There are three sets of faults developed in Wugui Mountain area

the NE

theNNE and the NW.Effected by the plate collision during the Yanshan period andHimalayan period

natures of the faults have repeatly changed from compression—shear to tension—shear.All the faults have become normal faults during theneotectonic period.The fault-block uplifted area of Wugui Mountain bounded bythree sets of faults in different directions has uplifted intermittently during theneotectonic period

forming five erosion surfaces.The secondary fault-depressionwas formed in late Pleistocene or a little bit earlier.The secondary depressionwithin the Wugui Mountain fault-uplifted area is a thermo-anomalous belt.Re-search on how the three sets of faults cut off each other is of importance in loo-king for new thermal areas.
