These data contain concentrations of major and trace elements in quality-assurance samples.These are the machine-readable versions of Tables 2–5 from the U.S. Geological Survey Scientific Investigations Report, Distribution of Mining Related Trace Elements in Streambed and Floodplain Sediment along the Middle Big River and Tributaries in the Southeast Missouri Barite District, 2012-15 (Smith and Schumacher, 2018). Table_2 contains concentrations of major and trace elements in regular and replicate streambed-sediment samples in samples BR-02 and BR-04. Each sample was sieved and analyzed for concentrations within the less than 2-, less than 0.250-, and less than 0.063-mm size fraction. Averaged relative percent...

These data contain concentrations of trace elements in unsieved flood-plain samples collected along tributaries draining the Washington County Barite District. This is the machine-readable version of Table 9 from the U.S. Geological Survey Scientific Investigations Report, Distribution of Mining Related Trace Elements in Streambed and Floodplain Sediment along the Middle Big River and Tributaries in the Southeast Missouri Barite District, 2012-15 (Smith and Schumacher, 2018).

These data contain concentrations of trace elements in various size fractions (less than 0.063 millimeters, 0.063 to 0.250 millimeters, 0.250 to 2 millimeters, and greater than 2 millimeters) of flood-plain core samples analyzed by inductively coupled plasma mass spectrometry (laboratory) and x-ray fluorescence (U.S. Environmental Protection Agency). This is the machine-readable version of Table 6 from the U.S. Geological Survey Scientific Investigations Report, Distribution of Mining Related Trace Elements in Streambed and Floodplain Sediment along the Middle Big River and Tributaries in the Southeast Missouri Barite District, 2012-15 (Smith and Schumacher, 2018).

These data contains location information for the various sites covered in the data release. Locations include streambed-sediment, flood-plain core, and flood-plain sediment sampling locations along the Big River, Maddin Creek, Mineral Fork Creek, Old Mines Creek, Mill Creek, and Dry Creek. This is the machine-readable version of Table 1 from the U.S. Geological Survey Scientific Investigations Report, Distribution of Mining Related Trace Elements in Streambed and Floodplain Sediment along the Middle Big River and Tributaries in the Southeast Missouri Barite District, 2012-15 (Smith and Schumacher, 2018).

These data contain concentrations of select trace elements in samples collected on the flood plain from flood deposits from the December 2015 flood and underlying soils. All samples were analyzed by x-ray fluorescence. This is the machine-readable version of Table 10 from the U.S. Geological Survey Scientific Investigations Report, Distribution of Mining Related Trace Elements in Streambed and Floodplain Sediment along the Middle Big River and Tributaries in the Southeast Missouri Barite District, 2012-15 (Smith and Schumacher, 2018).

This U.S. Geological Survey (USGS) Data Release contains locations and concentrations of metals in various size fractions in floodplain-core, streambed-sediment samples, and sediment deposited on the flood plain from the December 2015 flood and underlying soils collected from along the Middle Big River and tributaries in the Southeast Missouri Barite District from 2012 to 2015. All samples were analyzed either by inductively-coupled plasma-mass spectrometry (ICP-MS) or x-ray fluorescence (XRF). Concentrations of metals in quality-assurance samples are also presented to evaluate the effect of sample splitting and compare the U.S. Environmental Protection Agency (EPA) and USGS Missouri Water Science Center XRF units....

These data contain concentrations of major and trace elements measured by inductively coupled plasma mass spectrometry at the laboratory of various size fractions (less than 0.063, less than 0.250, and less than 2 millimeters) from the middle Big River and tributaries draining the Barite District. This is the machine-readable version of Table 7 from the U.S. Geological Survey Scientific Investigations Report, Distribution of Mining Related Trace Elements in Streambed and Floodplain Sediment along the Middle Big River and Tributaries in the Southeast Missouri Barite District, 2012-15 (Smith and Schumacher, 2018).
