A RECOVER FOR TRAJECTORY OF MAIN FAULT OF 639 PROFILE IN JIYANG DEPRESSION
济阳坳陷639剖面主干断层轨迹的恢复

It's a significant meaning to looking for anticline trap of roller anticline through confirming geometry of normal listric a fault,poor seismic data in deeper section usually bothers researchers during their exploring process.A inclined shear technique by rotating tangent of antithetic subsidiary fault could result in more accurate extension,thus tracing fault trajectories.We have had a great achievement in tracing trajectories of listric of 639 profile in Jiyang sag.
