Westerly derived Early Cretaceous gold paleoplacers in the Western Canada foreland basin, southwestern Alberta: tectonic and economic implications

Description :
This paper presents evidence for the occurence of detrital gold in fluvial sediments of Albian (Early Cretaceous) igneous-clast conglomerate lenses in the upper Beaver Mines and Mill Creek formations (Blairmore Group). The AA. show how this unusual occurence has arisen as a consequence of the tectonic development of the eastern Canadian Cordillera. The results indicate local gold assay values exceeding those reported elsewhere in the province in either placers or paleoplacers.
