Description :
The AA. survey Holocene paleosols profiles on the Paleo-alluvial-pluvial fans in the 3 middle segments in front of the mountain, and carry out dating age. Then they compare paleosols ages on the Paleo-alluvial-pluvial fans to the paleoseismic events along the Daqingshan piedmont fault discovered by trench techniques. The contrast result demonstrates that paleosols ages on the Paleo-alluvial-pluvial fans have very close correspondence relations with paleoseismic events along the Daqingshan piedmont fault. So they think that paleosols ages on the Paleo-alluvial-pluvial fans can be used to reveal fault activity history. They have built the model of time relationship between paleosols ages on the Paleo-alluvial-pluvial fans and fault activity history by further step.
