Contents

This open file contains geochemical data for stream sediment and water samples collected in the Duggan Lake-Ellice River area in the administrative region of Kitikmeot, Nunavut.  Mineral grains identified in the heavy mineral fraction of stream sediments are reported.  Samples of sediments and waters were collected in 2012 and 2014 from streams and rivers within parts of National Topographic System map sheets 76-H and 76-I.
