Book excerpt: 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).
