About the cover:
Spectacular fold-thrust structure imaged by CGGVeritas from the deepwater Niger Delta—but is the deformation simply a matter of thrusting in unconsolidated sediments like this? Field of view ~5 km by 5 km × 3 seconds from a 3-D seismic cube image courtesy of the Virtual Seismic Atlas ( See “Evaluating lateral compaction in deepwater fold and thrust belts: How much are we missing from “nature‚Äôs sandbox”?,” by R.W.H. Butler and D.A. Paton, p. 4–10.
