Subsurface Geology Prograding Carbonate Platform Margin Great Bahama Bank: Results of the Bahamas Drilling Project

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 continuouslycored 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.
