Abstract(Summary)
Natural Resources Canada (NRCan) has been tasked, under the Marine Conservation Targets1 (MCT) initiative announced in Budget 2016, with evaluating the petroleum resource potential for areas identified for protection as part of the Government of Canada's commitment to conserve 10% of its marine areas by 2020. As part of this initiative, Parks Canada Agency (PCA) requested that NRCan conduct a qualitative petroleum resource assessment for an area of eastern Hudson Bay and James Bay, within which a National Marine Conservation Area (NMCA) may be evaluated. This report provides the results of the qualitative petroleum resource assessment completed by NRCan's Geological Survey of Canada (GSC) for the study area of eastern Hudson Bay and James Bay. The GSC interpretation is visually represented by a qualitative petroleum potential map (Figure 1). Data were compiled and assessed for an area that is larger than what was requested by PCA based on practical geological considerations (Figure 2). This approach improves the detail and accuracy of GSC predictions. The GSC report will be used as part of PCA's decision-making process for any future NMCA in the study area.
The sedimentary basins that could contain petroleum potential in the study area are:
1.Eastern Hudson Bay (Belcher Basin). This region is comprised of thick Proterozoicsedimentary, low-grade metamorphic, and igneous rocks. The area is characterized bycompressional deformation during the Trans-Hudsonian Orogeny.
2.James Bay. This region encompasses the eastern margins of the Moose River Basin,a Paleozoic carbonate basin with its depocentre located in onshore Northern Ontario.The Paleozoic sediments of the Moose River Basin are considered the most prospectivesequence from a petroleum exploration perspective; however, petroleum potential isconsidered low.
When considered from a national or global petroleum-basin perspective, both the Belcher andoffshore Moose River basins are interpreted to have very low petroleum potential.
A secondary objective of this study was to summarize the potential for unconventional energy possibly including: gas hydrates, coal-bed methane, oil shale, and shale gas. Unconventional resource potential is considered very low in offshore parts of the study area. Oil shale and coal-bed methane may be prospective unconventional resources in onshore parts of the Moose River Basin (Appendix A). There is no evidence of gas hydrates in this study area.
A tertiary objective of the study is to identify areas with non-petroleum, resource potential (Appendix B). This was accomplished through literature review (Appendix C) and geologic interpretation over a regional scale. Mineral resources identified onshore, that may extend offshore include: limestone, lead, zinc, nickel, copper, iron, fluorite, barite, silver, gold, coal, chromite, lithium, gypsum, peat, granite carving stone, and micro-diamonds. Viability of offshore mineral resources requires that a regulatory framework is established allowing offshore mineral mining in Canada. Figure 3 provides information on mineral occurrences and mines near the study area.
