Book excerpt: This map summarizes the field observations for the Sylvia Grinnell Lake (north) map area following eight weeks of regional and targeted bedrock mapping on western Hall Peninsula. The 2015 field campaign completes a two-decade mission to update map coverage for the whole of Baffin Island south of latitude 70°N. The bedrock is dominated by a Paleoproterozoic metaplutonic suite, ranging in composition from gabbro to syenogranite, with crosscutting relations indicating a progression from mafic to silicic magmatism. Prevailing upper amphibolite to lower granulite facies metamorphic conditions overlap the stability limits of magnetite and orthopyroxene, which is consistent with equilibrium phase diagrams and regional aeromagnetic data. Metasedimentary rocks, including quartzite, pelite, marble, and metagreywacke, are present as screens and enclaves between and within plutonic bodies. An examination of the 'ghost' stratigraphy suggests that the metasedimentary rocks can be correlated with the middle Paleoproterozoic Lake Harbour Group in the south and Piling Group in the north. Two basaltic dyke swarms and shallowly dipping Ordovician limestone respectively crosscut and overly the Paleoproterozoic units.

Book excerpt: This map synthesizes the field observations and initial interpretations for the Grinnell Glacier area following five weeks of regional and targeted bedrock mapping on the eastern Meta Incognita Peninsula, Baffin Island, Nunavut. Under the Geo-mapping for Energy and Minerals (GEM) Program, this area was targeted in 2014 to upgrade the geoscience knowledge and document the economic potential of the greater Iqaluit area south of Frobisher Bay. Field observations have constrained the distribution of metasedimentary units comprising quartzite, marble, psammite, pelite, and semipelite, all of which can be correlated with the contiguous middle Paleoproterozoic Lake Harbour Group in the type area north of Kimmirut. The spatial distribution of a suite of layered mafic to ultramafic sills intrusive into the sedimentary strata in the western portion of the Grinnell Glacier map area was also documented and will be the focus of further study. Layering in the sills was observed on the centimetre to metres scale, with many bodies containing disseminated sulphide, some associated with ferricrete. The distribution of high-grade felsic and mafic plutonic rocks, tentatively interpreted as part of the middle Paleoproterozoic Cumberland Batholith, were delineated. Four distinct phases of deformation and two metamorphic episodes were recognized. The deformation and metamorphic events can be correlated with similar features and assemblages previously documented both on Baffin Island and on the Ungava Peninsula of northern Quebec, and will be utilized to compare, and improve on, existing regional tectonic models.

This book was released on 2000 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Describes the geology of an area covering about 82,000 square kilometres in north central Baffin Island, beginning with an introduction on the area's location, access, physiography, climate, general geology, and previous studies. Subsequent chapters cover the geology of the Archean to Cretaceous and Recent formations, regional geochemistry, regional geochronology, regional & contact metamorphism, economic geology, and structural geology. The final chapter is a regional synthesis with general comments on structural subdivisions, the nature of their boundaries, regional correlations, and geological history.

Available in PDF, EPUB and Kindle. Book excerpt: The Hall Peninsula Integrated Geoscience Program was led by the Canada-Nunavut Geoscience Office, and was designed to increase the geoscience knowledge and assess the economic potential of the area. Eastern Hall Peninsula is dominantly underlain by Archean tonalite to quartz diorite orthogneiss, while Paleoproterozoic supracrustal and intrusive rocks are exposed to the west. The supracrustal rocks are dominated by pelitic, psammitic, amphibolite and calc-silicate units, are interpreted as correlative with the Lake Harbour Group, and are cut by granulite-grade monzogranite to diorite intrusions. Hall Peninsula records three phases of metamorphism and deformation associated with the Trans-Hudson Orogen that have produced thickskinned, east-verging fold and thrust structures and amphibolite to granulite facies mineral assemblages. Hall Peninsula hosts a highly prospective diamond kimberlite field, as well as mafic and carbonate supracrustal rocks, and ultramafic intrusions that may contain base and/or precious metal, semi-precious gemstone and carving stone resource potential.
