Book Synopsis Rift Basin-fill Architecture of Fluvial-lacustrine Lower Permian Lucaogou and Hongyanchi Low-order Cycles, Bogda Mountains, NW China by : Brad Marquis Jeffrey

This book was released on 2012 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rapid lateral facies and thickness changes, autogenic processes, and irregular topography of nonmarine rift basins challenge the application of traditional marine sequence stratigraphic techniques. Stratigraphic architecture may be reconstructed with a process-based approach, using interpreted climatic and tectonic controlling processes on sedimentation in addition to observable attributes to correlate sedimentary cycles. This hypothesis is tested for Lower Permian Lucaogou and Hongyanchi low-order cycles (LCs) in the Tarlong-Taodonggou half graben, using outcrop and petrographic data. The exposed graben fill covers 88 km2. Depositional environments and controlling sedimentary processes were interpreted on five measured sections, 0.2 -- 5 km apart. Microscopic and X-ray Diffraction data on grain composition and texture substantiate field interpretations and minimize stratigraphic miscorrelation. Humid to arid climatic conditions were interpreted using climate-sensitive lithologies, such as paleosols; tectonic movements were interpreted in terms of source area uplift, basin subsidence, and spill-point movement. The Lucaogou-Hongyanchi LC boundary (LCB) separates uppermost Lucaogou fluctuating profundal lacustrine high-order cycles (HC) from basal Hongyanchi fluvial-deltaic HCs, indicating drastic environmental change. The LCB is an erosional unconformity across which the type and magnitude of facies shifts varies greatly across the half-graben. A process based sequence-stratigraphic reconstruction across the LCB enables reconstruction of the three dimensional distribution of lithofacies across the boundary, and provides insights to the potential causes for drastic environmental change. A better understanding of the nature and origins of the LCB may be applicable to other similar nonmarine rift basins.

Available in PDF, EPUB and Kindle. Book excerpt: The well-known clinoformal geometry of a basin-fill, with an alluvial to shelf segment, deep-water slope segment, and a basin floor segment, arises from the development of a wedge-shaped body of sediment at the basin-margin that has been termed a basin-margin wedge or a shelf-slope sedimentary prism. The basin-margin wedge characteristically has atopset-foreset clinoformal geometry, with its topset dominated by alluvial, coastal and shelfal processes, while its foreset is dominated by turbidite sedimentation. Tectonic configuration of the basin, sediment supply, and relative sea level variation are some of the major factors that control the development and growth of the basin-margin wedge. This dissertation documents two distinct stages of development of the basin-margin wedge at an Eocene active margin, and relates the observed variability in the nature of the shelf-margin, deep-water slope, and basin-floor deposits with these stages. The Tyee Basin in western Oregon was a forearc basin that was filled during late early Eocene and Middle Eocene under greenhouse climatic condition. The sedimentary succession of the Tyee Basin include continental, shallow-marine and deep-water sandstones that are well exposed in Coast Range area of Oregon. The variability observed within the thick and laterally extensive turbidite sandstones of the Tyee Basin led to contrasting depositional models for the Tyee basin in the past. Notably, the submarine ramp model, which provides an alternative model for deepwater coarse clastic deposition, was proposed based on the sedimentary succession of the Tyee Basin. Reconstruction of the clinoformal geometry of the Tyee Basin succession from detailed field data (more than 1000 outcrop locations) and subsurface data reveals two distinct stages of development of this active basin-margin. Each stage has a distinct style of clinoform development and a distinct character of associated sandy deepwater deposits. At the initial stage the basin-margin clinoforms appear to be small ( 250m clinoform height) and strongly progradational, with clinoform topset dominated by the feeder fluvial deposits. At this stage, sandy unconfined (not channelized) turbidite deposits accumulated on the Tyee deepwater slope and extended to the Tyee basin-floor. Large scale sediment conduits on the deepwater slope, in the form of slope channels or canyons, are notably absent in this stage. The second stage is characterized by larger clinoform height ( 500m), higher degree of topset aggradation with repeated fluvio-deltaic cycles on the shelf, and spectacular, sand-rich, well-organized turbidite channels and canyons on the slope. The slope channels active at this stage supplied coarse sediments to the basin-floor to form unusually thick basin-floor fans. The first infill stage represents the embryonic development of a basin-margin wedge on the Tyee continental margin, and could have some similarity with the previously mentioned submarine ramp model. But this was followed by a much longer period of basin-filling when repeated fluvial and shallow-marine cycles formed on the shelf and well-organized turbidite channels were active on the slope supplying sands to the Tyee Basin floor fans. It was concluded that the two stages of development of the basin-margin wedge in the Tyee Basin is controlled largely by the configuration of the basin, that is a result of the prominent topographic/bathymetric features in oceanic basement underlying the sedimentary succession of the Tyee Basin. Tectonically active hinterland and greenhouse climate may have contributed to a relatively high sediment supply to the basin. The relatively small-amplitude sea level variations expected under greenhouse climatic condition of the Early to Middle Eocene are likely to have relatively minor effect on the architecture of the basin-fill. The present work on Tyee Basin builds on earlier research on this basin, but now establishes a ground trothed clinoformal growth model, revises the existing interpretation of sediment transport direction during a major part of the basin-filling history, and demonstrates a two-stage evolution of margin accretion. The observations from the active Tyee Basin was compared and contrasted with a latest Pleistocene sediment wedge on the New Jersey outer shelf. This sediment wedge, developed under icehouse climatic condition, and on a passive margin, was studied using high resolution seismic data (CHIRP). In contrast to the sedimentary succession of the Tyee Basin, the depositional architecture of the sediment wedge on outer New Jersey shelf, which was interpreted as a set of falling stage deltaic clinothems, appears to be strongly controlled by eustatic sea level variation of latest Pleistocene.

