The Middle Jurassic of Western and Northern Europe: Its Subdivisions, Geochronology and Correlations
The Middle Jurassic of western and northern Europe: its subdivisions, geochronology and correlations John H. Callomon The palaeogeographic settings of Denmark and East Greenland during the Middle Jurassic are outlined. They lay in the widespread epicontinental seas that covered much of Europe in the post-Triassic transgression. It was a period of continuing eustatic sea-level rise, with only distant connections to world oceans: to the Pacific, via the narrow Viking Straits between Greenland and Norway and hence the arctic Boreal Sea to the north; and to the subtropical Tethys, via some 1200 km of shelf-seas to the south. The sedimentary history of the region was strongly influenced by two factors: tectonism and climate. Two modes of tectonic movement governed basinal evolution: crustal extension lead- ing to subsidence through rifting, such as in the Viking and Central Grabens of the North Sea; and subcrustal thermal upwelling, leading to domal uplift and the partition of marine basins through emergent physical barriers, as exemplified by the Central North Sea Dome with its associated volcanics. The climatic gradient across the 30º of temperate latitude spanned by the European seas governed biotic diversity and biogeography, finding expression in rock-forming biogenic carbonates that dominate sediments in the south and give way to largely siliciclastic sediments in the north. Geochronology of unrivalled finesse is provided by standard chronostratigraphy based on the biostratigraphy of ammonites. The Middle Jurassic saw the onset of considerable bioprovincial endemisms in these guide-fossils, making it necessary to construct parallel standard zonations for Boreal, Subboreal or NW European and Submediterranean Provinces, of which the NW European zonation provides the primary international standard. -
Petroleum Geochemistry of the Lower Cretaceous
Petroleum Geochemistry of the Lower Cretaceous Mannville and Jurassic Ellis Groups, Southern Alberta, Canada Kim Manzano-Kareah *, Shell International Exploration and Production, Houston, USA [email protected] The variation of oil quality in southern Alberta, Western Canada Sedimentary Basin, Canada is primarily due to differences in oils generated from different source rocks and biodegradation of oils in reservoirs. 280 oil samples were collected and analysed by GC and GC-MS, in order to assess the nature and extent of these petroleum systems. Oils from Lower Cretaceous Mannville and Jurassic Ellis Group reservoirs in southern Alberta, Canada (T1-40; R1-25W5) were generated from at least five different source rocks. The proven/probable source rocks include: the Devonian Duvernay Formation (Family D), the Devonian-Mississippian Exshaw Formation (Family E), a probable Paleozoic source (Family M), a probable Jurassic source (Rierdon/Fernie shales; Family F), and the Cretaceous Ostracod Zone (Family Q). Family D oils are restricted to the northernmost part of the study area (Provost field). Biodegradation and the mixing of degraded with non-degraded oils are the main factors controlling the variation in oil quality within a given family. The much improved understanding of oil families and degree of biodegradation allow for more accurate mapping of likely oil migration pathways. Known reservoir trends, subcrop edges, structure, hydrodynamics, the distribution and quality of known oil pools can all be integrated into mapping migration paths. This allows for more accurate mapping of likely oil and gas migration pathways, which can be used for prospect risking and for the ranking of exploration plays. -

The Track of the Yellowstone Hot Spot: Volcanism, Faulting, and Uplift
Geological Society of America Memoir 179 1992 Chapter 1 The track of the Yellowstone hot spot: Volcanism, faulting, and uplift Kenneth L. Pierce and Lisa A. Morgan US. Geological Survey, MS 913, Box 25046, Federal Center, Denver, Colorado 80225 ABSTRACT The track of the Yellowstone hot spot is represented by a systematic northeast-trending linear belt of silicic, caldera-forming volcanism that arrived at Yel- lowstone 2 Ma, was near American Falls, Idaho about 10 Ma, and started about 16 Ma near the Nevada-Oregon-Idaho border. From 16 to 10 Ma, particularly 16 to 14 Ma, volcanism was widely dispersed around the inferred hot-spot track in a region that now forms a moderately high volcanic plateau. From 10 to 2 Ma, silicic volcanism migrated N54OE toward Yellowstone at about 3 cm/year, leaving in its wake the topographic and structural depression of the eastern Snake River Plain (SRP). This <lo-Ma hot-spot track has the same rate and direction as that predicted by motion of the North American plate over a thermal plume fixed in the mantle. The eastern SRP is a linear, mountain- bounded, 90-km-wide trench almost entirely(?) floored by calderas that are thinly cov- ered by basalt flows. The current hot-spot position at Yellowstone is spatially related to active faulting and uplift. Basin-and-range faults in the Yellowstone-SRP region are classified into six types based on both recency of offset and height of the associated bedrock escarpment. The distribution of these fault types permits definition of three adjoining belts of faults and a pattern of waxing, culminating, and waning fault activity. -
