Quaternary Structure Feature in Forward Area of Tianjingshan Fault Zone and Its Contributing Factor Analysis

On the basis of the detailed geological survey, the structure features in forward area of Tianjingshan fault zone has been discussed in this paper, and it indicates that two thrust faults and fold strata belts in forward area of the south side movement of Tianjingshan fault zone, both are named the belts of Miaoshan and Hongjianshan fault and fold strata have being formed. The Hejiakouzi Quaternary anticline is introduced mainly which is a part of the Miaoshan fault and fold strata belt and pointing out that the anticline grew at mid segment near Hejiakouzi first in middle or late middle Pleistocene, then gradually developed to both ends in late Quaternary. The contributing factor of both belts of Miaoshan and Hongjianshan fault and fold strata and the kinematics relation between it and Tianjingshan fault zone are analysed by the traces of deformed strata.
