| 摘 要： | 在四川省石亭江地区隐伏断裂构造的地面解译过程中，当地特殊的河床、河滩地貌限制了常规物化探方法的应用。而通过积累式地气测量成功获取了当地隐伏断裂的位置和宽度信息。不仅验证了遥感解译对隐伏断裂预测的可靠性，还给出了更精确的定位信息，为当地地热资源勘查提供了重要帮助。在河床、河滩地区，积累式地气采样克服了常规物化探方法的局限性，表现出较好的环境适应性和实用性。

| Abstract: | In the process of prospecting for concealed faults in the Shitingjiang area by means of the remote-sensing geological interpretation,local special riverbed and river shoal landform has hindered the researchers from the application of some common geophysical-geochemical methods.In this paper,the geogas prospecting method was employed to obtain the location and breadth information of local concealed faults.It is shown that geogas prospecting can not only verify the reliability of remote-sensing interpretation but also offer more accurate location information,thus providing important help for the exploration of local geothermal resources.In river bed and river shoal areas,the influence of the surface environment on the accumulative geogas prospecting is insignificant,which is different from things of other common geophysical geochemical methods.The accumulative geogas prospecting has fairly good environmental adaptability and practicability. |
