Geology and Hydrocarbon potential ofthe Beaufort Sea, Alaska, based on geophysical data.

Abstract/Description
Analysis of2D seismic reflection profiles, magnetic anomaly data and four well logs reveals that the continental shelf of the Beaufort Sea is in many ways, a direct geological extension ofthe prolific oil and gas province ofthe North Slope of Alaska. Stratigraphy is divided into four sequences. The organic rich shales are characterized as potential source rocks and the carbonates and marine to non marine sandstones are interpreted to be the reservoir rocks. Structural interpretation has...
Show moreAnalysis of2D seismic reflection profiles, magnetic anomaly data and four well logs reveals that the continental shelf of the Beaufort Sea is in many ways, a direct geological extension ofthe prolific oil and gas province ofthe North Slope of Alaska. Stratigraphy is divided into four sequences. The organic rich shales are characterized as potential source rocks and the carbonates and marine to non marine sandstones are interpreted to be the reservoir rocks. Structural interpretation has revealed the presence of five structures capable of trapping hydrocarbons. These structures were identified as the Barrow arch, Camden anticline, Dinkum graben, shale diapirs and normal faults. The combination of these structures and stratigraphy offer petroleum exploration companies a promising target for large accumulations of hydrocarbons.

Mollusks of the late Pleistocene oèolitic facies of the Miami Limestone in the Miami-Dade County, South Florida
Title
Mollusks of the late Pleistocene oèolitic facies of the Miami Limestone in the Miami-Dade County, South Florida.
Creator
D'Antonio, Heather M., Charles E. Schmidt College of Science, Department of Geosciences
Abstract/Description
The oèolitic limestone that makes up the bedrock of Miami-Dade and parts of Broward County, Florida, is a relatively well studied formation, with poorly studied fossil content. No published systematic record of Pleistocene fossils in the Miami Limestone is available. Besides the basic knowledge of taxonomy and biodiversity of the mollusks, comparison with extant assemblages can yield important information about the biodiversity changes in southern Florida during the past ~130,000 years....
Show moreThe oèolitic limestone that makes up the bedrock of Miami-Dade and parts of Broward County, Florida, is a relatively well studied formation, with poorly studied fossil content. No published systematic record of Pleistocene fossils in the Miami Limestone is available. Besides the basic knowledge of taxonomy and biodiversity of the mollusks, comparison with extant assemblages can yield important information about the biodiversity changes in southern Florida during the past ~130,000 years. Preliminary surveys of several localities, both previously described and new, within the Dade County yielded a record of diverse mollusks from over 28 families, 34 genera and 40 species. The preliminary findings of molluscan fossils have led to a new, unstudied and unpublished fossil locality with the second discovery of a possible Strombus costatus in the Miami Limestone. Miami Limestone fossils are being compared to recent South Florida mollusks indicating patterns of local diversification and extinction related to the minor changes in sea level and disappearance of certain habitats such as the rocky shore substrates that Cittarium pica once thrived on.

Sequence stratigraphy of the arcadia formation, Southeast Florida: an integrated approach
Title
Sequence stratigraphy of the arcadia formation, Southeast Florida: an integrated approach.
Creator
Wright, Caroline Marie, Oleinik, Anton E., Florida Atlantic University, Charles E. Schmidt College of Science, Department of Geosciences
Abstract/Description
The Arcadia Formation is a mixed carbonate-siliciclastic rock unit that existed as a shallow carbonate ramp to platform environment during the Late Oligocene to Early Miocene Epoch. It can be divided into two distinct, informal sections based on lithological properties: the upper Arcadia Formation and lower Arcadia Formation. The sections are part of a major, third-order sequence that can be further divided into four higher-frequency, lower magnitude sequences: ARS1, ARS2, ARS3, and ARS4. The...
Show moreThe Arcadia Formation is a mixed carbonate-siliciclastic rock unit that existed as a shallow carbonate ramp to platform environment during the Late Oligocene to Early Miocene Epoch. It can be divided into two distinct, informal sections based on lithological properties: the upper Arcadia Formation and lower Arcadia Formation. The sections are part of a major, third-order sequence that can be further divided into four higher-frequency, lower magnitude sequences: ARS1, ARS2, ARS3, and ARS4. The sequence boundary separating ARS2 and ARS3 represents a drastic change in the depositional regime from a high-energy, inner ramp/platform to a lower-energy, deep outer ramp environment. ARS3 represents the period of maximum flooding and constitutes a major portion of the regressive system tract (RST) of the third order depositional sequence. In certain sections, the Arcadia Formation is heavily bioturbated including ichnotaxa from the glossifungites, cruziana, and scolithos inchofacies. Thalassinoides sp. burrows of the glossifungites ichnofacies were found to be commonly associated with firmground substrates and breaks in sedimentation. The lithofacies associations were grouped into paleodepositional environments that ranged from restricted marine to deep outer ramp with lithology ranging from grainstone to wackestone to mudstone with variable amounts of siliciclastic and phosphatic constituents. Each sequence boundary extends regionally south from Broward County to southern Miami-Dade County utilizing gamma-ray geophysical signatures unique to each sequence.
