摘　　要：依据"小岩体成大矿"和"岩浆通道理论",对杨柳坪铜镍硫化物矿床的岩浆通道进行研究,在充分梳理前人地质勘查成果的基础上,运用w(Pd)/w(Ir)、w(Ni)/w(Cu)在各矿体品位的变化规律判断含矿岩浆通道的运移方向,随后通过开展地质、地面高精度磁测和AMT法对深部地质特征进行研究,推断出深部岩浆通道的位置,提出了在杨柳坪矿区深部找矿工作的综合方法。According to the theory of ’large-scale mineralization occurring in small intrusion’ and ’magma conduitsystem’, the authors investigated the magma conduit of the Yangliuping magmatic Cu-Ni sulfide deposit.On the basis of the study of all geological documents, the values of w(Pd)/w(Ir)、w(Ni)/w(Cu) were used to estimate the moving direction of magma conduit. Then geological profiles, high precision geomagnetic survey and the AMT measure were deployed in search for the magma conduit. The integrated measures in search for deeply-buried orebodies at Yangliuping was summarized.
