The spatial databases represent the original content of 43 published geologic maps, provide normalized map unit descriptions, and provide additional information and interpretation not in the original reports.

Geologic map unit and lithologic descriptions used in Open File Report 2005-1235, with extensive bibliographic references to geologic literature that could not be included in the spatial database.

Results of mineral abundance estimates based on Rietveld refinement of X-ray diffraction (XRD) analyses of mill tailings and other ore processing materials from worldwide localities. Data are provided in CSV format.

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 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 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.

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.
