This dataset consists of shapefiles that are digitized contours of the structure of Cenozoic and late Cretaceous strata along the Gulf and Atlantic Coastal plains from Texas to New Jersey, not including Maryland and Delaware. Well depths and seismic profiles indicating depth to or elevation of subsurface geologic contacts present in some datasets have also been digitized. Metadata files (.xml) describing each dataset are present within the SHP.zip file subdirectories. Original ArcGIS rasters and overlays from which the contours were digitized are available in the TIF.zip file subdirectories.
Digitized datasets are:
