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。该景观区1∶5万水系沉积物测量发现"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。
The Shuangkoushan gobi desert region is located in an important 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.
