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。

Abstract:

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.
