A Look Back…25 Years: Mixed Dolomite

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.
