 | | Although these local variations in sedimentary facies and sedimentation rates existed, the Permian basin was also subjected to broadly regional subsidence, resulting in the accumulation of between 2,100 and 4,200 m (7,000 and 14,000 ft) of Permian clastic terrigenous, carbonate, and evaporite strata (McKee et al., 1967). |
 | | Permian sandstone units do not thin over the pisolite facies so that it is unlikely that this facies was itself an elevated barrier as required by caliche hypotheses thus a back-barrier seepage area fits the topographic constraints. |
 | | Likewise, the Permian facies suite of fore-reef debris, reef, back-reef rubble, near-back-reef skeletal sands and muds, islands, restricted lagoons, and finally supratidal deposits is remarkably similar to the general facies spectrum found in the Florida Keys-Florida Bay area (Ginsburg, 1964; Purdy, 1963). |
