Neotectonics of Eastern Tibet and Its Control on the Wenchuan Earthquake;

During the past more than ten years, the research front on neotectonics concentrated on the field observations and theoretical models of the interaction between surface and crustal processes.

Based on some new data from the Exploration Institute of CNOOC Research Center and the early studies,the neotectonics and its activities of the fault zone were studied,the results showed that the reactivity of the Paleogene System faults(old faults) in Yingkou-Weifang fault zone had generated minor faults and folds in the overlying Guantao Formation,Minghuazhen Formation and Qutanary System.

Impact of neotectonic movement on shallow layer geotemperature in mid-north of Jinzhong basin;

geological basis, neotectonic movement and neoid climate fluctuation are discussed.

According to the orientations,the younger structures can be classified into two basic kinds: inherited and neogenic structures.

The paper discussed,in succession of tectonic cycles,the neogenic structures in each part,including the ages,orientations and active modes.

The roles of controlling basin development of the fractures with varied strikes,including the W-E and NE-striking fractures in the basement,were analysed,which emphasized that the neogenic structures of N-S orientation appearing in Mesoproterozoic and NW-striking forming in Early Ordovician played an important part in the fault-block\'s evolution and oil-gas accumulation.
