“…weakened the current through the Gulf Trough (Denny et al 1994), and in conjunction with inferred uplift of the Appalachian Mountains (Riggs 1979), contributed to infilling of this seaway. The Gulf Trough was closed by the Late Eocene (Chen 1965), allowing the dispersal of siliciclastics to the eastern part of the Florida Platform, where they mixed with carbonates during the Oligocene to Late Miocene (Scott 1988;Hammes 1992;Brewster-Wingard et al 1997;Missimer 1997;Guertin et al 2000;Cunningham et al 2001a). Throughout the Late Miocene to latest Early Pliocene, deposition of carbonate sediments was negligible, and thick siliciclastic coastal-plain or slope deposits accumulated over most of the eastern side of the Florida Platform (Scott 1988;Cunningham et al 1998;Missimer 1999;Cunningham et al 2001a).…”

Multiple, spatially restricted, partly enclosed karst sub-basins with as much as 100 m of relief occur on a mid-carbonate platform setting beneath the modern estuaries of Tampa Bay and Charlotte Harbor located along the west-central Florida coastline. A relatively high-amplitude seismic basement consists of the mostly carbonate, upper Oligocene to middle Miocene Arcadia Formation, which has been signifi cantly deformed into folds, sags, warps and sinkholes. Presumably, this deformation was caused during a mid-to-late Miocene sea-level lowstand by deep-seated dissolution of carbonates, evaporites or both, resulting in collapse of the overlying stratigraphy, thus creating palaeotopographic depressions.Seismic sequences containing prograding clinoforms fi lled approximately 90% of the accommodation space of these western Florida sub-basins. Borehole data indicate that sediment fi ll is mostly siliciclastic deposited within deltaic depositional systems. The sedimentary fi ll in the Tampa Bay and Charlotte Harbor sub-basins is mostly assigned to the upper Peace River Formation of late Miocene to early Pliocene age. This fi ll is part of a >1000 km long, Tertiary siliciclastic deposit that stretches north-to-south down peninsular Florida. Sediment fi ll of these two sub-basins is linked to erosion and remobilization of pre-existing, middle Miocene quartz-rich sediments via enhanced sediment transport by local, short-length rivers and discharge into coastalmarine depositional environments. Increased sediment discharge possibly resulted from amplifi ed thunderstorm activity and enhanced runoff during a warm period of the Pliocene.Rather than incised valley fi lls or reef-margin, backfi lled basins, Tampa Bay and Charlotte Harbor represent spatially restricted, sediment-fi lled karst palaeotopographic lows. The 'dimpling' of a carbonate platform by karst sub-basins provides a previously unrecognized mechanism for the creation of accommodation that can result in the 'drowning' of a carbonate platform by siliciclastics.

Mixed siliciclastic and carbonate sediments are common in the stratigraphic record, but fully homogenised mixes are not. Many occurrences of mixed sediment sequences are dominated by end‐members with stacking of ‘nearly pure’ lithfacies (e.g. cyclothems containing alternating sandstone, limestone and coal units). The Plio‐Pleistocene sediments within south‐west Florida provide insights into the occurrence of fully homogenised siliciclastic/carbonate deposits. In all defined environments from lagoon to supratidal to inner tidal to beach to offshore to coral reef, quartz sand coexists with carbonates. Perhaps the key feature that allowed full homogenisation of the sediments within all facies and subfacies was the relatively shallow water (<10 m), which facilitated mixing during low‐order eustatic sea‐level events and storms. However, four factors contributed to the full homogenisation of the sediment types without termination or inhibition of carbonate organism growth. These factors are (1) the shallow water allowing wave‐driven sediment transport (all environments within the wave orbital depth), (2) close proximity and perhaps irregular nature of the depositional environment boundaries, (3) low influx rate of quartz sand via longshore transport, and (4) the lack of significant terrigenous mud transport into the system. Mixing processes at the large‐scale included movement of sediments from one depositional environment to another during storms, mixing along facies boundaries, and in situ mixing within autochthonous and parautochthonous mollusc death assemblages. At the smaller scale, mixing occurred by bioturbation and diagenetic dissolution of carbonate skeletal grains during minor high sea‐level stands.
