Generalized structure contour maps of the New Jersey coastal plain
Twelve generalized structural contour maps were prepared from a study of 169 well
logs or sample logs of drill cuttings from the Coastal Plain of New Jersey, Delaware, and
the E astern Shore of Maryland. The configuration of the tops of the nonmarine Cretaceous
deposits (Patuxent , Patapsco, Raritan, and Magothy formations) and the Piney Point Formation
(Eocene) show the known subsurface extent of

Chromite and other mineral deposits in serpentine rocks of the Piedmont Upland, Maryland, Pennsylvania, and Delaware
The Piedmont Upland in Maryland, Pennsylvania, and Delaware is about 160 miles long and at the most 50 miles wide. Rocks that underlie the province are the Baltimore gneiss of Precambrian age and quartzite, gneiss, schist, marble, phyllite, and greenstone, which make up the Glenarm series of early Paleozoic (?) age. These are intruded by granitic, gabbroic, and ultramaflc igneous rocks. Most of th

Ground-water resources in the tri-state region adjacent to the Lower Delaware River
The purpose of this report is to appraise and evaluate the groundwater resources of a tri-state region adjacent to the lower Delaware River that is centered around Philadelphia, Pa., and Camden, N. J., and includes Wilmington, Del., and Trenton, N.J. Specifically, the region includes New Castle County, Del.; Burlington, Camden, Gloucester, Mercer, and Salem Counties in New Jersey; and Bucks, Chest

The trend of suspended-sediment discharge of the Brandywine Creek at Wilmington, Del., 1947-1955
This report presents an analysis and evaluation of the trend of the sediment yield for the Brandywine Creek at Wilmington, Del., for the period from December 1946 to September 1955. The interest in such an analysis and evaluation stems from the efforts of the Brandywine Valley Association and others to reduce erosion and improve land use in the watershed.
The data used for the analysis were taken

Records available to September 30, 1956, on use of water in the Delaware Basin Project area
The purpose of this report is to summarize data on the use of water in the Delaware Basin Project area (fig. 2) and to list the principal data sources that are available in published form. The tables and bibliography will assist Geological Survey personnel assigned to the Delaware Basin Project in evaluating the scope and deficiencies of previous studies of the basin. Information is also given on

Engineering materials of northern New Castle County
This investigation was undertaken to locate deposits of rock, sand, gravel, fill and borrow in northern New Castle County which may be potential sources of material for highway construction, and to prepare maps and descriptions of the surficial earth materials relative to their geologic and engineering properties.

A search for aquifers of sand and gravel by electrical-resistivity methods in north-central New Castle County, Delaware
A search for aquifers in an area immediately north of the Chesapeake and Delaware Canal in New Castle, Del., has been made by an electrical resistivity study. The search located 32 sites that may be underlain by sand and gravel. The thicker deposits are significant with respect to the occurrence of ground water, and all of them are of interest as possible sources of sand and gravel for constructi
