In Oklahoma, seismic reflection data from different areas show distinct, systematic patterns of reflectors within depth intervals dominated by the crystalline basement. It is necessary to better understand the origin and composition of these characteristic layers in the Oklahoma basement, as it will fill a major gap in the understanding of its tectonic and thermal history.

Explorer Historical Highlights

Spindletop’s glory days were gone, or so it was believed. That landmark discovery on Jan. 10, 1901 at Spindletop Hill near Beaumont, Texas had defied existing American geological thought and changed the course of history, but had faded into memory by the 1920s. But, a novel geological hypothesis would soon change all that.

Please meet Joel Núñez, one of the founders and promoters of ExoEstrato, a young association whose members are lovers of Astronomy and Planetary Sciences. ExoEstrato is supported by the Andalusian Society of Astrogeology in Granada in Andalusia, Spain. The founders explain the reasons for the ExoEstrato. 'Due to the scarcity of projects related to Planetary Geology in the spanish universities, we have decided to start this project, with the idea of disseminating, educating other people and research in the fascinating and transcendent field of Astrogeology. In spite of our short journey as an institution, we have already organized and carried out a significant number of activities, from public astronomical observations to conference cycles, including the organization of the I Course on Introduction to Astrogeology at the University of Granada, which will take place next month, or the upcoming launch of EXOJOURNAL, an astrogeological magazine. We also plan to organize this summer, with a view to develop it in the end of 2018, the I Andalusian Congress of Young Astrogeologists (CAJA, in spanish), proposing an attractive program of activities and inviting several speakers specialized in astrogeological issues.'

DL Abstract

While there are many habitats that are associated with the deposition of organic-rich marine and lacustrine source rocks, one important pathway is linked to the onset of increased basin subsidence associated with major tectonic events. A key aspect is that this subsidence is spatially variable, with the uplift of basin flanks contemporaneous with the foundering of the basin center, resulting in a steeper basin profile.

DL Abstract

Climate change is not only happening in the atmosphere but also in the anthroposphere; in some ways the former could drive or exacerbate the latter, with extreme weather excursions and extreme excursions from societal norms occurring all over the earth. Accomplishing geoscience for a common goal – whether that is for successful business activities, resource assessment for public planning, mitigating the impacts of geological hazards, or for the sheer love of furthering knowledge and understanding – can and should be done by a workforce that is equitably developed and supported. Difficulty arises when the value of institutional programs to increase equity and diversity is not realized.

President Biden has laid out a bold and ambitious goal of achieving net-zero carbon emissions in the United States by 2050.  The pathway to that target includes cutting total greenhouse gas emissions in half by 2030 and eliminating them entirely from the nation’s electricity sector by 2035. The Office of Fossil Energy and Carbon Management will play an important role in the transition to net-zero carbon emissions by reducing the environmental impacts of fossil energy production and use – and helping decarbonize other hard-to abate sectors.

VG Abstract

The carbonate sequences that were deposited in the now exhumed Tethyan Ocean influence many aspects of our lives today, either by supplying the energy that warms our homes and the fuel that powers our cars or providing the stunning landscapes for both winter and summer vacations. They also represent some of the most intensely studied rock formations in the world and have provided geoscientists with a fascinating insight into the turbulent nature of 250 Million years of Earth’s history. By combining studies from the full range of geoscience disciplines this presentation will trace the development of these carbonate sequences from their initial formation on the margins of large ancient continental masses to their present day locations in and around the Greater Mediterranean and Near East region. The first order control on growth patterns and carbonate platform development by the regional plate-tectonic setting, underlying basin architecture and fluctuations in sea level will be illustrated. The organisms that contribute to sequence development will be revealed to be treasure troves of forensic information. Finally, these rock sequences will be shown to contain all the ingredients necessary to form and retain hydrocarbons and the manner in which major post-depositional tectonic events led to the formation of some of the largest hydrocarbon accumulations in the world will be demonstrated.

DL Abstract

For well over a century there have been conflicting indications of the strength of the crust and of faults and what controls them.  Much of our ignorance comes quite naturally from the general inaccessibility of the crust to measurement--in contrast with our understanding of the atmosphere, which is much more accessible to observation as well as more rapidly changing.  Crustal strength is best understood in deforming sedimentary basins where the petroleum industry has made great contributions, particularly in deforming petroleum basins because of the practical need to predict. In this talk we take a broad look at key issues in crustal strength and deformation and what we can learn from boreholes, earthquakes, active fault systems, and toy models.

DL Abstract

Paleozoic North America has experienced multiple mountain building events, from Ordovician to Permian, on all margins of the continent. These have had a profound effect on the resulting complex basins and their associated petroleum systems. Subsequent uplift, erosion and overprinting of these ancient systems impedes the direct observation of their tectonic history. However, the basin sedimentary records are more complete, and provide additional insights into the timing and style of the mountain building events. In this study, we employ ~90 1D basin models, ~30 inverse flexural models, isopachs, and paleogeographic maps to better understand the Paleozoic history of North America.

DL Abstract

Three-dimensional (3D) seismic-reflection surveys provide one of the most important data types for understanding subsurface depositional systems. Quantitative analysis is commonly restricted to geophysical interpretation of elastic properties of rocks in the subsurface. Wide availability of 3D seismic-reflection data and integration provide opportunities for quantitative analysis of subsurface stratigraphic sequences. Here, we integrate traditional seismic-stratigraphic interpretation with quantitative geomorphologic analysis and numerical modeling to explore new insights into submarine-channel evolution.

DL Abstract

Around 170 million years ago, the Gulf of Mexico basin flooded catastrophically, and the pre-existing landscape, which had been a very rugged, arid, semi-desert world, was drowned beneath an inland sea of salt water. The drowned landscape was then buried under kilometers of salt, perfectly preserving the older topography. Now, with high-quality 3D seismic data, the salt appears as a transparent layer, and the details of the drowned world can be seen in exquisite detail, providing a unique snapshot of the world on the eve of the flooding event. We can map out hills and valleys, and a system of river gullies and a large, meandering river system. These rivers in turn fed into a deep central lake, whose surface was about 750m below global sea level. This new knowledge also reveals how the Louann Salt was deposited. In contrast to published models, the salt was deposited in a deep water, hypersaline sea. We can estimate the rate of deposition, and it was very fast; we believe that the entire thickness of several kilometers of salt was laid down in a few tens of thousands of years, making it possibly the fastest sustained deposition seen so far in the geological record.
