The data reported here was collected during the 1982-1988 mineral resource assessment of the Port Moller and adjacent quadrangles (see Wilson and others, 1996). Analytical data for virtually all of the samples reported here has been previously published in a series of U.S.G.S. Open-File reports, including Angeloni and others (1985), Arbogast and others (1987), and Wilson and others (1987). Induction-coupled plasma (ICP) data is reported here for the first time on stream sediment samples resulting from analyses conducted by S.E. Church in the early 1990's. We have selected a subset of the Port Moller assessment data for inclusion in this report.
