Modeling Middle Devonian deposition in the Selwyn Basin, Northern Yukon.

Abstract

A Ni-Mo-PGE sulfide deposit (NiMo) in norteastern Yukon occurs at the boundary between Ordovician-Early Devonian Road River and Middle Devonian Earn Group. This research investigated multiple genetic models for basin-wide mineralization. Electron microscopy (SEM and TEM) identified microbial structures, indicating a bacterial influence on sulfide precipitation.
