Magnetic Tape Containing Trace Element Data for Rock, Stream-Sediment, and Stream-Sediment Heavy-Mineral Concentrate Samples from the Bradfield Canal Quadrangle, Southeastern Alaska

摘要

Magnetic tape containing geochemical data from rock, stream-sediment, and stream-sediment heavy mineral concentrate samples collected in the Bradfield Canal quadrangle, southeastern Alaska. Three files contain data from 2784 rock samples, 1295 stream-sediment samples, and 219 stream-sediment heavy-mineral concentrate samples respectively. Data includes analyses for up to 31 elements by emission spectroscopy and up to 5 elements by atomic absorption techniques and geodetic coordinates in decimal degrees. Rock samples are labelled with the rock type sampled. Text (23 pages) describes sampling procedures and lists references.
