A. Model for cover subsidence sinkhole development. Undisturbed, impermeable bedded clays, sands and silts (Hawthorn) overlie Limestone (Ocala). B. Dissolution of limestone creates loss of material in subsurface. Overburden subsides to accomodate loss. Tension faults develop as bedding is disturbed, creating dissolution pathways (pipes) and breaches in impermeable layer. Continued deposition onlaps onto original sediment surface. C. Fluctuations in water table or other factors may slow dissolution rates, subsidence decreases or terminates, continued deposition, perhaps fluvial, fills any surface depression and dissolution pipes.
