摘　　要：根据广西某锡矿的矿床地质特征及地球物理特征,建立了矿区的地质-地球物理模型。结合地质-地球物理模型及CSAMT法测量结果,推断了隐伏岩体顶界面及矿化富集规律。钻孔验证结果与物探推断结果基本一致,证实了CSAMT法在本矿区深边部找矿的有效性,所建地质-地球物理模型对本矿区成矿预测具有一定指导意义。Based on the mineral deposit geologic and geophysical character of a tin ore deposit in Guangxi, we built the geologic-geophysical electrical model, predicting the tin ore-body probably occurring within the top of the raised granite and both sides of the contact structure. Combining the model and the inversion results of the testing profile with CSAMT method, we inferred the top interface of the concealed rock-bodies and min- eralization enrichment regularities. Drilling verification is in line with our geophysical exploration inference results, confirming that the CSAMT method is effective for predicting the deep rock-bodies, the model can guide the prediction of the concealed ore-bodies.
