Rift basin vs foreland basin sedimentation?

    How does sedimentation compare between rift basins and foreland basins?

    Does each have differing rates of sedimentation?

    What about the convexities/concavities in the sedimentation profile?

    Also - why are rift basins often filled up with lakes while foreland basins sometimes aren't?

  3. Doesn't the source material for sedimentation also play an important part?
     
  4. I don't have specific data, but surely this would depend upon relative rates of uplift of source areas, coupled with the size of the basin. I would expect a broad overlapping of the ranges.

    I suspect that foreland basin would generate overall higher averages, since it exists because of compressional forces, and the rifts because of tensional.
