Dirk ..the info u need is hereOn sediments at different parts of a basin ..but please remember this basin had some inversion going on after the Campanian was already in place so it may very well be that the sediments in the proximal fans at 5000 meters are homogeneous to or close in size to the basin fan sediments ..the AVO responses do a pretty good job in derisking that aspect these days ..of course someone will say .."speculation" lol ..anyways why y'all so fearful ? Balls up lol
