Geochemical trace-element and rare-earth element data from rock samples collected in 2012 on Annette Island, southeast Alaska
Description
Personnel from the Alaska Division of Geological & Geophysical Surveys (DGGS) conducted a reconnaissance rock sampling project from April 30 to May 4, 2012, to obtain modern, quantitative geochemical analyses to characterize select mafic-ultramafic rocks and one chalcopyrite-bearing quartz vein sample from Yellow Hill on Annette Island, in the Ketchikan Quadrangle, southeastern Alaska. Highlights of this sampling project include mafic-ultramafic rock samples with up to 0.079 ppm platinum (Pt) and 0.123 ppm palladium (Pd), and a quartz vein with 2.83 percent copper (Cu) and 0.155 ppm gold (Au).
