) programme were counducted in the western and northern Shihahe silver polymetallic and more than 25 integrated anomalies were outlined with gold anomalies,but no anomalies in the deposit area. In later stage, the geolocial and exploration investigation at scale of 1∶50,0 (Map sheet:1) were followed, then geochemical anomlies of gold, silver, lead and other elements were outlined in the Shihahe deposit area, which were selected for further exploration. Based on the results of 10 000 geological mapping, high-precision magnetic survey and soil geochemical sampling, the geophysical IP survey and sounding electric survey were conducted in the favorable prospecting areas, then tested by surface trending and drilling. As a result, six silver orebodies, two gold bodies and two lead -zinc bodies were discovered in the Shihahe silver polymetallic deposit area. The new discovery of the Shihahe silver polymetallic deposit in the Daqing - Wulashan mountain region has significant implication for prospecting the volcanic hydrothermal type polymetallic deposits in the region. |
