A regional perspective of shallow-burial diagenesis of deep-water periplatform carbonates from the northern Bahamas

Abstract

Stage 1 diagenesis (0-10 meters below the seafloor, mbsf) results in rapid, extensive calcitization and local dolomitization in marine-derived pore fluids. Below 10 to at least 185 mbsf, stage 2 diagenesis continues to alter primary components, leading to ooze-chalk and chalk-limestone transformations and low amounts of dolomite, while rates and amplitudes of change are considerably less than in stage 1. -Authors
