Abstract The active faults impact of Gangga Graben Basin on the railway site selection cannot be ignored in the geological work in the early stage of China-Nepal Railway. Soil radon measurement work was carried out to identify the location and activity of boundary faults of Gangga graben basin and three horsts, and other hidden faults. The approximate positions of the three boundary faults in the east, west, and north of the basin were ascertained and the positions and extension directions of the faults on both sides of the three horsts were verified through measurement. The faults activity within the basin was analyzed, with the overall activity of the northern faults and eastern faults being stronger than that of the southern faults and western faults. This research could provide scientific basis for the site selection work of China-Nepal Railway.

Key words： graben basin radon gas measurement fault activity
