AbstractFieldwork in the summer of 2015 was carried out at various localities in the southern half of Axel Heiberg Island, and focused on volcanic successsions and sub-volcanic intrusive complexes of the High Arctic Large Igneous Province (HALIP). The ~ 950 m thick sequence of basalts of the Strand Fiord Formation occurring east of Plateau Lake represents a world-class exposure of continental flood basalts consisting of thick units of basalt flows that display well-developed colonnades and entablatures. The intrusive complex at Middle Fiord exhibits intrusions with complex geometries, cross-cutting relationships and lithological variability rarely exposed in Large Igneous Provinces (LIPs) of Mesozoic age. Highlights of fieldwork also include field observations and sampling of the Surprise Fiord dyke swarm and the documentation of showings of massive sulphide mineralization in the Expedition Fiord area. Follow-up mapping, geochemistry, mineralogy and U-Pb geochronology will fill critical knowledge gaps on the magmatic history and Ni-Cu-PGE prospectivity of the Canadian portion of the HALIP. Intrusive complexes in the Middle Fiord area, in particular, will provide a unique opportunity to elucidate the architecture and chemical variability of rarely-exposed volcanic feeder systems associated with LIPs.
