Three hot sources in prospecting area of Liaoda geothermal well is a hot source in the depths of the earth s crust, a hot source from Liaokao fracture rising and a hot source to produce by Liaokao fracture s move.

According to geochemical anomalies in combination with characteristics of geophysics,geology,mineral resources and products revealed during the eco-geological investigation along the Yangtze River Economic Belt of Chongqing,the authors hold that their exists a nearly NS-trending concealed fault belt in Wanzhou and an EW-trending concealed fault belt in Fuling.

This paper has described in brief hydrogeological and geothermal conditions of Longmen State Grain Depot in Luoyang City, analyzed and interpreted integrated geophysical data obtained from the exploration locating of hot water and cool water wells over the same concealed fault in this area and, on such a basis, determined sites and depths of the drill wells.

Several of them,including As,Au,Fe,La,Sm,exhibit a regular abnormal distribution,which reflects the concrete position of the concealed fault in this area.

The application of gas radon measuring in the research of buried faults in Shengli oil field;

Through the analysis and comparison of the correlative datas of gamma-ray spectrometry,and Rn survey,this paper explains and proves the existence of the two NWW trending buried faults named Dayi-Zhuwapu-Wuzhutuo and Shuagliu-Chengdu-Deyang.

Shallow crustal velocity structure and hidden faults of Kunming city region;

Exploration on the hidden faults in Shenyang City, Liaoning Province;

The good significance of this method for explorating the hidden fault zone and deep uranium deposits in northern Sichuan is confirmed also.
