An exploration to Dawan Structure of Puguang gasfield illustrates that in complex mountains,the key problems of target processing to 3D seismic data include static correction,noise attenuation,consistency of both power and frequency,accurate acquisition of velocity along with wave-field complexity.

Lifting the mysterious veil of the tectonics of the Qinghai-Tibet Plateau by1∶250000 geological mapping;

The geomorphic feature of Yangtze river is controlled by the tectonic framework of the Qinghai Tibet block,Qinling Qilian Kunlun block and the Yangtze plate,and it is the result of the tectonic process of both Tethys tectonics and Pacific tectonics.

This paper analysed characters of geophysical fields, tectonics and geodynamics of eastern of Chinese continent and East China Sea region.

Dayao structure is a large-scale anticline trap in the central part of Chuxiong Basin.

Improvement and application of stereographic projection in tectonic

Based on the tectonic feature of Zhunger basin and its periphery, the paper discusses the formation of coal-accumulating basin, its coal-formation surroundings and coal-stage.

According to the tectonic unit characteristics of Upper Yangtze plate and the87Sr/86Sr,C13& 18 O analyses from the Silurian of North & South margins of Sichuan Basin,the following conclusions can be drawn:(1) During the Early Silurian,the North & South margins of the Sichuan Basin were located at the siliciclasticcarbonate ramp environments which were controlled by the inplate old land.

Middle Proterozoic geotectonics in the northeast margin of the Yangtze plate;

In the middle period of 20 century, during the development of Chinese geology, one academic prosperous situation had arisen in geotectonics.

The first one is the dynamics of the development and evolution of geotectonics.
