The Symposium on Tancheng-Lujiang fault zone held at Weifang, Shandong province on November 1-10, 1980 was organized by the Geological Society of China, accompanied with field trip. The problems of the regional geological investigations, exploratory survey for ores, geophysical prospecting, seismogeology and images interpretation have been thoroughly discussed.All representatives came to following common understanding: (1)Tancheng-Lujiang fault zone is a gigantic fault zone in East Chinese continent, related to the formation of ores and earthquakes; ( 2 ) this fault zone has been subjected to a complex process in formation and evolution with a great variety of motive mode at different stages and periods and characterized by the complicated geomechanical nature of compressive shear and tension, on the one hand, and of left-lateral and right-lateral displacement, on the other hand; (3) it is fault zone that is still active at present. However, a few of important questions remain:
