Geochemical Data Release for Gospel-Hump Wilderness Area, Magruder Corridor and Special Mining Management Zone Additions to the Frank Church River of No Return Wilderness Area, and adjacent areas Idaho and Montana
Geochemical analyses of samples from stream sediments, magnetic heavy-mineral concentrates, nonmagnetic heavy-mineral concentrates, slightly magnetic to nonmagnetic heavy-mineral concentrates, and rocks. All were analyzed by semi-quantitative 6-step emission spectrography. Some of the stream sediment samples were also analyzed by flame-atomic absorption spectrophotometry. Data are provided in Microsoft Access format and as tab-delimited text. |

Water and sediment geochemistry data from the vicinity of Yellow Pine, Idaho
Water characteristics (measured in situ) and laboratory geochemical analysis of water and sediment in this area to quantify the increase in dissolved constituents in streams attributable to historical mining activity. Data are provided in CSV format. |

|
Garnet Lu-Hf Ages and Isotope Data for the Stibnite, Idaho Area
Garnet Lu-Hf ages of the schist of Moores Station Formation and a cross-cutting garnetiferous felsic dike in this area. These ages provide part of the early geologic history leading up to ore deposition. Data are provided in CSV format. |

Isotopic ratios and element concentrations of U-Pb and Sm-Nd for scheelite petrochronology
Instrument, standard, and sample data from application of in situ laser ablation-inductively coupled plasma-mass spectrometry dating of scheelite in thin section, and sample data from isotope dilution thermal ionization mass spectrometry scheelite dating. Data are provided in CSV format. |
