摘　　要：目前探矿工作对物探的测深要求越来越高,而可控源同时具有剖面法和测深法的特点,是一种比较理想的矿产勘查手段。在西藏隆子县某铅锌多金属矿进行深部勘查中,通过研究已知相邻矿区与本矿区的构造和矿体的电性响应特征和规律,并结合已知地质资料,建立了本矿区的地质—地球物理电性模型。应用此模型和已有地质资料对后面的13条剖面反演与解释工作进行指导,收到很好的效果,为矿区深部和外围进一步寻找隐伏铅锌矿体提供了可靠的依据。At present,the demand for the geophysical prospecting sounding is higher and higher in the exploitation work.The CSAMT has the features with both of the cross-section and sounding methods,which is good for mining exploration.In lead-zinc polymetallic exploration of Longzi,Tibet and through the studies on the electric response characters and regularity of the structure and ore body between the known deposits nearby and the deposit and combined with the known geological data,the geological～geophysical electrical model is set up,and the model and the known data are applied to making a guidance for the inversion and interpretation of the next 13 sections,which achieves a good result and provides a reliable basis for the further exploitations of the concealed lead-zinc deposits.
