Book Description

The Aylmer Lake volcanic belt, located north of the north-east end of Great Slave Lake, defines an upward-facing structural dome intruded in its core by a number of granitoid plutons and overlain by multiply folded metaturbidite units. This paper provides a summary of field observations of the belt from the 2000-01 field seasons and incorporates preliminary geochemical data from samples collected in 2000. Information is included on rock types & stratigraphic relationships in the Aylmer Lake area, on whole-rock analyses of a representative selection of rock types from the belt, and on structural & metamorphic elements of the north-east Walmsley Lake area (located just west of the belt).

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.
