2 GEOLOGICAL SURVEY SECTION The Geological Survey Section examines, surveys and maps the geology, mineral resources, and topography of the State to encourage the wise conservation and use of these resources by induscry, commerce, agriculture and government agencies for the general welfare of the citizens ofnonh Carolina -. The Section conducts basic and applied research projects in environmental geology, mineral resources exploration and systematic geologic mapping. Services include identifying rock and mineral samples submitted by citizens and providing consulting services and specially prepared reports to agencies that need geological infonnation. The geological Survey section publishes Bulletins, Economic Papers, Infonnation Circulars, Educational Series, Geologic Maps and Special Publications. For a list of publications or more information about the Section contact the Geological Survey Section, Division of Land Resoun:es, at Post Office Box 27687, Raleigh, Nonh Carolina Jeffrey C.

3 Listing of Concentrations of Variables of Stream Sediment, Stream Water, and Groundwater for the Laurinburg and Florence 30 x 60 - Minute Quadrangles -NURE Database by Robert H. Carpenter and JetTrey C. Reid INTRODUCTION o This report is a compilation ofgeochemical data for stream sediment and groundwater for the Laurinburg and Florence30 x 60 - minute quadrangles (Figure 1). Maps and tables were preparedfrom statewide data obtained by the Savannah River Laboratory under sponsorship of the U.S. Dept. of Energy in its National Uranium Resources Evaluation (NURE) program ~Sargent and others, 1982). Sampling and analysis were performed during the period Because ofthe large size ofthe database, the North Carolina Geological Survey is presenting thp, database in both statewide and 30 x 60 - minute quadrangle formats. Statewide formats currently available include atlases ofstream sediment and hydrogeochemical data which contain maps showing quartile distribution of concentrations of variables (Reid, 1991; Reid, 1993). Reid and Carpenter (l993a, 1993b) present listings ofconcentrations ofvariables which equal or exceed the 90th percentile (and ph and conductivity below the 10th percentile) for stream sediment and groundwater-stream water. This open-file report is part ofa series ofreports that present sample-location maps and listings of analyses ofall variables in all of the 30 x 60 - minute quadrangles that comprise the state ofnorth Carolina. Subsequent reports will review the NURE data for individual 30 x 60 - minute quadrangles. These reviews will contain the following: 1) maps showing concentrations ofall the variables in up to eight class intervals; 2) geologic review of the quadrangle and discussion of relationship of geochemical variables to rock units and structural features; 3) review of mineral resources and discussion ofrelationship ofgeochemical variables to mineral occurrences; and 4) discussion ofoutliers that may relate to anthropogenic contamination. In this report, site-location maps use state boundaries, county boundaries and minute quadrangle boundaries as references to site-locations. The North Carolina Index to 1'QPOi:raphic and Other Map Coverqe, prepared by the U.S. Geological Survey, is a useful reference document. The List ofpublications ofthe North Carolina GeoIQ&ica1 Survey indicates areas within the state for which some geologic and geophysical maps, and reports, are available. Listings in this report are in the same basic format as those presented in microfiche by Sargent i

4 and others (1982). Column 1 lists the laboratory numbers applied to each analyzed sample. Column 2 lists site identification codes. The first two characters are the codes for the county name. The next three digits are sample numbers. They are listed sequentially for each county in the order they were collected. The next two columns list the latitude and longitude ofthe sampling sites in decimal degree format. The remaining columns are data columns and analyses are given in parts per million (stream sediment) and partsper billion (groundwater). In these columns, a minus (-) sign indicates that a value is below the detection limit. Ifbackground is high, and an accurate estimate ofminimum detection limit could not be made, a period (.) indicates that the element was not detected and that the detection limit is unusually high. Missing data are denoted by the letter "M". For gold, analyses are listed only for those samples in which gold was detected. For arsenic, a value of0is assigned for samples in which arsenic was analyzed, but not detected. For stream sediment, two listings are presented. The frrst listing is for elements analyzed by neutron activation as well as field measurements for ph and conductivity ofstream water. Variables included in this listing are ph, conductivity, uranium (U), thorium (Th), hafnium (Hf), cerium (Ce), iron (Fe), manganese(mn), sodium (Na), scandium (Sc), titanium (Ti), vanadium (V), aluminum (AI), dysprosium (Dy), europium (Eu), lanthanum (La), samarium (Sm), ytterbium (Yb), and lutetium (Lu). The second listing is for supplemental elements analyzed by a variety oftechniques. These include extractable uranium (Ox), silver (Ag), arsenic (As), barium (Ba), beryllium (Be), calcium (Ca), cobalt (Co), chromium (Cr), copper (Cu), potassium (K), lithium (Li), magnesium (Mg), molybdenum (Mo), niobium (Nb), nickel (Ni), phosphorous (P), lead (Pb), selenium (Se), tin (Sn), strontium (Sr), tungsten (W), yttrium (Y), and zinc (Zn). Stream sediment analyses are for the minus 100 mesh fraction «149 microns) unless otherwise noted. Groundwater, normally samples ofwater from wells, was also analyzed by neutron activation. Field measurements were made ofph and conductivity. Variables included in listings ofgroundwater analyses includeph, conductivity, uranium (U), bromine (Br), chlorine (CI), fluorine (F), magnesium (Mg), manganese (Mn), sodium (Na), vanadium (V), uranium/conductivity, aluminum (Al), and dysprosium (Dy). Stream water was also analyzed for these variables at 295 sites in North Carolina. Listings for stream water are included for areas in which these sites are located. Although the data was acquired with considerableattention to quality control, some errors exist. These include uncertainties ofsample locations due to the use ofcounty road maps as base maps for field use and digitizing sampling sites. Malfunction offield equipment used in measurement ofph and conductivity has also been recognized in some areas. Some ofthe analyses are also in error. Some ofthese errors are apparent when concentrations show systematic "breaks" at county boundaries. This suggests that conditions of analysis for different batches of samples were not uniform. In general, analyses ofstream sediment by neutron activation are more reliable than analyses ofsediment by other supplemental methods. Fora number ofcounties, supplemental analyses were not made. Thus elements ofinterest for mineral exploration and environmental geochemistry are lacking for large areas.
