This book is a comprehensive overview of the ever-captivating field of glaciation from the perspective of glacial landsystems. This approach models the many processes, forms and interactions that can be found in glaciated landscapes throughout the world. Landsystems models allow the glacial geologist and geomorphologist to evaluate these landscapes in relation to the dynamics of glaciation and to climate and geology. Glacial Landsystems brings together the expertise of an international range of specialists to provide an up-to-date summary of landsystems relevant to both modern and ancient glacier systems and also in the reconstruction and interpretation of former glacial environments. The models are applicable at all scales from ice sheets to small valley glaciers. This book is an essential reference for anyone embarking upon research or engineering surveys in glaciated basins and provides a wide-ranging handbook of glacial landsystem types for students of glaciation.
This report results from an investigation of the Quaternary geology & geomorphology of the south half of Melville Peninsula, Nunavut. The purpose of the investigation was to map the area systematically in order to determine the distribution, character, & origin of surface materials and to reconstruct the Quaternary history of the area. The first part provides background information on previous research, bedrock geology, and physiography of the area. The next part describes the nature & distribution of surficial materials & landforms, including information on their physical properties, texture, & composition along with interpretation of their mode of formation. A subsequent section on present geomorphic processes addresses topics of particular interest to environmental concerns & land management. The final section emphasizes those elements that concern mineral exploration, specifically the provenance of till, directions & distances of glacial transport, concentrations of elements in till, and their relationship to bedrock geology.
International Kimberlite Conferences (IKCs) are special events that are held across the world once in four to five years. IKC is the confluence platform for academicians, scientists and industrial personnel concerned with diamond exploration and exploitation, petrology, geochemistry, geochronology, geophysics and origin of the primary diamond host rocks and their entrained xenoliths and xenocrysts (including diamond) to get together and deliberate on new advances in research made in the intervening years. Ever since the organization of first IKC in 1973 and its tremendous success, the entire geological world eagerly look forward to subsequent such conferences with great enthusiasm and excitement. The scientific emanations from IKCs continue to make significant impact on our understanding of the composition, nature and evolution of the planet we live on. The previous conferences were held at Cape Town (1973), Santa Fe, New Mexico (1977), Clermont-Ferrand, France, (1982). Perth, Western Australia (1987), Araxa, Brazil (1991), Novosibirsk, Russia (1995), Cape Town (1998), Victoria, Canada (2003) and Frankfurt, Germany (2008). The tenth IKC was held at Bangalore, India between 5th and 11th February 2012. The conference was organized by the Geological Society of India in association with the government organizations, academic institutions and Indian diamond mining companies. About 300 delegates from 36 countries attended the conference and 224 papers were presented. The papers include 78 oral presentations and 146 poster presentations on following topics: Kimberlite geology, origin, evolution and emplacement of kimberlites and related rocks, petrology and geochemistry of metasomatised lithospheric mantle magmas, diamond exploration, cratonic roots, diamonds, diamond mining and sustainable developments and policies and governance of diamond exploration. Pre- and post-conference field trips were organized to (i) the diamond bearing kimberlites of Dharwar Craton in South India, (ii) lamproites of Bundelkhand Craton in northern India and (iii) diamond cutting and polishing industry of Surat, Gujarat in western India. A series of social and cultural programmes depicting cultural diversity of India were organized during the conference. The Kimberlite fraternity enjoyed yet another socially and scientifically successful conference.
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.
With detailed essays on the Arctic's environment, wildlife, climate, history, exploration, resources, economics, politics, indigenous cultures and languages, conservation initiatives and more, this Encyclopedia is the only major work and comprehensive reference on this vast, complex, changing, and increasingly important part of the globe. Including 305 maps. This Encyclopedia is not only an interdisciplinary work of reference for all those involved in teaching or researching Arctic issues, but a fascinating and comprehensive resource for residents of the Arctic, and all those concerned with global environmental issues, sustainability, science, and human interactions with the environment.
This report completes a project designed to study the Quaternarygeology of central Melville Island including Dundas Peninsula. It contains descriptions of surficial materials together with anoutline of the Quaternary history with particular emphasis onlate Quaternary glacial and marine events. Dundas Peninsula isof particular interest since continental ice sheets reached theirmaximum limits in this area on several occasions. A particularlyimportant reason for examining south-central Melville Island isthe projected routing (at the time of writing) of one or morenatural gas transportation systems through it. Nonetheless, thisstudy is not designed to provide geotechnical information for anyone project, but rather to provide information relevant toengineering, land management, or environmental impact studies, aswell as regional Quaternary studies.