Book Synopsis Evaluating Controls on Fluvial Architecture, Lance Formation, Bighorn Basin, Wyoming by : Jennifer L. McHarge

This book was released on 2008 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: Deconstructing the complex architecture of ancient alluvial deposits requires an understanding of the processes that affect fluvial systems. Allogenic (extrabasinal) processes (e.g. base-level, tectonics, and climate) are considered a primary control on the stratigraphic distribution of channel bodies in the rock record. However, recent studies have indicated that autogenic (intrabasinal) stratigraphic organization may occur within fluvial systems on basin-filling time scales (10 5 -10 6 years). Zones rich in channel-belt deposits seen in alluvial basin fills can be generated by several different mechanisms including processes that are initially degradational (e.g. incised-valleys produced by base-level changes) and solely aggradational processes (e.g. tectonic damming, climate change, and long-time scale organization of river avulsion, called avulsion clustering). The fluvial-dominated Lance Formation (Maastrichtian; Bighorn Basin, WY) is characterized by large, sandstone channel belt deposits separated by intervals of mudstone floodplain deposits. Sand-dominated intervals in the basin have been tentatively interpreted by Webb (2001) as incised-valley fills, where valley formation occurs during relative sea-level lowstands and valley infilling takes place during subsequent relative sea level rise. The purpose of this study is to establish and evaluate criteria to distinguish between four models that could explain high concentrations of channel-belt sand bodies in fluvial successions. The Lance Formation in the southern Bighorn Basin is evaluated using field data and aerial photographs in an effort to determine whether these sand-dominated intervals are truly incised-valley fills resulting from relative base-level changes, or if they were generated by other processes. Sections of the Lance Formation were measured at five localities on the western and southern margins of the Bighorn Basin. Sand body geometries in both areas show average paleoflow depths on the scale of ~3 meters. Two types of sand body distributions are seen: multistory sand sheet-like deposits and lenticular isolated sand bodies. Multistory sand bodies consist of 2-4 stories and each story is about one paleoflow depth thick. Aspect ratio of the largest sand bodies are about 50:1. Results of this study indicate that sand-dominated intervals in the Lance Formation are aggradational in origin, rather than erosional. Additionally, there is no strong stratigraphic evidence for either tectonic damming or climate as controlling distribution of sand bodies. Rather, the alluvial architecture observed in the Lance Formation could have formed in the same way as the Ferris Formation (Maastrichtian/Paleogene, Hanna Basin, WY). Closely-spaced sand bodies in the Ferris Formation are interpreted as channel-belt deposits of solely aggradational origin, and have been compared to autogenic avulsion stratigraphy produced in experimental basins. Heterogeneities in sand body distribution identified in the Lance Formation Bighorn Basin may be comparable to that observed in the Ferris Formation, although at a larger spatial scale. The implications of this study show that groupings of sand bodies in fluvial successions do not necessarily indicate the influence of allogenic processes.

Book Synopsis Vertebrate Paleontology in Utah by : David D. Gillette
Download or read book Vertebrate Paleontology in Utah written by David D. Gillette and published by Utah Geological Survey. This book was released on 1999 with total page 568 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 52 papers in this vary in content from summaries or state-of-knowledge treatments, to detailed contributions that describe new species. Although the distinction is subtle, the title (Vertebrate Paleontology in Utah) indicates the science of paleontology in the state of Utah, rather than the even more ambitious intent if it were given the title “Vertebrate Paleontology of Utah” which would promise an encyclopedic treatment of the subject. The science of vertebrate paleontology in Utah is robust and intense. It has grown prodigiously in the past decade, and promises to continue to grow indefinitely. This research benefits everyone in the state, through Utah’s muse ums and educational institutions, which are the direct beneficiaries.
