Book excerpt: Regional depositional systems analyses combining surface and subsurface geological and geophysical data provide the framework for a sequence stratigraphic study of the Lower Oligocene Vicksburg Formation of the Gulf Coastal Plain. The results describe the eustatic history of the Vicksburg stratigraphic unit. The two primary Texas depocenters, the Houston embayment and the Rio Grande embayment, were separated by a deep-rooted structural nose: the San Marcos arch. A barrier / strandplain intervened between the Louisiana deltaic depocenter and the Houston embayment. Within the embayments, deltaic complexes merged along strike with barrier / strandplains. Contemporaneous growth faulting controlled deltaic depositional patterns in the Rio Grande embayment and, to a lesser degree, in the Houston embayment. Smaller wave-dominated delta complexes interspersed with barrier / strandplains extended across the San Marcos arch. Updip of the paralic depocenters, fluvial systems traversed coastal plain units. Seaward of the paralic systems, sand and mud deposits prograded across and built up over the relict Jackson shelf and shelf margin. The contact between the Vicksburg Formation and the underlying Jackson Group marks the position of the Eocene - Oligocene boundary within the Gulf Coastal Plain section. On regional dip-oriented well-log cross sections there is a distinct, abrupt, seaward shift in the paralic facies at the Jackson - Vicksburg boundary; this contact corresponds to an Exxon-model Type 1 unconformity. The unconformity is related to the development of an Antarctic ice sheet in the earliest Oligocene. During middle Vicksburg time, a minor transgression (genetic stratigraphic sequence boundary) flooded the coastal plain. Overlying the progradational Vicksburg Formation, the lower Frio Formation accumulated in an aggradational mode; this switch of depositional modes corresponds to an Exxon-model Type 2 sequence boundary. Construction of genetic stratigraphic sequence diagrams and comparison to Exxon's coastal onlap curves across different areas of the Oligocene coast show that the effects of local depocenters (sediment influx) may mask eustatic effects. Only truly regional events, such as the middle Vicksburg transgression and the basal Vicksburg seaward shift in coastal position, correlate across the coastal plain and may result from a eustatic change.

Available in PDF, EPUB and Kindle. Book excerpt: Eocene elastic sediments of the central and northern North Sea comprise five stratigraphic sequences. Oldest is the sand-dominated, basin-centered Frigg sequence, which includes submarine fan and apron deposits on the Beryl Terrace and in the Central and Viking Grabens. Middle Eocene Lower and Upper Hordaland sequences are mixed mud and sand units which prograded from the East Shetland Platform and Moray Firth and include discrete slope aprons and basin-center fans. The thin, regressive sand-prone Belton sequence marks the top of the Eocene in most of the basin, except on the eastern margin of the Shetland Platform, where the foreshelf pro grading prism of Thet sequence sandstones and siltstones was deposited. Foraminiferal biofacies analysis of a well on the Beryl Terrace indicates that four or the five sequence boundaries coincide with significant changes in the benthic and planktic foraminiferal assemblages. Cluster analysis confirms the distinct biofacies characterizing each sequence, an impoverished coarsely agglutinated fauna with radiolaria in the Frigg sequence, normal abundances or coarsely agglutinated forms in the Hordaland units, and "Velasco"-type deep-water calcareous benthics in the Upper Eocene, including planktic foraminifera in the Belton. Paleoenvironmental analysis or these biofacies shows an overall Eocene shallowing from lower slope to outer shelf. Subsidence analysis using the derived water depths indicates that the Eocene was part or a major phase of subsidence which began in the Late Paleocene and abated by Oligocene time. Overall, the Eocene constitutes a tectonosequence, or stratigraphic sequence attributable to tectonic influences. Eocene circum-North Sea tectonics include Atlantic domain seafloor-spreading to the north and west and the encroaching Alpine compression from the south. The base Eocene, top Frigg, and top Eocene all correlate with changes in seafloor spreading thought to have contributed, through intraplate stresses, to the stress regime and differential topography of the source area and basin. Latest Eocene eustatic lowering, climatic cooling, and Arctic water circulation are thought to have influenced the Thet sequence.
