Abstract

On the basis of the field geologic, geomorphic, active tectonic observation and much more indoor research, we propose a dynamic model for the tectonic uplift and deformation of Gonghe basin and Longyang Gorge region. Modeling suggests that the ancient Gonghe lake was closed by the planation surface of 3000m height above sea level in the west part of Longyang gorge after the getting of deriving erosion of Yellow river to Guide basin, around the Gonghe basin, the fluid flowed to the lake ;The east part of Longyang Gorge in Lajim a and Luohantang a rea had been eroded to source,the fluid flowed to the Guide basin. When Gonghe movement took place,Gonghe basin,as a complete secondary rigidity active block,was extruded to east and rotated clockwise to southeast for little scale. Besides this,as its vertical uplifting displacement of west part was bigger than east the water barycenter of the ancient Gonghe lake deviated from west to east. So the water surface got across to 3000m planation surface,the water of ancient Gonghe lake flowed to Guide basin,then,Longyang Gorge had been formatted by the fast incision with the fluid between Gonghe basin and Guide basin.
- Gonghe basin,
- derive erosion,
- uplift scope,
- fluid incision,
- Longyang Gorge formation
