The “dolomite problem”—how great
thicknesses of dolomitized platform carbonates form—has vexed geologists for
decades. In this paper, Humphrey and Quinn described the nature and
distribution of dolomite from three late Pleistocene raised reef terraces in
southeastern Barbados, West Indies. The data facilitated a conceptual model
that was then numerically tested by computer simulation. The results revealed the
how interaction of sea level fluctuations, sedimentation, rapid recurring
dolomitization, and subsidence controlled generation of dolomitic
successions.
