Sedimentation Rate - an overview ScienceDirect Topics

Sedimentation Rate. Sedimentation rates are highest (>20m/Ma) during the early to late Oligocene section at Sites U1333 and 1334, and in the early and middle Miocene at Sites U1337 and U1338. From: Developments in Marine Geology, 2014. Download as PDF.

The Role of High Sedimentation Rates on the

The models show that deeply buried sediments are influenced by the long term average sedimentation rate, whereas the shallow deposits reflect recent depositional history. Whereas the latter may influence stability of local slopes, the former provides pore pressure gradients that

1998-9-1  The calculated sedimentation rates reflect the rate of subsidence of a rift-related basin and can be ascribed to tectonic and thermal subsidence. Comparison of the calculated sedimentation rates to published data from other Archaean and Proterozoic basins allows discussion of general Precambrian basin development.

Sedimentation rates range between 0.65 and 2.4 cm a 1 over a period of 10 to 40 years. The data provide additional information on the role of distance from the bank, overbank flow frequency, and channel geometry in controlling the sedimentation rate. Channel infills, lower than adjacent floodplains, exhibit higher sedimentation rates and convey overbank
