Sequence Stratigraphy of Campanian-Maastrichtian Strata in Eastern Alabama
… oil rich areas down dip in the Gulf of Mexico. A sequence stratigraphic framework using the T-R cycle methodology of Embry (2002) has been established by integrating surface and subsurface lithologic data with biostratigraphic zonations into Petra ®. High sedimentation from the ancestral …

High-resolution sequence stratigraphy and diagenesis of mixed carbonate/siliciclastic successions.
… nearshore successions can be explained within a sequence stratigraphic concept; to assess whether the identification and analysis of these features can be used to aid in making sequence stratigraphic interpretations; and to evaluate whether sequence stratigraphy can be used to predict the …

Sequence Stratigraphy and Resource Assessment of Aux Vases Sandstone in Illinois
Sequence stratigraphy is a useful tool for reducing cost of exploiting Aux Vases Sandstone resources. Sequence stratigraphy can be used in delineating areas best for hydrocarbons and water recovery, highlighting potential problems in quarrying operations, outlining regions where calcareous …

High resolution sequence stratigraphy of late Mississippian carbonates in the Appalachian Basin
… transgression that formed the Mississippian supersequence. The St. Louis- to Glen Dean interval consists of up to twelve fourth-order depositional sequences (300 to 400 k.y. average duration). The sequences (a few meters to over a hundred meters thick) consist of eolianites, lagoonal carbonate …

Geology of Mangapanian (late pliocene) strata, Wanganui Basin: lithostratigraphy, paleontology and sequence stratigraphy
… siltstone and sandstone units comprise a 41 k.y. sequence. Similarities in the character of these three sequences provide constraints upon which a model cyclothem is based. Comparison of other 41 k.y. sequences within the Mangapanian succession with the model cyclothem reveal subtle patterns in …

Micropalaeontology, Palaeoenvironments and Sequence Stratigraphy of the Sulaiy Formation of Eastern Saudi Arabia
… the understanding of the Sulaiy Formation sequence stratigraphical correlation, regional lateral variations and palaeoenvironmental investigation. Lithological and semi-quantitative micropalaeontological analysis of 1277 thin sections taken from core samples from nine cored wells providing …

Seismic sequence stratigraphy of the Lower Congo, Kwanza, and Benguela Basins, offshore Angola, Africa
Sequences are recognized throughout the geologic record. The Angolan margin provides an excellent opportunity to examine the factors that control the deposition and preservation of sediments in sequences, as well as the factors that create the erosion or non-deposition along sequence boundaries. …

PALAEOECOLOGY, PALAEOENVIRONMENTAL ANALYSIS AND THEIR APPLICATION TO SEQUENCE STRATIGRAPHY: LOWER CRETACEOUS, LUSITANIAN BASIN, PORTUGAL
… cycles and the recognition of ancient cycles and sequences. Although many recent studies have attempted to combine palaeoecology and sequence stratigraphy, the sequence stratigraphic model is commonly used to provide a temporally constrained framework for the evaluation of ecological and …

FORAMINIFERAL DISTRIBUTION AND SEQUENCE STRATIGRAPHY OF OXFORDIAN SUCCESSIONS IN THE WESSEX/ANGLO-PARIS BASIN
The use of micropalaeontology within a sequence stratigraphic context is rapidly emerging as a valuable tool for the recognition of ancient cycles and sequences. This study shows how micropalaeontology can be used to develop insights into sequence stratigraphic interpretations. A micropalaeontology …

Sequence Stratigraphy of Middle-Mississippian Carbonates of the Southern Appalachians: Tuscumbia Limestone, Tuscumbia, AL
<p>This field-based research develops a sequence stratigraphic framework and detailed facies analysis which is used as a basis for understanding depositional histories of low-latitude, shallow-water, Mississippian carbonate deposits (Fort Payne Chert and Tuscumbia Limestone) in northwestern …

Sequence stratigraphy and reservoir characterization of the Glauconitic sandstone, Mannville group, southern Alberta Basin
Includes bibliographical references (pages 109-117).

High-Resolution Sequence Stratigraphy of Late Mississippian (Chesterian) Mixed Carbonates and Siliciclastics, Illinois Basin
… mixed carbonate-siliciclastic sequences were deposited in the tectonically-active, tide-dominated Illinois basin during the Late Mississippian greenhouse to icehouse transition. Detailed, lithologic cross-sections were constructed through the Chesterian Ste. Genevieve through …

Depositional Environments and Sequence Stratigraphy of Upper Mississippian Strata in the Central Appalachian Basin
… interval. Seventeen transgressive-regressive sequences comprise the study interval in the basin depocenter. Five sequence types defined by the degree of incision and the thickness/ character of dominant facies include: 1) major incised valley-fill to coastal plain, 2) major incised valley-fill …

Sedimentology, ichnology and sequence stratigraphy of the Lower Cambrian Gog Group, southern Rocky Mountains, Canada
… transgression. This study focuses on the stratigraphy, sedimentology and ichnology in the Bow Valley region, specifically the sector from Mount Assiniboine northwest to the North Saskatchewan River. The objectives of this project were several-fold: (1) revise the existing stratigraphic …

Sequence stratigraphy and structure of the tertiary limestones in the Gulf of Papua,Papua New Guinea
A sequence stratigraphic study was conducted on the Mendi and Darai Limestone Megasequences in the foreland area of the Papuan Basin in Papuan New Guinea. It involved the integrated use of seismic, wireline log, well core and cuttings, strontium isotope age and biostratigraphic data. This study …

Cyclostratigraphy and sequence stratigraphy of the Solent Group (Eocene-Oligocene) of the Isle of Wight, UK
… to demonstrate the presence of seven conspicuous sequences. For the first time, these are tied to an accurate magnetostratigraphic framework. Investigation of the cyclic signal in clay mineralogical data reveals that sea level was controlled by the ~400ka cycle of astronomical (Milankovitch) …
