Nice idea - but doing something explicitly economically-relevant in the seismic playlist isn't part of my development plan - sorry. Too much else to do first...
Great, different layers reveals their time order and also a contractional regime in the surface of the passive continental crust. Below the decollement and the left fold-thrust system, can the white zone be taken as transition zone in structural dynamic regime, or a zone with strike slipping? And still below that, the red boundary line is bended down, showing that's in the extensional regime.
The contractional structures in DW Nigeria are driven by gravitational collapse of the thick sediment piles deposited on the continental margin - entirely unrelated to the processes of rifting that formed the margin in the first place. Check out the video on submarine thrust systems for more on this!
Well, with subsurface geological interpretation you NEVER know the right answer ... and there generally is more than one way to interpret an image... especially where the structure seems complex (as in the LH anticline)... in some respects we're always wrong (to some degree)...
Rob you are really doing a good Job. I wanted to request a video on interpreting trapping mechanisms on seismic profiles

Rob, thanks once again for such a good video. Please keep them coming!
Thanks!
Thanks Rob, it s very useful and your enlightening
Thank you so much this video is so clear! This has been really useful for my Uni studies
thanks... glad it was useful for you

Thank you so much. Then, both continental and oceanic crust along the Atlantic passive boundary can have this thrust systems.@@robbutler2095
These types of systems are restricted to the sedimentary cover and don't impact on the crustal structure...@@user-ij3qo6xl9s
Thanks a lot for your reply. That's great! @@robbutler2095
very nice, I really enjoyed that, thank you. Is -non-unique' a fancy way of saying 'could well be wrong'?
