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
Dolostone mounds over 200 metres thick and over four kilometres across developed in deep water during uppermost Arctic Bay Formation shale deposition in the north-west Milne Inlet Graben on northern Baffin Island. This paper describes the geometry of hitherto unrecognized mounds that have been identified from field work in five areas: the Saint Georges Society Cliffs near Arctic Bay; beneath the Nanisivik lead-zinc deposit; Red Rock valley; Magda Lake; and Bellevue Mountain. Their lithology, lateral facies relations, and internal composition are described and an interpretation of the origin & growth of the mounds is offered. Finally, implications of mound growth & distribution for the fault-related flow of mineralizing fluids and consequent base-metal deposition are 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
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.
