“…In the study area, the dominant thrust fault is the Brazeau thrust, which has carried Cambrian rocks over Mesozoic rocks with a displacement of at least 20 km (12 mi) at the Paleozoic level (Langenberg et al, 2002) ( Figure 3). The hanging wall of the Brazeau thrust fault contains an almost complete Paleozoic section about 1800 m (5905 ft) thick, and the underthrust Mesozoic section is interpreted to extend more than 10 km (6 mi) to the west in the footwall.…”

He received both his B.A. degree in natural sciences (1986) and his Ph.D. in earth sciences (1991) from Cambridge University. Following 2 years of postdoctoral research at the University of British Columbia, he was a research professor at the University of Washington in Seattle from 1993 to 2000. Since 2000, he has been on the faculty of the University of Alberta, and his research is focused on electromagnetic exploration methods. This includes applications in continental tectonics, with recent studies of the San Andreas fault, the Tibetan Plateau, and the Canadian Cordillera. He has also applied electromagnetic methods to environmental and exploration studies.

The distribution of methane content in the coalbed is complex in the Qinshan Syncline of western Guizhou Province. Analyses of factors controlling on the distribution of gas content are made in this paper. Coal ranks and geo-structure in the region showed strong controls on the gas distribution. Coals with higher degree of metamorphism or located in syncline most likely have higher gas content. With the concept of coalbed methane content unite thickness (CBMCUT), those factors such as coal seam buried depth and coal structure present positive relations with gas content. Results indicated that the variation of CBMCUT is not fixed in different research areas or in different coal structures. Namely, the variation follows "v-shaped" correlation with the increasing coal buried depth in the region of Qinshan Syncline. However, the trend is smooth for the coals in the Panzhuang mining area. Usually, the critical value for primary-texture coal and mylonitized is different based on the analysis of the relationship between coal structure and CBMCUT in those two areas described above. The value is commonly higher in mylonitized coal and lower in those mainly primary-texture and fragmented coals.

“…Furthermore, a dense set of maturity ranks from literature is included: from Hacquebard and Donaldson [1974] with samples from the foothills and Crowsnest Pass area and from Pearson and Grieve [1985] from across the Fernie Basin. Furthermore, maturity ranks from several wells and surface samples for the foreland and foothills areas have been taken from Geological Survey of Canada open file reports [Snowdon, 1997; and several other wells (i.e., 7-34-3-1W5 and 6-14-8-5W5) and a few surface samples from a variety of reports [Cooley et al, 2006;Hannigan et al, 1993;Langenberg et al, 2002]. The legend gives a correlation table between Ro and Tmax, petroleum systems, and a color table utilized for our OMR categorization.…”

[1] The southern Canadian foreland fold-and-thrust belt (FFTB) (SW Alberta -SE British Columbia) records the interplay between foreland basin evolution with the deforming wedge and thus controls the regionalscale overburden and exhumation history. Overburden estimates are typically based on the assumption that peak burials were reached by sedimentary burial prior to the emplacement of thrust sheets. This study combines organic maturity ranks from a newly compiled catalog with forward thermokinematic modeling to examine this assumption. The organic maturity rank trends correlate not only to sedimentary but also to tectonic burial histories. The forward thermokinematic modeling builds on this combined burial history scenario and shows how required peak burial and temperatures can be achieved with reduced sedimentary overburden when combined with tectonic loading. We thus consider that the overburden was reached during instead of prior to the contraction of the FFTB as result of an integrated sedimentary and tectonic burial history. Thermokinematic modeling also suggests that firstorder steady state temperature conditions prevail during the development of the FFTB. Differently from earlier findings that considered a drop in paleotemperature gradient during the belts growth, steady state conditions reduce the amount of regional overburden required and, consequently, of eroded sediments. Besides tracing the regional evolution, organic maturity ranks are also affected by more local phenomena such as thrust-scale denudation patterns and fluid flow. Citation: Hardebol, N. J., J. P.
