Résumé(Sommaire disponible en anglais seulement)
The Banks Island national park has been proposed to include the Thomsen River valley of northeastern Banks Island, and a Canadian Landmark site has been proposed for the southern tip of Banks Island. In order to place these proposed park areas in a regional geological context this Phase 1 resource assessment considers all of Banks Island and north western Victoria Island. The assessment is based on the application of deposit models to regional geological data which were compiled from literature and supplemented by chemical analysis of selected rock and till samples. Two weeks of field investigations allowed spot checking and re-sampling of locations
considered to show mineral potential. Four main geologic domains underlie the study area (Fig. 1): I - Late Proterozoic platformal strata, basalts and related sills of the Amundsen Embayment; II - Cambrian to Late Devonian platformal strata of the Prjnce Albert Homocline; ill - elastic sedimentary rocks of the Banks Basin, an unstable cratonic margin; and IV - unconsolidated fluvial and glacial sediments of the Arctic Coastal Plain. The detailed assessment rating boundaries coincide approximately with the geological domain boundaries, however they cross-cut the domain boundaries in several places. The proposed park areas also cross geological domain and assessment rating boundaries. All resource potential ratings are summarized by geographic area (Figs 1, 2; Table 1). No currently economic mineral or hydrocarbon resources are known in the study area. Moderately high potential (numerical rating of 3 on a scale of 1 to 7, see Table 2) is assigned to sandstone-uranium, to shale-hosted and carbonate-hosted lead-zinc; and to coal in rocks underlying parts of the proposed park areas. Fluid hydrocarbon potential of the northern proposed park area is moderate (4) on land but is moderate-to-high (3) in the immediate offshore. Other commodities are of low to very low potential (6, 7) in the study area. Application of the geologically derived resource-potential ratings to exploration and park boundary decisions would be influenced by a number of economic factors. For example, the moderate-to-high potential (3) for lead-zinc in the Prince of Wales Strait area is enhanced by the proximity to tide-water of nearsurface suitable host rocks. Constraining economic factors apply to ratings in most of the remaining proposed park areas: sandstone-type uranium deposits, if present could be economic but would be relatively low in grade; lead-zinc deposits would occur at depths of 1000 to 3000 m west of Prince of Wales Strait; and the 2-m-thick coal seams, although suitable for local use, might be difficult to exploit on a large scale. Resource assessment ratings are higher in this report than in earlier reports, for example, lead-zinc, (3 versus 7); and uranium, (3 versus not previously considered for Domain ill). These increased ratings underscore the need for periodic reassessment, particularly in poorly known terranes of northern Canada.
