Devonian stratigraphy and paleontology of the Ram River area, AlbertaBell, Gordon Lennox January 1951 (has links)
The thesis represents a field and paleontological study of Devonian strata exposed in the Ram River Area west of Nordegg Alberta, and is intended to present information which will supplement data obtained from exploration drilling of the Great Plains basin.
Certain structural phenomena are discussed in relation to the problems of the Rocky Mountain overthrust belt. It is concluded that overfolding in many cases preceeded thrust fault development, that modification of Lawson’s equation may be necessary in the consideration of low-angle thrust faults, and that the Eastern Ranges may have suffered less displacement than those of the western Rockies.
The principles of regional and interregional correlation are discussed with a view to evaluation of the criteria and limitations of biostratigraphic correlation. Previous stratigraphic work is reviewed, and detailed descriptions of the Flume, Perdrix, and Cheviot Formations are submitted. The Perdrix Formation is recognized as being divisible into two new members, the Blackface and Whitegoat Members.
Faunal description, revision, and illustration of five species of corals and thirty species of brachiopods constitute the main part of the work. Revision shows that Leiorhynchus albertense Warren is referable to Calvinaria, and that Bellerophon neleus Hall and Whitfield is referable to Aglaeoglypta. One variety, Calvinaria albertense var. plicata is recognized as new. / Arts, Faculty of / Geography, Department of / Graduate

A population of the new species Ctenoconularia delphiensis from the New Albany Shale (Upper Devonian) at Delphi, IndianaMaroney, David G. 03 June 2011 (has links)
Ctenoconularia deiphiensis,is a new species of the Conulata based on a population of specimens from a phosphatic nodular sandstone at the base of the New Albany Shale (Upper Devonian) at Delphi,Indiana.The transverse ridges possess interridge furrows with bead-like nodes that are not structurally continuous with the ridges. The ridges are altered into four elongate pustules upon crossing the interfacial groove.Ball State UniversityMuncie, IN 47306

Stratigraphy and paleontology of the lower Devonian sequence, southwest Ellesmere Island, Canadian Arctic ArchipelagoSmith, Gary Parker. January 1984 (has links)
The Lower Devonian carbonate-clastic sequence of southwest Ellesmere Island accumulated in the Franklinian Basin at approximately 15(DEGREES)N latitude. A variety of depositional settings are represented, ranging from tidal flat to basinal environments. These environments can be recognized in Lower Devonian rocks across the Arctic Islands. / Progradation of the carbonate sequence of southwest Ellesmere Island occurred in the Early Devonian, but was periodically interrupted in the Zlichovian/Dalejan by transgressive events. Upward movement in the newly named Inglefield Uplift occurred throughout the Devonian, and shed clastic sediments westward that, in Middle to Late Devonian time, finally overwhelmed the marine carbonates and resulted in fluvial deposition on southern Ellesmere Island. / Certain formations in the Lower Devonian sequence are profusely fossiliferous, in particular the Blue Fiord Formation, which contains an abundant fauna including numerous species of coral and brachiopods. Both of these groups belong to the Old World Biogeographic Realm, and indicate a Zlichovian age for the lower Blue Fiord Formation of southern Ellesmere Island.
