Chemostratigraphic logging of the Lower Ordovician and Precambrian, Bells Corners Borehole Calibration Facility, Ottawa, Ontario / L.C. Olson, R.D. Knight, H.L. Crow, and H.A.J. Russell. : M183-2/8913E-PDF
"Geochemical data were collected from a 120-meter-deep borehole (BC81-2) located at the Geological Survey of Canada's Bells Corners Borehole Calibration Facility in Ottawa, Ontario. This report documents geochemical data collected for the most frequently logged of the six boreholes located at the facility. The geochemical data were collected using a portable X-ray fluorescence (pXRF) spectrometer with a subset of samples collected for modern laboratory based fusion and multi-acid methods to calibrate the pXRF data for improved accuracy. Borehole geochemistry provides a characterization of Precambrian and overlying Ordovician rocks in the Ottawa area that augments the understanding of geophysical properties obtained from the calibration borehole. The combined geochemical and geophysical datasets further define rock characteristics, formational boundaries, as well as alteration zones. The results demonstrate the usefulness of pXRF derived geochemical data and chemostratigraphy of rock cores. The chemostratigraphic data augment data collected with spectral gamma logging tools and support an enhanced interpretation of geological contacts across transitional boundaries and the nature of the matrix mineralogy"--Abstract, page 1.
