Mapping the subsurface geometry of the Moyie Anticline, southeastern British Columbia: Implications for mineral

Summary Application of seismic reflection profiling methods to analyzing the regional and detailed structural and stratigraphic features of the Moyie anticline in the Purcell anticlinorium of southeastern British Columbia has provided new perspectives on subsurface variations that may assist in exploration for sedimentary-hosted mineral deposits. The Moyie anticline is the southernmost of a series of north-plunging nested anticlines and is cored by folded Mesoproterozoic Aldridge Formation turbidites of the Belt-Purcell Supergroup that have been intruded by syndepositional mafic Moyie Sills. Aldridge Formation rocks have been productive sources for Pb-Ag-Zn deposits. Mapping of key stratigraphic markers, delineated by extensive, reflective, and correlatable sill horizons, allows identification of time thickness variations that are likely associated with stratigraphic thickness changes that may assist in future exploration efforts.
