Dip-slip faults. Goal : To interpret dip-slip faults on seismic sections and to build on your interpretations to understand normal-fault and thrust-fault systems. Part-I : Normal-fault systems. Seismic-reflection profile of a large normal fault. Seismic-reflection profiles.

Seismic-reflection profile of a large normal fault
Growth strata: Sed rocks deposited during faulting. Thickest next to fault
The Tetons are a rotated fault block
Seismic-reflection profile of a thrust fault
Ramp: Dipping segment of the fault. Fault cuts up section
Flat: Subhorizontal segment of the fault. Fault follows beds.
Lateral ramp: parallel with transport direction
Oblique ramp: oblique to transport direction
Fold due to faulting
Moderately dipping limb
Steeply dipping overturned limb
Window: Hole eroded through hanging wall of a thrust fault that exposes footwall rocks
Klippe: Isolated remnant of thrust sheet. Typically topographic highs
