This report contains geochemical data gathered in the Ashland and Rice Lake 1 degree x 2 degree quadrangles in northern Wisconsin and adjacent parts of northern Michigan and Minnesota. The data, in part, is focused on the Chequamegon National Forest. Nine files are presented which contain more than 2,600 multi-element analyses of soils, stream sediments, and lake-bottom sediments.
Data include a mixture of newly acquired data by the USGS and previously reported data from the National Uranium Resource Evaluation (NURE) program. The report thus provides a single-source summary in similar and consistent format of a majority of currently available analyses of surficial materials in this region. Files are presented in DBF format which can be readily imported to GIS programs such as Arcview, and as MS-Excel spreadsheets.
The files include:
A_soil--326 analyses of A-horizon soils (new USGS data)
B_soil--44 analyses of B-horizon soils (new USGS data)
C_soil--455 analyses of C-horizon soils (new USGS data)
E_soil--35 analyses of E-horizon soils (new USGS data)
USGS_ls--96 analyses of lake-bottom sediments (new USGS data)
NURE_ls--361 analyses of lake-bottom sediments (NURE data)
NURE_original--913 analyses of stream sediments (NURE data)
NURE_rean--400 reanalyses of NURE stream sediments (new USGS data)
NUREss_adj--913 stream sediment analyses from the NURE data recalculated based on comparison with NURE_rean results
Together, these data serve to describe the complexity of the surficial geochemical landscape of the glaciated terranes of this part of the Lake Superior region. Both graphic displays, as in Arcview, and statistical analyses can be conducted to meet a variety of end-user needs and address a multitude of environmental and resource issues.
