SummaryMiddle Devonian to Lower Carboniferous shales and
siltstones of the Besa River Formation that are exposed in the Caribou Range of west-central Liard Basin (Fig. 1) are lithologically similar to time-equivalent shale-gas bearing rocks in the subsurface of the eastern Liard Basin and, farther east, in the Horn River Basin (Fig. 2). Complimenting a nearly identical data set obtained from the Besa River Formation in southern Liard Basin (Ferri and Reyes, 2019) and previous investigations (Ferri et al., 2011a, b), herein we present the full dataset from a continuous stratigraphic section that we measured and systematically sampled in the Caribou Range of northernmost British Columbia (Figs. 3, 4). This measured section and dataset will provide a reference for the Besa River Formation in central Liard Basin.
The UTM coordinates (NAD 83, Zone 10) for Caribou Range section are: 1) base, 367107E 6643192N; 2) 60 m stratigraphic height, 367176E 6643180N; 3) 100 m stratigraphic height, 367213E 6643151N; 4) 150 m stratigraphic height, 367266E 6643094N; 4) 185 m stratigraphic height, 367333E 6643077N; 5) 233 m stratigraphic height, 367420E 6643025N; 6) 285 mstratigraphic height (top), 367496E 6642948N.
In the accompanying files (BCGS_GF2019-11.zip) we summarize our analytical methods (Appendix 01), Rock-Eval, lithogeochemistry, stable carbon (organic) isotope geochemical, gamma ray spectrometry, thermal maturity, X-ray diffraction, and gamma ray spectrometer data (asMicrosoft Excel spreadsheets; Appendix 02), and graphic logs,lithologic descriptions, and images of representative rock types(Appendix 03).
AcknowledgementsWe thank Igor Bilot and Jeanne B. Percival, at the laboratories
of the Geological Survey of Canada in Ottawa for providing the XRD analysis. We also thank Sarah Saad and Kritsta Boyce for help processing and analyzing Rock-Eval samples. Kirk Osadetz (Geological Survey of Canada) provided background material on Rock-Eval analysis and Ray Lett (British Columbia Geological Survey) assisted with preparing samples used for lithogeochemical analysis. Part of the funding for this project originated with the Yukon Sedimentary Basin Project; Geo-mapping for Energy and Minerals (GEM) program, Geological Survey of Canada (Rock-Eval, XRD and reflective light thermal maturity analyses). Lisa Fodor and Lauren Wilson provided enthusiastic assistance in the field. We also thank Larry Lane (Geological Survey of Canada) for loaning a gamma ray spectrometer. Great Slave Helicopters Ltd. provided competent service in positioning and demobilizing the field camps.
