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

Formation resistivity factor and pore-surface resistivity values were determined for three mineralized & nonmineralized rock samples from the Giant mine & Con mine areas of the Yellowknife mining district. The purpose was to provide basic information required to understand the electrical conductivity mechanisms of these rocks and to aid interpretation of geophysical surveys conducted in these areas. This paper describes the methods & processes used to obtain the formation factor data & to document the results for use in future studies.

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 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.
