Stratigraphy and depositional environments of the Late Jurassic Hanifa Formation along the Tuwaiq Escarpment, Saudi Arabia
(2017-06-26)
A sequence stratigraphic framework of the Late Jurassic (Oxfordian) Hanifa Formation at its exposure in Central Arabia is presented for the first time. This study offers the first high-resolution stratigraphic framework ...
Size distribution and spatial arrangement of normal faults in A-Bomb Canyon, Buckskin Mountains, Western Arizona
(2017-04-20)
The spatial arrangement of structural features, such as faults, can be randomly located, clustered together, or anti-clustered in space. The objective of this project is to understand the spatial arrangement of normal ...
A predictive exploration model for MVT Pb-Zn mineralization in Central Texas : insights from the Southeast Missouri Lead District
(2017-06-23)
Minor Pb-Zn occurrences on the flanks of the Llano Uplift in Central Texas have many geologic similarities to the world-class Mississippi Valley Type (MVT) deposits of Southeast Missouri. In both areas, metallic sulfides ...
Architecture of a mid-Cretaceous patch reef: High resolution mapping provides new insight into facies geometries and ecological relationships at Paul Spur, Bisbee, Arizona.
(2017-05-10)
Patch reef complexes are commonly found in the shelf interior of carbonate platforms. These small scattered buildups are potential hydrocarbon targets in the Maverick Basin and more broadly within Cretaceous reservoirs in ...
Isolating lithologic controls on landscape morphology in the Guadalupe Mountains, New Mexico and Texas
(2017-05-04)
In many geomorphic studies, lithologic contrasts are often acknowledged as important for landscape form, but are otherwise ignored in attempts to infer tectonic forcing or climatic control from topography. It remains ...
Carbonate platform demise and recovery at the Toarcian Oceanic Anoxic Event : high-resolution data from the Adriatic Carbonate Platform
(2017-06-28)
The sedimentological, stratigraphic, and geochemical signature of the Toarcian Oceanic Anoxic Event (OAE) on the Bahamian-style, Adriatic Carbonate Platform of Southern Europe is examined here. New stratigraphic sections ...
Evaluating the direct and indirect effects of wildfires on soil biological activity and ecosystem regeneration
(2017-06-28)
There is substantial uncertainty regarding the effects of wildfire on forest ecosystem regeneration. Some studies suggest that fires can prime ecosystems for regeneration whereas others suggest that the loss of organic ...
Fluid inclusion constraints on the hydrothermal processes responsible for Cu-Au mineralization in the Ertsberg East Skarn System, Papua, Indonesia
(2017-05-05)
The Ertsberg East Skarn System (EESS) is a 3-Gt orebody at 0.59% Cu and 0.49 ppm Au that extends from the surface at 4200m at least to 1800m elevation. Skarn-hosted Cu-Au ores are localized in Upper Cretaceous siliciclastic ...
Linking Gulf of Mexico margin submarine canyons to regional tectonics and interaction of Paleogene Lower Wilcox high frequency sequences with the Yoakum Canyon
(2017-05)
In northern Gulf of Mexico, a clustering in a 100-150 km wide area of six Late Cretaceous-Paleogene age incisions up to 1000 m deep and 100 km long suggest a structural rather than eustatic control. The incisions ...
Pre-injection reservoir characterization for CO₂ storage in the inner continental shelf of the Texas Gulf of Mexico
(2017-05)
The injection of CO₂ into the subsurface (carbon capture and storage; CCS) is the most viable approach to significantly reduce industrial emissions of greenhouse gasses to the atmosphere. The inner continental shelf of the ...
