Stream-sediment samples reanalyzed for major, rare earth, and trace elements from ten 1:250,000-scale quadrangles, south-central Alaska, 2007-08

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.
