STRATIGRAPHIC FRAMEWORK AND QUATERNARY PALEOLIMNOLOGY OF THE LAKE TURKANA RIFT, KENYA
<p>Lake sediments are some of the best archives of continental climate change, particularly in the tropics. This study is focused on three ~10m sediment cores and high-resolution seismic reflection data from Lake Turkana in northern Kenya. Lake Turkana is the world's largest desert lake and the …

Paleosol evolution in a sequence stratigraphic framework, Cretaceous Ferron Notom Delta, south central Utah, U.S.A.
Hydromorphic paleosols have been previously thought of as ever wet and poorly developed, and lacking useful paleoenviromental and paleoclimatic indicators. However, a suite of pedogenic features and geochemical attributes of hydromorphic floodplain paleosols of the youngest non-marine (100ka) …

Late Quaternary Evolution and Stratigraphic Framework Influence on Coastal Systems along the North-Central Gulf of Mexico, USA
… future barrier evolution to climate change. The stratigraphic framework and antecedent topography directly influence coastal evolution over geologic timescales. This study synthesizes ~2100km of geophysical data, 700+ sediment cores, and 63 radiocarbon dates to regionally map two sequence …

A Comparative Analysis of the Subsurface Stratigraphic Framework to the Geomorphic Evolution of the Caillou Bay Headland, South-Central Louisiana
… the distribution of subsurface lithosomes. The stratigraphic framework was developed for the headland, and lithosomes were identified to establish the distribution of different sedimentary units. The geomorphic evolution as indicated by maps was then evaluated in order to locate patterns of …

Stratigraphic framework, structural evolution and tectonic implications of the eastern Blue Ridge sequence in the central Appalachians near Warrenton, Virginia
The eastern Blue Ridge near Warrenton is composed of low grade metamorphosed and very little deformed clastic sedimentary rocks, which unconfomably overlie Middle and Late Proterozoic gneisses and granites. A thick succession of Late Proterozoic metavo1canics (Catoctin Formation) lies above the …

Reinterpreting vintage geophysical data from the Algoa and Gamtoos Basins, South Africa: an integrated sequence stratigraphic framework since the middle Mesozoic
… robust depositional models, the cornerstones of stratigraphic frameworks. Although the application of sequence stratigraphy has been a successful tool to predict the lithology of geobodies in the petroleum industry, terminology is inconsistently used by the different schools of thought to define …

Depositional History and Stratigraphic Framework of Upper Cretaceous (Campanian to Maastrichtian) Strata in the Minerva-Rockdale Oil Field of Milam County and Adjacent Counties, Texas.
… of this study is to: (1) produce a regional stratigraphic framework for the Eagle Ford though Navarro Group strata within Milam and surrounding counties, (2) document the sequence-stratigraphic framework for Campanian to Mastrichtian aged strata, (3) recreate and test the depositional shelf …

Late Tertiary Rodents from the Catamarca Province, Argentina : The Field Museum Collections
… systematically reviewed and placed within the stratigraphic framework established at the time of collection. One new genus (Proeuryzygomys) and three new species (Abracoma intermedias, Proeuryzygomys diminutiva, and Cayiodon (Lelongia) catamarcensis) are proposed. Two distinct faunas are …

A late quaternary history of Agulhas-Benguela interactions from two sediment cores on the western continental slope of South Africa
… taxon, Globorotalia inflata, provide the stratigraphic framework from which the age models were created. The results indicate that biotic responses to surface hydrological changes in the study area are complex and involve both high- and low-frequency variations.

Sequence Stratigraphy of Campanian-Maastrichtian Strata in Eastern Alabama
… 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 Chattahoochee …

Seismic sequence stratigraphy of the Lower Congo, Kwanza, and Benguela Basins, offshore Angola, Africa
… on the area's sequences. Using seismic sequence stratigraphic principles, a 2D regional seismic data set covering three basins offshore Angola, the Lower Congo, Kwanza, and Benguela Basins, was interpreted. Sequences and their unconformities were correlated within each basin as well as between …

Outcrop-derived facies model and cycle architecture of the Tansill G27-G28 high-frequency sequences, Rattlesnake Canyon, New Mexico
… high-frequency cycle (HFC)/sequence (HFS) stratigraphic framework developed and modified over decades of extensive outcrop studies (Tyrrell, 1969), making it one of the type locations to study depositinal processes of a structurally dynamic platform. This study provides the opportunity to …

Three-dimensional seismic interpretations of Miocene strata in Vermilion and South Marsh Island areas, Gulf of Mexico
… continental shelf is the most productive chronostratigraphic unit accounting for 40% of the hydrocarbons produced in the region and 40% of remaining proved reserves. The majority of active fields on the continental shelf of this region are confined to the upper Miocene and are considered mature. …
