3-D GEOMETRY AND KINEMATIC EVOLUTION OF THE KUPE INVERSION STRUCTURE, SOUTHERN TARANAKI BASIN, NEW ZEALAND
(2017-12)
The Southern Taranaki Basin underwent extension during the Late Cretaceous to Eocene, followed by a compression during the Oligocene to the Late Miocene, resulting in inversion of some of the pre-existing normal faults. ...
Regional stratigraphy and organic richness of the Mississippian Meramec and associated strata, Anadarko Basin, central Oklahoma
(2018-05)
The Mississippian Meramec Series and laterally equivalent units of the Caney and Sycamore formations of central and south-central Oklahoma generally consist of a succession of interbedded quartz-rich calcareous siltstones, ...
Systematics and Biostratigraphy of Dunderbergia and Related Trilobites from Cambrian (Mid-Steptoean) Strata of Nevada, Utah, Texas, and Newfoundland
(2022-05-13)
The Great Basin of Nevada and Utah has been a classic region for Cambrian geology and paleontology for some 150 years. Studies in the late 19th century were prompted by the discovery of commercial ore deposits and led to ...
ATMOSPHERIC DUST FROM THE UPPER CARBONIFEROUS COPACABANA FORMATION (BOLIVIA): A HIGH-RESOLUTION RECORD OF CLIMATE AND VOLCANISM FROM NORTHWESTERN GONDWANA
(2016-08-19)
This study documents the occurrence of atmospheric dust from Pennsylvanian carbonates of the Copacabana Formation, recovered in core (Mobil-Oxy Manuripi X-1) from the Madre de Dios basin (Bolivia), within southern mid-latitudes ...
Global Reconnaissance of Reef Spur and Groove Variability: A Systematic Geomorphic Classification.
(2021-05-16)
Spur and Groove (SaG) formations are found on the fore reef of many coral reef systems around the world. SaG features are constructed of coral buildups called “spurs”, and separated by erosive channelized features, or ...
REGIONAL STRATIGRAPHY AND DIAGENETIC CHARACTERIZATION OF THE MISSISSIPPIAN MERAMEC, OSAGE, AND SYCAMORE FORMATIONS, ANADARKO BASIN, CENTRAL OKLAHOMA
(2019-05)
The principal goals of this study were to characterize the regional stratigraphy, analyze the extent of diagenetic alteration, and determine the factors controlling reservoir quality of the Meramec, Osage, and Sycamore ...
Using 3D Seismic Attributes to Investigate Mud Losses in a Fluvial-Deltaic Sand: An Example From the Oliver Sandstone
(2017)
Drilling operations in an actively developed basin in Wyoming can experience
large quantities of mud losses in a shallow zone along the intermediate (vertical) section
of the wellbore. These losses can negatively impact ...
Photogrammetric sand grainsize analysis of a circumnavigational sampling of beaches of the big island of Hawaii: possible insight into controlling processes and provenance
(2021)
A circumnavigational photogrammetric sampling of the sands on the island of Hawai’I was done using the photogrammetry program pyDGS. The island of Hawai’i provides a perfect landscape to test the viability of pyDGS since ...
AN INTEGRATED ANALYSIS OF SEQUENCE STRATIGRAPHY, PETROLEUM GEOCHEMISTRY, AND DEVONIAN MASS EXTINCTION EVENTS IN THE WOODFORD SHALE, SOUTHERN OKLAHOMA
(2017-12-16)
Geochemical analyses of the Late Devonian-Early Mississippian Woodford Shale have revealed a more dynamic history than previously considered, reflecting discrete changes in the conditions surrounding its depositional ...
Seasonal Influences on the Molecular and Metal Binding Properties of Groundwater & Surface Water Dissolved Organic Matter (DOM) in an Alpine Watershed Located in Central Colorado
(2021-05-16)
The nature and behavior of surface water and groundwater chemistry in alpine watersheds is influenced by snowmelt-driven hydrology. This study investigated the effects of seasonal variability in groundwater and surface ...
