Abstract: In order to further study the Mesozoic tectonic characteristics and its restrictions on mineralization in northern Lüliang Mountain of Shanxi Province, using the digital mapping method, the authors conducted 1:250 000 regional geological survey in Pianguan County. Several large Mesozoic tectonic belts were found and their spatial distribution, properties, fault assemblage and kinematics characteristics were also investigated. It has been verified that Mesozoic period is the most important polymetallic metallogenic period and the mineralization was closely related to the Mesozoic magma with restriction by the NE concealed structures. Large flexure structures are the sign of strong uplift of the Earth’s crust. All the large tectonic belts in this area were formed by superimposing faults on the basis of flexure structures. This research can be of significant importance to the study of evolution and development of Mesozoic and Cenozoic structures.
