Stratigraphy, Sedimentology And Paleogeography Of The Lower Cretaceous (Upper Albian) Peace River, Joli Fou And Pelican Formations, Northern Alberta, Canada, Kathleen Vannelli
Stratigraphy, Sedimentology And Paleogeography Of The Lower Cretaceous (Upper Albian) Peace River, Joli Fou And Pelican Formations, Northern Alberta, Canada, Kathleen Vannelli
Electronic Thesis and Dissertation Repository
Late Albian (~ 104-101 Ma) strata in northern Alberta are assigned to the marginal-marine Paddy Member, and the marine Joli Fou, Pelican and Viking formations. Temporal relationships between these units have never been established in detail. This study shows that the marine Joli Fou mudstone forms a sheet that onlaps westward against a subaerial ridge (?forebulge); coeval fluvio-lagoonal lower Paddy strata onlap against the opposite side. The ridge crest was buried by upper Paddy strata, of Cordilleran provenance, that grade eastward into deltaic lower Pelican quartz arenites derived from the Canadian Shield. The presence of quartz arenites in the Peace …
Sedimentology Of The Mid-Carboniferous Basal Fill Of The Olta Paleovalley, Eastern Paganzo Basin, Argentina, Levi Darwin Moxness
Sedimentology Of The Mid-Carboniferous Basal Fill Of The Olta Paleovalley, Eastern Paganzo Basin, Argentina, Levi Darwin Moxness
Theses and Dissertations
As global climate transitioned from the icehouse of the Late Paleozoic Ice Age (LPIA) to greenhouse conditions of the Late Permian, glaciers vanished across Gondwana; however, not all ice centers responded synchronously. The Paganzo basin, northwestern Argentina, was geographically adjacent to significant mid-Carboniferous ice centers that disappeared notably earlier than ice over much of Gondwana. Confining the extent of glacial ice during the LPIA and resolving the timing of its disappearance is of particular interest as this dramatic climatic transition is the closest analogue in Earth history to late Cenozoic climate change, potentially aiding in anticipating the response of modern …
Pore Characterizations And Distributions Within Niagaran – Lower Salina Reef Complex Reservoirs In The Silurian Northern Niagaran Pinnacle Reef Trend, Michigan Basin, Agam Arief Suhaimi
Pore Characterizations And Distributions Within Niagaran – Lower Salina Reef Complex Reservoirs In The Silurian Northern Niagaran Pinnacle Reef Trend, Michigan Basin, Agam Arief Suhaimi
Masters Theses
The Northern Niagaran Pinnacle Reef Trend (NNPRT) has generated significant oil and gas production in Michigan. The best reservoir rock in the Reef Trend reservoirs are from porous and permeable dolomite of the Guelph Dolomite. Low-to-non reservoir limestone occurs interstratified with reservoir dolomite in many locations. This study utilizes available cores data, thin section Petrographic Image Analysis (PIA), Mercury Injection Capillary Pressure (MICP) and a newly developed Niagaran Reef depositional model (Rine, 2015) to characterize the distribution of pore geometry within each dolomitized Niagaran Reef Complex (Brown Niagaran – Lower Salina Group) reservoir facies and lithofacies. This study shows that …
Sedimentology And Stratigraphy Of The Middle Jurassic Preuss Sandstonein Northern Utah And Eastern Idaho, Preston Scott Cook
Sedimentology And Stratigraphy Of The Middle Jurassic Preuss Sandstonein Northern Utah And Eastern Idaho, Preston Scott Cook
Theses and Dissertations
The purpose of this study is to analyze the sedimentology and stratigraphy of the Middle Jurassic Preuss Sandstone and re-evaluate past sedimentological interpretations. The Preuss is located in northern Utah, western Wyoming and eastern Idaho and is stratigraphically equivalent to the Entrada Sandstone, which is Callovian in age (Dossett et al., 2014). This study is the first attempt at 1) a sequence stratigraphic framework, 2) a petroleum system analysis and 3) an extraterrestrial analog study for the Preuss. This study frames the Preuss within three broad facies groups: marine, coastal and terrestrial. The marine group includes the open marine and …
Controls On Carbonate Sedimentation And Sequence Stratigraphic Framework Of The Lower Permian (Wolfcampian) Hueco Formation (Upper-Middle And Gastropod Intervals), Robledo Shelf, Western Orogrande Basin, New Mexico, Matthew S. Harder
Open Access Theses & Dissertations
On the western margin of the Pennsylvanian/Permian Orogrande Basin, two composite measured sections in the Lower Permian upper interval of the Middle Member of the Hueco Limestone were analyzed in regards to depositional environment, facies and sequence stratigraphy. This can elucidate where potential unconventional reservoirs can be found in the Wolfcamp Shale of the Permian Basin. Based on these analyses, 12 lithofacies were identified, including 9 carbonate lithofacies: 1) fenestral dolomudstone, 2) peloidal dolomudstone, 3) ostracode foraminifera packstone, 4) foraminifera peloidal grainstone, 5) skeletal intraclast grainstone, 6) phylloid algal peloidal grainstone, 7) echinoderm phylloid algal packstone, 8) echinoderm bivalve brachiopod …
