AbstractHyper-enriched black shale (HEBS) deposits are a globally important resource for base-, strategic- and precious-metals. In northern Yukon, thin (3 to 40 cm-thick) HEBS deposits occur sporadically over 1000s of km2 at the Road River Group-Canol Formation contact. The deposits in each location share lithological and geochemical characteristics (particularly Ni-Zn-Mo-PGE enrichment). Despite decades of research, there is little consensus on how these formed. Exploration for HEBS mineralization is hampered due this poor understanding; however, through ongoing research, we aim to develop a genetic model that accounts for the salient features within these deposits.
Summary(Plain Language Summary, not published)
The extended abstract an poster presentation highlights ongoing research in shale-hosted Nickel-Zinc-Platinum group element mineral deposits that occurs in northern Yukon. We present a combination of bulk rock geochemistry and mineral chemistry, and our ongoing research will focus on elucidating how these deposits formed.
