Abstract

In the Bahamas the post-Wisconsin rise in sea level flooded an irregular limestone surface which superimposed local increases and decreases in current velocity on the regional tidal regimen. The calcium carbonate supersaturated bank waters of the shoaler unsheltered rock areas were characterized by considerable current agitation and consequent oolite formation. The rate of oolite accumulation kept pace with or exceeded the rate of sea level rise, thereby resulting in the formation of extensive oolite shoals. The distribution of these shoals reflects the distribution of the limestone prominences which underlie them. The form variation exhibited by the shoals is apparently a product of the continuous or discontinuous nature of the underlying rock ridges.
