In the paper the authors give out the major outcome obtained by using magnetotelluric sounding in the Dongting depression in Hunan Province, and carefully analyse and deduce the regional structural framework, electrical property structure of the depths and the distribution character of high conductivity layers in the earth's crust and the earth's mantle of the Dongting depression in Hunan.

The Study on Tectonic Evolution History of Western Depression Belt in Bayanhot Basin;

Gas exploration has achieved a great success in the western depression of Sichuan Basin, but difficulty of exploration and development also has been increasing.

The deposita of shallow marine-littoral, lacustrine and fluvial facies of Upper Triassic in west Sichuan depression occur with abundant oil-gas resources, which form a petroleum system dominated by natural gas.
