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. |
