Abstract:

The Lower Jurassic stratigraphy of seven contrasting areas in western Europe is compared in order to seek evidence for a pan-Western European stratigraphic forcing mechanism. Sequencestratigraphic models are discussed and emphasis is placed upon the differing response of sedimentary systems in "accommodation space-dominated" and "supply-dominated" settings. Spectral gamma-ray data from clastic successions in the Wessex and Cleveland basins (England) are used to elucidate vertical trends. A proximal-distal model for control of Th/K ratios is advanced.

Abstract:

Quad 9 of the U.K.C.S., North Sea is located 215 miles NE of Aberdeen. It contains four producing fields with over 400 mmbbls of oil and NGL's and 5.1 TCF of gas initially in place. The major reservoir unit is the Middle Jurassic (Bajocian to Bathonian) Beryl Formation, a marginal to shallow marine deposit which varies in thickness from 150' to 1100' across the studied area. It was deposited within the Beryl Embayment, a transfer zone between two actively extending basin bounding faults of the South Viking Graben, prior to the onset of the major rifting phase during the Callovian to Ryazanian.

Abstract:

Terrestrial carbon-isotope stratigraphy has proven a promising tool for stratigraphic correlation between the different exchangeable carbon-isotope reservoirs, as well as a powerful approach to reconstructing the evolution of δ13C of atmospheric CO2, which is closely associated with the evolution of palaeoenvironment and palaeoclimate. However, the limited understanding of pitfalls in specific application potentially restricts the method’s utility for stratigraphic correlation and palaeoenvironmental reconstruction.

Abstract:

The late Middle Jurassic (Callovian) Entrada Sandstone has been divided into two general facies associations consisting primarily of eolian sandstones in eastern Utah and "muddy" redbeds in central Utah. Sedimentary structures within the redbed portion are explained by the interfingering of inland sabkha, alluvial, and eolian depositional systems. A complete succession from the most basinward facies to the most terrestrial facies in the Entrada Sandstone consists of inland sabkha facies overlain by either alluvial or eolian facies. Where both alluvial and eolian facies interfinger, alluvial f

However, the reliability of palynofacies analysis as a tool for environmental reconstruction has been questioned recently. This uncertainty is due a number of factors, including the lack of standardisation in the processing and counting of organic matter, subjective and vague terminology used to classify organic matter, and

<p> Upheaval Dome is a structurally deformed topographic depression located in Canyonlands National Park, southeast Utah. Multiple hypotheses for its origin have been proposed by various scientists over many years of research. The two remaining viable hypotheses are at opposite ends of the geologic spectrum, one proposing long-term deformation of the structure, while the other proposes a catastrophic meteorite impact. (1) The seminal paper by Jackson et al. (1998) suggests that Upheaval Dome was created due to the growth and subsequent pinch-off of a salt diapir sourced from the Pennsylvanian

Abstract:

The Middle-Upper Jurassic sedimentary rocks (i.e., the Entrada Sandstone, Wanakah Formation, and Morrison Formation) in western Colorado were mostly deposited in the Paradox Basin and form part of the modern-day Colorado Plateau in the Cordilleran foreland region. These rocks were deposited in the Mesozoic during periods of active tectonic processes in western and eastern Laurentia due to the Cordilleran magmatism and continued rifting of Pangaea, respectively. The Middle-Late Jurassic sedimentary record in the Paradox Basin shows rapid transition in depositional environments, pulses in sedime

Abstract:

Biostratigraphic analysis of the lower part (Oxfordian-Kimmeridgian) of the Upper Jurassic Humber Group in the Outer Moray Firth of the North Sea and coeval onshore Scottish sections has resolved a long-standing controversy regarding the stratigraphic range of key dinoflagellate cyst (‘dinocyst’) taxa. The biostratigraphic ranges of these key species can now be shown to be comparable for Scotland, the North Sea and the classic Upper Jurassic English sections, indicating that the former North Sea Dome did not represent a barrier to faunal migration in Kimmeridgian times.

Abstract:

La zone étudiée est située dans le nord de l’Irak dans la Région Autonome du Kurdistan. Cette région correspond géographiquement à la partie nord-ouest de la chaîne du Zagros. La chaîne du Zagros est une chaîne plissée de couverture longue d’environ 1800 km. Elle résulte du plissement de la couverture sédimentaire de la marge et de la plate-forme de la plaque arabe pendant la collision cénozoïque entre la plaque arabe et l’Eurasie. Ce travail s’appuie sur une étude tectono-stratigraphique des série jurassique à cénozoïque du Kurdistan. La période antérieure à la collision a principalement été

Abstract:

"Belt Island", an influential positive structure during the Jurassic, is widely represented in the geologic literature from 1948 to present. Introduced as primarily a stratigraphic anomaly in isopach maps of the Ellis Group, the inherent spatial and temporal context was loosely constrained. In subsequent literature, it is widely referenced in a structural context, though support is lacking for originating paleotectonics and stratigraphic data is minimal. Do the stratigraphy, sedimentology, and regional tectonics support the theory of a paleogeographic/paleotectonic high in north-cent
