Sedimentology of the Cape Town boulder beds
Gravelly sediment layers in fossil beaches around the Cape Peninsula and False Bay in South Africa are assumed to be Pliocene in age and are essential for reconstructing the ancient sedimentary dynamics along the shoreline in the greater Cape Town region. The cobble- to boulder-size clasts in these …

Stratigraphy and sedimentology, Cambrian Shady Dolomite, Virginia
Cambrian Shady Dolomite facies exposed northwest and southeast of Austinville, southwestern Virginia, apparently formed in a platform-to-basin setting. Northwest of Austinville, the Shady Dolomite (600 m thick) overlies the Lower Cambrian Erwin Formation and is overlain by the Middle Cambrian Rome …

Early Mesozoic stratigraphy, sedimentology and structure of the
The Gharian area is used as a case study to examine the sedimentary succession, structural evolution and timing of sedimentary and structural events during basin development in the Early Mesozoic. These sediments (Kurrush, Al Aziza and Abu Shaybah Formations) are examined in order to provide …

The postglacial sedimentology of Devils Lake, North Dakota
<p> The present sedimentary environment of Devils Lake, a Closed brackish lake in northeastern North Dakota, was investigated, and changes in the Holocene lacustrine environment are interpreted. Sediment samples from Main Bay of Devils Lake were analyzed for their physical, chemical and mineral …

Stratigraphy and Sedimentology of the Smackover Formation, Southwest Alabama
The Smackover Formation is a highly productive producer of hydrocarbons throughout the United States Gulf Coast region. More than four million barrels of oil and five billion cubic feet of gas have been produced from the Smackover Formation in the Barnett Field in southwest Alabama. Paleohighs …

Sedimentology and diagenesis of Ediacaran phosphorites from South China
Ediacaran phosphorites provide a principal record of the paleoenvironmental and paleoecological conditions of the oceans during Earth's second major oxygenation and the evolution of complex life. Although the fidelity of this record is high, diagenesis and metamorphism frequently alter or overprint …

The sedimentology and dynamics of mega-dunes, Jamuna river, Bangladesh
This thesis quantifies the occurrence, morphology and flow dynamics of dune bcdforms in the main rivers of Bangladesh: the Jamuna, Meghna and Ganges. Field work was conducted as part of the River Survey Project (Bangladesh Flood Action Plan 24) between November 1993 and March 1996, hence …

The sedimentology of the cambrian clastic sediments of Northwest Scotland
The Cambrian clastic sediments of northwest Scotland crop-out along the line of the Moine Thrust Zone between Skye in the south and Loch Eriboll in the north and form the basal 250m of a broadly transgressive Cambro-Ordovician sequence of clastic and carbonate sediments. These sediments were …

The sedimentology of diamondiferous deflation deposits within the Sperrgebiet, Namibia
In this thesis the processes that produced diamond placer deposits within closed endoreic basins along the west coast of Namibia are addressed. These deposits, first discovered in 1908, and documented by Kaiser in 1926, occur in an area of wind deflation between latitudes 26 and 28 degrees South. …

The sedimentology and stratigraphy of Salt Creek Field, Kent County, Texas
The Horseshoe Atoll is one of the largest hydrocarbon accumulations in the Permian Basin, with a cumulative production of more than 2.7 Bbbl since 1948. This atoll is contemporaneous with the Late Paleozoic Ice Age (LPIA), perhaps the best-known Phanerozoic phase of glaciation after the …

The sedimentology, palaeoecology and stratigraphy of cretaceous rocks in N.W. Scotland
… and micropalaeontology (including palynology), sedimentology and structural data were integrated in an attempt to achieve these aims. Fieldwork was conducted in Morvern (Argy 11) and the Inner Hebridean islands' of lYlul], Eigg and Skye. In the proposed lithostratigraphy the Mo~ern Greensand …

The sedimentology and palaeoecology of the Coralline Crag (Pliocene) of Suffolk
The Coralline Crag is a Pliocene, shallow marine, bioclastic sand formation with an outcrop restricted to south-east Suffolk. Four distinct sedimentary facies have been recognised which indicate that the Coralline Crag was deposited during a single marine transgression. The stratigraphically lowest …

Sedimentology of Marine Vertebrate Burial in the Miocene Pisco Fm., Peru
<p>The Miocene Pisco Basin of Peru is known for abundant, well-preserved marine vertebrate fossils (Esperante et al. 2000). Cetacean fossils are particularly abundant—so much so that we were able to locate 10 outcrops containing specimens in cross section, which allowed us to do detailed …

Sedimentology, diagenesis and geochemistry of the Great Limestone, Carboniferous, northern England.
Yoredale type cyclothems of the Mid-Carboniferous of north east England were deposited as a result of glacio-eustatic fluctuations arising from waxing and waning of the Gondwana ice sheets present in the southern hemisphere. Rhythmic alternations of areas of maximum cyclothem thickness have been …

Sedimentology, Diagenesis and Reservoir Characteristics of Eocene Carbonates Sirt Basin, Libya
… This thesis investigates the petrography, sedimentology, diagenetic evolution and hydrocarbon potential of the Middle Eocene Gialo Formation in the subsurface of the north-central Sirt Basin based on data from core samples and well logs from five boreholes in the Assumood and Sahl …
