Abstract
The role of terrigenous (and non-framework carbonate) sedimentation has not been prominent in models of coral reef growth and evolution. We derive and discuss a semi-quantitative model which relates coral reef growth to sedim entation. The model is independent of coral biology and is based upon the r elative net rates of framework and non-framework sediment accumulation and/ or removal. The model might enable some forecasting of long-term responses to changes in sedimentation regime and other environmental factors. The occ urrence of turbid-zone reefs is successfully explained in regions of very h igh turbidity but with little or no net sediment accumulation. Potential fu ture use of the model may include aiding prediction of the effects of other geological and oceanographic factors on the growth or demise of coralline communities.
