Cratonic-Margin and Antler-Age Foreland Basin Strata (Middle Devonian to Lower Carboniferous) of the Southern Canadian Rocky Mountains and Adjacent Plains

Microfacies development, sea-level change, and conodont stratigraphy of Famennian mid- to deep platform deposits of the Beringhauser Tunnel section (Rheinisches Schiefergebirge, Germany)

“…The ones provided by Johnson et al (1985) or Savoy and Mountjoy (1995) appear to be quite generalized when compared with detailed curves as shown by Van Tassell (1994) for the late Frasnian and Smith and Jacobi (2001) for the early Famennian. The varying quality and resolution of these curves has to be attributed to the different quality of data or the individual scope of the investigations.…”

“…This general trend reflects that of the sea-level curve provided by Johnson and Sandberg (1989) to a very high degree. In contrast, the sea-level curve of Savoy and Mountjoy (1995) promotes a continued rising sea-level until the end of the Devonian. The regional sea-level curve as reconstructed by Smith and Jacobi (2001) for the early Famennian reveals only rudimentary similarities as the sharp sea-level fall directly above the Frasnian/Famennian boundary followed by an equally sharp rise in the Upper triangularis-Zone.…”

“…In the Beringhauser Tunnel section we found lowstand deposits with packstone layers (bed 83, 85) and a subsequent minor stratigraphic condensation representing the widespread Lower marginifera sea-level rise . The lowstand in the Upper marginifera-Zone that is present in the sealevel curves of Savoy and Mountjoy (1995) and Johnson and Sandberg (1989) is represented by the extensively dolomitized upper part of bed 95 and bed 96 with its wackestone to partly grainstone lithology. The last remarkable sea-level fluctuation in the Late Devonian covered by the Beringhauser Tunnel succession is connected with the annulata-horizon (bed 119).…”

“…The sea-level curve can be compared with the few other sea-level curves that have been reconstructed for the Late Devonian (Johnson et al 1985;Johnson and Sandberg 1989;Savoy and Mountjoy 1995;Smith and Jacobi 2001;Dopieralska 2003).…”

Geochemical constraints on the origin and timing of palaeofluid flow in the Presqu’ile barrier reef, Western Canada Sedimentary Basin

“…Several major periods of tectonic compression and sedimentary loading occurred on the western margin of the Western Canada Sedimentary Basin. The earliest of these, the Antler Orogeny (Late Devonian-Early Carboniferous) occurred during shallow burial of the Presqu'ile barrier reef (Root 1993;Savoy & Mountjoy 1995). The next major tectonic event is the Columbia orogeny during Late Jurassic to Early Cretaceous time.…”
