Book Description
This map synthesizes the field observations and initial interpretations for the Terra Nivea 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 full range of siliciclastic and minor carbonate rock types can be traced to the easternmost tip of Meta Incognita Peninsula. The distribution and eastern limit of high-grade felsic and mafic plutonic rocks, tentatively interpreted as part of the middle Paleoproterozoic Cumberland Batholith, were delineated. Three distinct phases of deformation and one metamorphic episode 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.

Book Description
First published in 1985, Quaternary Environments represents the culmination of Quaternary research in the region of Baffin Island, Baffin Bay and West Greenland over a period of twenty years and it will serve as a timely and complementary balance to the paleo- oceanographic studies in the NE North Atlantic. The region of Baffin Island, Baffin Bay and West Greenland is probably the best place in the world to examine the interactions between ice, land and oceans on timescales of a few hundred to many thousands of years. Two introductory chapters outline the history of research and the physical background. In Part II the evidence for glacial erosion and deposition over the eastern Canadian Arctic is examined and the history of the Baffin Island continental shelf is described. Part III deals with the paleo- oceanography of Baffin Bay and the Labrador Sea through an examination of deep-sea cores dated by several different methods. In Part IV there is a comprehensive account of the stratigraphy of Baffin Island, Bylot Island, and West Greenland, from the Pliocene to the late Wisconsin. Part V examines the climatic effects of the past 10,000 years, considering evidence from pollen analysis, glacier fluctuations, changes of sea level and the response of early (Eskimo) man. This important volume will interest all quaternary scientists, especially those in glaciology, glacial geology, marine geology, and geomorphology.

Book Description
This map synthesizes the field observations and initial interpretations for the Pritzler Harbour 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 Pritzler Harbour 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.

Book Description
This report presents the first comprehensive summaries of Quaternary geology and landscape evolution for the Melville Peninsula, glaciated by the Wisconsin Laurentide Ice. After an introduction on the bedrock geology and physiography of the study area, sections of the report describe the area's surficial materials and landforms, including till, glaciofluvial and glaciolacustrine deposits and landforms, marine deposits and landforms; dispersal trains and ice dynamics; glaciation and ice flow in the study area; deglaciation of the various parts of the peninsula; glacial and postglacial sea-level changes, and their interpretation; the regional context of glaciation and sea-level change; the economic and environmental geology of Quaternary materials such as permafrost and patterned ground forms; postglacial faulting and neotectonics; and till geochemistry, with reference to drift prospecting models.

Book Description
"This report describes the surficial geology of 64,000 km2 of Canada's most northern mainland and complements of a similar report on Somerset Island which lies immediately north of Boothia Peninsula being separated from it by the very narrow waters of Bellot Strait. The report discusses the potential use of geological information to future land use projects and to mineral exploration and presents new interpretations regarding the structure and dynamics of the northern part of the last ice sheet to cover Canada." --

Book Description
This synthesis of the Quaternary geology of Canada and Greenland covers the regional Quaternary geology of Canada, applied Quaternary geology in Canada (including its influence on man's environment), the Quaternary geology of the ice-free areas of Greenland, and the dynamic and climatic history of the Greenland ice-sheet.
