| 中文摘要: |
| 双口山荒漠、戈壁景观区位于我国柴北缘重要成矿带上。景观区1:5万水系沉积物测量“HS-9-4”综合异常弱小、零散、峰值低；元素空间套合性差，无规律性；多元素仅有1级异常分带。根据其本身自然地理景观，经“衬度异常法”与常规方法对比，发现“HS-9-4”弱小异常值得重视，对该异常开展了查证工作，最终在异常区发现了多处与金相关的矿（化）体及线索，为下一步地质工作提供了可靠依据。 |
| 英文摘要: |
| The Shuangkoushan gobi desert region is located a metallogenic belt in the northern margin of Qaidam. The 1:50000 stream sediment survey reveals weak “HS-9-4” geochemical anomalies, which are scattered and of low amplitude, poor matching of elements and irregular spatial distribution. There is only one element having first-order geochemical anomaly zoning among many elements. According to its natural geographical landscape, through comparison between the contrast anomaly method and conventional anomaly method, we suggested that this “HS-9-4” weak geochemical anomaly is worth studying. By investigation and test to this anomaly, we finally discovered some ore bodies and clues related to gold, which provide a reliable basis for further geological work. |
