| 中文摘要: |
| 通过研究区域地球化学特征及预查区地质特征,发现区内Au、Ag标准离差及变化系数较大,说明Au、Ag元素在区内分布不均匀,易富集而成矿,区内发现有那更康切尔、永巴埂、克得休玛等银多金属矿。通过预查工作,运用地化综合手段,发现了新的工业银矿体11条,其中Ⅲ-3矿体平均品位41.4~1371.63 g/t,最高2320 g/t；对HS6南部与北部异常、地质特征、控矿因素及找矿标志的综合分析对比,矿(化)体的赋存部位及矿石类型与那更康切尔银矿一致,说明该区具有较好的银矿找矿潜力。 |
| 英文摘要: |
| In recent years, some progress has been made in the exploration of independent silver deposits.In order to better analyze the prospect of silver polymetallic deposits in the north of Nagengkangqieer, the paper studies the regional geochemical characteristics and geological characteristics of the pre check area.The standard deviation and variation coefficient of Au and Ag in the area are large, which shows that Au and Ag elements are distributed inhomogeneously in the area, easily enriched and mineralized.Silver polymetallic deposits have been found in the area,such as Nagengkangqieer, Yongbageng, Kedexiuma and other silver polymetallic mines.Based on the implementation and comprehensive research of the project “pre inspection of the North Silver Polymetallic Ore in Nagengkangqieer, Dulan County, Qinghai Province”, through the pre inspection work and the use of comprehensive geochemical means, a new industrial silver ore body has been found; through the comprehensive analysis and comparison of the anomalies, geological characteristics, ore control factors and ore prospecting criteria in the South and north of HS6.Host site and ore type of the mineralized body are consistent with that of Nagengkangqieer silver mine,indicating that this area has a good potential for silver exploration. |
