Stream-sediment samples reanalyzed for major, rare earth, and trace elements from seven 1:250,000-scale quadrangles, south-central Alaska, 2007-09 [New Window]
New analyses of 1,075 previously collected stream sediment samples, measuring more elements with better precision. Includes arsenic, gold, palladium, and platinum and 55 major, rare earth, and trace element concentrations.
Stream-sediment samples reanalyzed for major, rare earth, and trace elements from ten 1:250,000-scale quadrangles, south-central Alaska, 2007-08 [New Window]
New data for 366 previously collected stream-sediment samples, because recently developed analytical methods can detect additional elements of interest and have lower detection limits than the methods used when these samples were originally analyzed.
