英文摘要	Crustal velocity structure and structural information can be inversed precisely by seismic tomography. The shallow crustal (1200 m above) velocity can be achieved by first arrival time tomography in a basin. Prospecting information is always closely linked with the geochemical anomalies. Many significant metal element anomalies have been found by geochemical analysis of the sediment samples from shot holes. Correlation analysis between velocity imaging of five lines and mapping rock properties, compared with geochemical anomaly, has finished. The results show that sedimentary rocks, volcanic rocks and intrusive rocks have different velocity ranges in the Luzong basin. Fine velocity analysis shows that shallow crustal structure varies, and has good correspondence to known geology, rock, structure and distribution of ore deposits in the district. Velocity imaging can accurately reveal the spatial distribution of buried intrusive rocks. Combining with geochemical analysis, information of gravity and magnetic anomalies, location of concealed deposits and targets at depth can be predicted for exploation.
