摘要
绿梁山地区位于柴北缘造山带上,其内分布荒漠、戈壁等地貌,且遭受风积物等因素的影响,致使诸多地质异常信息被削弱或掩盖,对地质找矿工作造成了严重干扰。针对绿梁山地区独特的地貌特征及成矿背景,采用基于成矿元素复杂度的地球化学数据处理方法对1∶5万水系沉积物测量结果进行分析,快速优选出了重要找矿靶区,经验证新发现了鱼卡铜金矿床,为下一步找矿工作提供参考。
The Lüliangshan area is located on the Qaidam Northern Margin Orogenic Belt.In the area distributes desert and gobi landscape, and influenced by factors such as aeolian deposit, a lot of geological anomalous information is blurred or buried, imposing serious interference on geological prospecting work.Based on the unique landscape and metallogenic settings in the Lüliangshan area, a geochemical data processing method based on ore-forming element complexity is used to analyze the 1 ∶50 000 stream sediment survey results and rapidly selects important prospecting target areas.After verification, Yuqia Copper-Gold Deposit is discovered, providing references for further prospecting.
