... The Wellington coal bed was deposited in a rapidly subsiding and seismically active forearc basin of Late Cretaceous age, situated along the Pacific margin of North America. Coal-forming peat accumulated atop a complex of nearshore marine sand bars, into which meandering streams were incised...

... on the underlying Chase and Council Grove formations of unequivocal marine origin. For the Wellington Formation, studies favoring a continental origin are based on selected paleontological aspects (e.g., insect beds) constrained to certain horizons. Few studies have focused on the siliciclastic strata, which...

... Feather, which precludes the formation of the Sirius diamictite by either a local valley glacier or a cirque glacier. We infer that this fragment of ancient valley floor has survived because of its position between (and at a large angle to) major paleo–outlet glaciers whose beds have long since been...

... with massive sandstone tongues, and some coal beds. The platform facies is markedly cyclical, consisting of repeated sandstone, coal, limestone, shale sequences. The Arkoma geosyncline ceased to exist at the close of Desmoinesian time and upper Pennsylvanian rocks are no thicker in the Arkoma basin area than...

...C.B. Atkins; P.J. Barrett; S.R. Hicock Abstract Here we report previously undescribed features of erosion and deposition by a cold (polar) glacier. A recent study challenged the assumption that cold glaciers neither slide nor abrade their beds, but no geological evidence was offered. The features...

...Gareth R. L. Chalmers; Ron Boyd; Claus F. K. Diessel Abstract Sequence stratigraphy and coal cycles based on accommodation trends were investigated in the coal-bearing Lower Cretaceous Mannville Group in the Lloydminster heavy oil field, eastern Alberta. The study area is in a low accommodation...

... of varicoloured, silty claystones, interbedded with limestone stringers or sandstone beds and traces to thin-beds of coal. Where penetrated, the Upper Jurassic ranges in thickness from 366 to 506 m, but it is absent in 18/20-1 through erosion at the Base Cretaceous Unconformity. Fig. 5. Stratigraphic...
