Item Geological Studies Of Cretaceous And Tertiary Section, Test Well Je32-04, Central Delaware(Newark, DE: Delaware Geological Survey, University of Delaware, 1985-06) Benson, R.N.; Jordan, R.R.; Spoljaric, NA cored well 1,422 feet (433 meters) deep drilled two miles southeast of Dover is the basis for this integrated study of the lithology and paleontology of the Cretaceous-Tertiary section in central Delaware. The section is subdivided into lithostratigraphic, biostratigraphic, chronostratigraphic, and heavy mineral units. Data and results are presented on a common base in three plates.Item Stratigraphy Of The Post-Potomac Cretaceous-Tertiary Rocks Of Central Delaware(Newark, DE: Delaware Geological Survey, University of Delaware, 1996) Benson, R.N.; Spoljaric, N.This Bulletin presents the subsurface stratigraphy of the post-Potomac Cretaceous and Tertiary rocks of the Atlantic Coastal Plain of central Delaware, between the Chesapeake and Delaware (C & D) Canal and Dover. Geophysical log correlations supported by biostratigraphic and lithologic data from boreholes in Delaware and nearby New Jersey provide the basis for the report. The stratigraphic framework presented here is important for identifying subsurface stratigraphic units penetrated by the numerous boreholes in this part of Delaware, particularly those rock units that serve as aquifers, because such knowledge allows for better prediction at ground-water movement and availability. Also, accurate stratigraphy is a prerequisite for interpreting the geologic history of the rocks and for the construction of maps that depict the structure and thickness of each unit.
