This volume will be of special interest to carbonate
sedimentologists, geochemists, petroleum geologists, engineers, and
seismologists. It addresses fundamental aspects of prograding
carbonate platforms in a Neogene example from Great Bahama Bank. A
remarkable seismic profile, which imaged the prograding margin,
provided the seismic stratigraphic framework. Two continuously-cored
and logged borings on the profile produced the ground truth for
testing and characterizing processes: lithologies and ages of
sequence boundaries; influence of sea level fluctuations on
progradation, controls on impedance contrasts in carbonates; fluid
flow through the submerged margin; log responses of different
lithologies; and the origin, ages and depositional environments of
the platform top and prograding clinothems. The new findings on
diagenesis are of special interest, including complete mineral
stabilization in seawater, early burial dolomitization related to
sequence boundaries and how diagenesis controls sonic velocity and
permeability.
