Prereef deposits consist of coarse-grained dolostone composed of visible dolomite crystals, fossil shell debris, and fewer whole shells. This rock represents an original sediment of carbonate sand. The rock shows extensive cross-bedding, a feature that indicates a shallow seafloor on which sediment particles were moved frequently by waves and currents.
