Supplementary data for Carlin-type geochemical signal in lake and stream sediments from Kechika trough, north-central British Columbia

by A.S. Rukhlov, T. Han, J. Nelson, A.S. Hickin, and F. Ferri

 

GeoFile 2014-10 provides tables for geochemical analyses of lake- and stream-sediment samples collected by the Regional Geochemical Survey (RGS) and National Geochemical Reconnaissance (NGR) from the Kechika trough, north-central British Columbia and the Rackla belt, east-central Yukon. It serves as a data repository for interpretations presented by Rukhlov et al., 2015.

Appendix 3. Univariate data summary for Regional Geochemical Survey and National Geochemical Reconnaissance lake- and stream-sediment samples from the Kechika trough, north-central B.C. and the Rackla belt, east-central Yukon. The original and standardized data are compared in terms of linear-scale histograms, Tukey box plots and probability plots. The original data were standardized by log-transformation and levelled by sample medium, stream order and underlying bedrock geology at sample site using robust Z-score method. The standardized data are also plotted on regional maps for the Kechika trough and Rackla belt areas. Download (92 MB)
