GeoFile 2014-05: Stream sediment orientation survey, Aley carbonatite niobium deposit, British Columbia, Canada
Presented as a poster at the annual Mineral Exploration Roundup Conference (2014), Geofile 2014-5 contains the results of a stream sediment orientation survey carried out on the Aley carbonatite complex, the largest and most developed Nb deposit in British Columbia. This study found the +125 μm stream sediment size fraction to be ideal for indicator mineral study. It shows the usefulness of pXRF data in determining downstream trends in pathfinder elements and predicts indicator minerals expected in the stream sediments based on deposit mineralogy. This project received funding from Targeted Geoscience Initiative 4 (2010-2015), a Natural Resources Canada program carried out under the auspices of the Geological Survey of Canada.
