“…Sinkhole activity is rare in the district. Where observed, it is typically related to dissolution of shell concentrations, particularly mollusks, near the land surface (Upchurch et al, 2015). These are usually expressed as shallow (a few feet, about one meter) cover-settlement features which may form where the undifferentiated Tertiary/Quaternary shelly sediments are present.…”

The accompanying 1:100,000 scale geologic map (Open-File Map Series 111, Plate 1) depicts the areal distribution of bedrock and surficial geologic units for the U.S. Geological Survey (USGS) Bartow 30 x 60 minute quadrangle. The map was constructed using a combination of field mapping (at 1:24,000 scale), compilation of data from existing maps (various scales), core and cuttings analyses and descriptions, and analyses of various Geographic Information System (GIS) data sources. The resulting data were compiled in ESRI ® ArcGIS ® ArcMap™ 10.6.1 software for publication as part of the Florida Geological Survey Open-File Map Series. Mapped units range in age from late Oligocene to Holocene. Important resources in the mapped area include potable groundwater, sand, clay, phosphate, shells, and limestone. Numerous karst features are present in the study area. The geologic map and accompanying plates produced for this area not only provide a greater understanding of the interaction between the geologic units, associated karst, springs, and ecosystems, but have utility as a land management tool for economic development, mineral and energy production, and environmental protection for Florida. Examples include designing new construction projects, siting new water supply wells, wastewater treatment plants, energy production facilities, waste management and storage facilities, locating sources of mineable resources, and protection of springs, surface and groundwater quality.
