This book was released on 2004 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electrical resistivity measurements previously made on graphitic shale samples from the Astarte River Formation on Baffin Island indicate that they display weak to strong anisotropic characteristics, with low and high resistivities in the directions parallel & perpendicular to foliation respectively. The purpose of the study described in this paper is to determine the electrical conductivity mechanisms that resulted in those characteristics. Study methods included electrical resistivity and porosity measurements, graphite thin-section analysis, and scanning electron microscopy. Resistivity-related factors examined in the study include pore-fluid connectivity, the presence of graphite, and the insulating quality of quartz grain layers.

This book was released on 2004 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: The purpose of this paper is to document results of pore size analyses 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 pore size distribution analyses of four black graphitic shale samples subjected to mercury injection porosimetry measurements. These measurements are essential for the electrical mechanism analysis of these samples. Porosity values are compared to those typical of mudstone or crystalline rocks.

This book was released on 2004 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this paper is to document results of the determination of electrical resistivity characteristics of schist samples from the Gold Lake area of the Yellowknife mining district, Northwest Territories, for use in interpreting ground electromagnetic surveys that have been conducted in that region. Results are presented from investigations of electrical conductivity mechanisms determined for five sub-samples taken from two mineralized schist samples selected to characterize the resistivity of the alteration zone and to determine the effect of cross-cutting veins & of fine-grained sulphide minerals oriented parallel to foliation. Resistivity-related factors examined in the study include sulphide grain connectivity, the insulating quality of quartz & calcite grain layers, and pore-fluid connectivity.
