Abstract

The genesis of the Mississippi Valley-type (MVT) lead-zinc mineralization in the Tara Mine at Navan, Ireland and of the mineralization at Robb Lake in northeastern British Columbia has been disputed, in part because their ages are undefined. Timing of fluid flows in southeastern British Columbia is crucial to the understanding of the geologic evolution of the Western Canada Sedimentary Basin (WCSB) and major ore bodies found within it. Paleomagnetism will be used to date the mineralization and dolomitization of the Navan and Robb Lake study areas and of the dolomitization in southeastern British Columbia. The Navan orebody is hosted in Mississippian (Tournaissian) carbonates of the Navan Group. Host rocks of the Robb Lake mineralization are Lower and Middle Devonian platform carbonates of the Muncho-McConnell and Stone formations. The dolomitization in southeastern British Columbia occurred in the middle Cambrian Chancellor carbonates. Oriented block samples were collected at each site from Navan, Robb Lake and southeastern British Columbia. Detailed thermal and AF step demagnetization measurements were conducted as well as saturation isothermal remanent magnetization tests. (Abstract shortened by UMI.)Dept. of Earth Sciences.
