This paper reports the results of a mapping program in the vicinity of the Boston gold deposit near Hope Bay, south-west Nunavut. It first reviews the regional geology, the granitoid rocks of the Hope Bay volcanic belt, and their contact relationships with the belt. It then focusses on the geology of the deposit area, with descriptions of the rock types, the geologic structures, and the gold mineralization. Finally, implications of the findings for mineralization in other areas of the Hope Bay belt are discussed.
The purpose of this paper is to document results of the electrical resistivity characteristics of rocks from the Astarte River Formation, central Baffin Island, for use in interpreting ground electromagnetic surveys that have been conducted in the central Baffin region. Results are presented for five black graphitic shale samples subjected to three-dimensional electrical resistivity measurements & subsequent data analysis. The samples were selected to characterize the resistivity of the Formation and to determine the effect of strong foliation containing porous layers & of disseminated sulphide mineralization oriented parallel to foliation.
The study of estuaries and coasts has seen enormous growth in recent years, since changes in these areas have a large effect on the food chain, as well as on the physics and chemistry of the ocean. As the coasts and river banks around the world become more densely populated, the pressure on these ecosystems intensifies, putting a new focus on environmental, socio-economic and policy issues. Written by a team of international expert scientists, under the guidance of Chief Editors Eric Wolanski and Donald McClusky, the Treatise on Estuarine and Coastal Science, Ten Volume Set examines topics in depth, and aims to provide a comprehensive scientific resource for all professionals and students in the area of estuarine and coastal science Most up-to-date reference for system-based coastal and estuarine science and management, from the inland watershed to the ocean shelf Chief editors have assembled a world-class team of volume editors and contributing authors Approach focuses on the physical, biological, chemistry, ecosystem, human, ecological and economics processes, to show how to best use multidisciplinary science to ensure earth's sustainability Provides a comprehensive scientific resource for all professionals and students in the area of estuarine and coastal science Features up-to-date chapters covering a full range of topics
"The science of informatics in the broadest sense has been several thousands of years in the making. With the recent emergence of large storage devices and high-speed processing of data, it has become possible to organize vast amounts of data as digital products with ontologic tags and concepts for smart queries. Coupling this computational capability with earth science data defines the emerging field of geoinformatics. Since the science of geology was established several centuries ago, observations led to conclusions that were integrative in concept and clearly had profound implications for the birth of geology. As disciplinary information about Earth becomes more voluminous, the use of geoinformatics will lead to integrative, science-based discoveries of new knowledge about planetary systems. Twenty one research papers, co-authored by 96 researchers from both earth and computer sciences, provide the first-ever organized presentation of the science of informatics as it relates to geology. Readers will readily recognize the vast intellectual content represented by these papers as they seek to address the core research goals of geoinformatics."--Publisher's website.
Dedicated to Bob Hatcher, this Memoir explores linkages between tectonic processes through a series of field-, numerical- and laboratory-based studies, concentrating on feedback mechanisms within ancient and evolving orogens by which individual or linked tectonic processes may influence or predetermine the operation of other processes in space and time. Case studies cover a wide range of ancient to modern orogens: the Svecofennian of southern Finland, the Gyeonggi Massif of Korea, the Caledonides of northern Scotland, the Variscan of the East European craton, the Appalachians of the eastern United States, the European Alps and Dinarides, north Cascades of the northwestern United States, and the Himalaya. Emphasis is placed on integration between data sets developed from a wide range of analytical approaches, including: field mapping, seismic reflection profiling, strain analyses, petrology, isotopic dating, and numerical modeling-based studies of thermal evolution associated with tectonic processes such as thrust-related burial and exhumation.
This Open Access handbook published at the IAMG's 50th anniversary, presents a compilation of invited path-breaking research contributions by award-winning geoscientists who have been instrumental in shaping the IAMG. It contains 45 chapters that are categorized broadly into five parts (i) theory, (ii) general applications, (iii) exploration and resource estimation, (iv) reviews, and (v) reminiscences covering related topics like mathematical geosciences, mathematical morphology, geostatistics, fractals and multifractals, spatial statistics, multipoint geostatistics, compositional data analysis, informatics, geocomputation, numerical methods, and chaos theory in the geosciences.
