Contents

This Geological Survey of Canada Open File presents geochemical data for stream sediment and water as well as indicator minerals collected on Axel Heiberg Island, Nunavut during the summer of 2015.  The data were collected under the GEM Program’s- Western Arctic’s High Arctic Large Igneous Province activity to evaluate the mineral prospectivity of various geological environments within the east-central Sverdrup Basin.

Field Data	Site specific field observations including geographic coordinates (lat/long – NAD83)

SS_Geochem	Analytical data for the <177 µm size fraction of stream silt sediment. Samples underwent two separate analyses,1- “near-total” 4-acid digestion followed by ICP-MS/ES analysis (60 elements reported) and 2- “partial” aqua-regia digestion followed by ICP-MS/ES analysis (53 elements reported).

	SS_Carbon
Analytical data of the stream silt sediment samples (<177 µm size fraction) for carbon content.  Data for total, inorganic and organic carbon and Loss-on-ignition (LOI) are reported.  

	SS_Munsell			
Munsell analysis of the stream sediment (<177 µm fraction).

			SS_Grain Size
Grain size analysis of the stream sediment (<2.0 mm fraction).
				
SW_FA
Analytical data for filtered and acidified stream water by ICP-MS/ES (62 elements are reported).

	SW_UA
Analytical data of un-filtered and acidified stream water by ICP-MS/ES (62 elements are reported).

SW_FU
Analytical data of filtered and un-acidified stream water by ion chromatography for anions, by titration for alkalinity and by combustion for dissolved organic carbon. Also includes laboratory measurements for pH and conductivity.  Eight variables are reported.

	SW_InSitu
In-situ stream water parameters measured with a YSI ProPlus Multi Parameter meter.

BS_Description	Data for bulk stream sediment samples as received and a description of the raw material prior to processing.

			BS_Processing
Processing weights for each step in refining the heavy mineral concentrate (HMC) of the <0.25 mm fraction and the 0.25 to 2.0 mm fraction.

BS_Geochem	
Analytical data for the pulverized <0.25 mm non-magnetic heavy mineral fraction from stream sediment. Samples underwent two separate analyses,1- “near-total” 4-acid digestion followed by ICP-MS/ES analysis (60 elements reported) and 2- “partial” aqua-regia digestion followed by ICP-MS/ES analysis (53 elements reported).			
BS_Panning
Panning data for gold grain counts as well as other observed metallic minerals.

BS_MMSIMs	
Mineral grain counts for magmatic massive sulphide indicator minerals from the 0.25 to 0.5 mm HMC fraction.
BS_KIMs	
Mineral grain counts for kimberlite indicator minerals from the 0.25 to 2.0 mm HMC fraction.

	BS_100 grain counts
100-grain mineral counts reported as percent composition of the 0.25 to 0.5 mm non-magnetic fraction.

SEM-MLA Analysis
Scanning Electron Microscope - Mineral Liberation Analysis data.  Quantitative analysis of heavy minerals in the 125 to 180 µm fraction.
