Book Description
The Milne Inlet Graben on northern Baffin Island contains unmetamorphosed sedimentary & volcanic rocks. The middle part of the Graben includes the Society Cliffs Formation, which hosts numerous base metal showings and the Nanisivik lead-zinc deposit. Known mineralization in the Graben is predominantly limited to distinct lithofacies & stratigraphic levels of that formation. Understanding the formation's composition, origin, and lateral facies relations may be critical to determining constraints on mineralization. Existing stratigraphic nomenclature for the Formation, based on a type section in the north-west part of the Graben, does not adequately characterize the lateral variations in facies from the north-west to south-east and does not account for the Formation's evolution over time. This paper critically reviews previous research on the Formation, which has focussed on the south-east part of the Graben, and fills in the gaps in knowledge about the Formation's sedimentology & stratigraphy. It describes the distribution & lateral relations of the various lithofacies and interprets the characteristics of the basins in which they were originally deposited.

Book Description
This paper addresses previous interpretations of the origin of planar laminae and breccia networks found in carbonate rocks of the Society Cliffs Formation, which hosts numerous base metal showings and the Nanisivik zinc-lead deposit on northern Baffin Island. Field observations concerning the sedimentology of the Society Cliffs basinal laminite and the types of breccia found in laminite are presented and a new interpretation of the origin of these rocks is offered. Implications of the findings for oceanic chemistry & base metal mineralization are briefly discussed.

Book Description
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.

Book Description
"This volume focuses on the continental intraplate region of the United States and provides an update and overview of documented Quaternary faulting and paleoseismic liquefaction east of the Rocky Mountains, and of the application of these results to seismic hazard and risk assessments. Contributions include papers that describe zones of newly recognized Quaternary deformation such as the East Tennessee Seismic Zone, as well as reinterpretations of well-known areas such as the New Madrid Seismic Zone. The chapters make important contributions to the recognition of earthquake sources active during the Quaternary and assess the seismic hazards posed by these sources. This volume should interest a wide range of readers from geology, seismology, hazard assessment, and emergency management"--Provided by publisher.

Book Description
Historical geographic material, like maps, plans, and air photos, although collected and persevered by libraries, archives, and other heritage organizations, are often hidden from the general public. They can be difficult to find, access, and use. Fortunately, these caches of cartographic gems have been recognized and valued for their significant contribution to research. As a result, many of these collections have been recently digitized and made available to the public, directly and freely, online. Acting as a comprehensive guide to online historical, cartographic and other visual resources, Discovering and Using Historical Geographic Resources on the Web provides library and archival staff, and their users, with information on how to locate, interpret, understand, and use these resources. Even for experts, this book can serve as a handy reference that summarizes the different types of maps published, providing comprehensive lists of where to access them. This book is written for all library staff members who answer reference questions and provide library instruction, and for those who are interested in digitizing their own cartographic collections. It will also attract history buffs and scholars in environmental studies, history, earth sciences, anthropology, and more.

Book Description
A well-exposed section about 250 metres wide below the high water line of the Jennings River, Teslin Lake map area in northern British Columbia shows part of the Teslin Fault and provides an opportunity to constrain the fault's kinematic history by direct ground observations. This report describes preliminary structural observations of this section of the Teslin Fault, including the rock types involved, mylonitic & ultramylonitic structures, and deformation. Indications of two main episodes of shearing are discussed.

Book Description
The mission of the U.S. Geological Survey (USGS) Water Resources Discipline is to provide the information and understanding needed for wise management of the Nation's water resources. Inherent in this mission is the responsibility of collecting data that accurately describe the physical, chemical, and biological attributes of water systems. These data are used for environmental and resource assessments by the USGS, other government agencies and scientific organizations, and the general public. Reliable and quality-assured data are essential to the credibility and impartiality of the water-resources appraisals carried out by the USGS.
