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.
