SEDIMENTATION RATES

Sedimentation rates in the subjacent black shale facies are 8.5 m/m.y., a rate at the high end of those found in this interval during Leg 207. The only datum below the black shale interval yields a maximum age of late Albian (see "Biostratigraphy" ), which is consistent with

Sedimentation Rate an overview ScienceDirect Topics

Sedimentation velocity analytical ultracentrifugation is a fundamental hydrodynamic method that measures the rate of sedimentation of macromolecular species under the influence of a high centrifugal field. It has the advantage of being a measurement made in free solution (no matrices or surface effects) under native and biochemically relevant
