Drilling the Marathousa palaeo‐lake in Greece (Peloponnese): inferring the environmental context of a Middle Pleistocene archaeological site

open access: yesBoreas, EarlyView.
The Megalopolis Basin is located in the central Peloponnese (Greece), a region that is situated along one of the primary Pleistocene biogeographical corridors for intracontinental hominin migration. The basin comprises several hundred metres of Plio‐Pleistocene sediments alternating between clastics and lignites.

Analysis of Early Permian Fauna of the Upland Region of Bally Mountain From Collected Blocks

open access: yes, 2023
Bally Mountain and her sister site, Richards Spur, both located in Oklahoma, have long been sites for prominent fossil findings of Early Permian upland terrestrial fauna, owing to their unique methods of preservation.

Molecular dynamics simulations and fluorescence spectroscopy suggest reduced tryptophan‐to‐heme energy transfer facilitates lignin degradation in ClassII peroxidases

open access: yesThe FEBS Journal, EarlyView.
In lignin peroxidase and versatile peroxidase, low FRET from buried Trp to heme promotes long‐range electron transfer (LRET) from substrate to heme. This efficient electron flow is facilitated by reduced FRET competition. This mechanism likely evolved to enable the effective degradation of bulky, high‐redox‐potential lignin that cannot reach the enzyme'

Seismic attribute and well-log analysis for channel characterization in the upper San Andres and Grayburg formations of the Midland Basin, Texas

open access: yesEnergy Geoscience
The Permian Basin is one of the most prolific, and currently one of the most active, oil and gas basins in the USA. The Lower Permian strata in the Permian Basin have produced more than 14 billion barrels of oil (BBO), making it the largest volume of ...

The Unexpected Discovery of Paleocene? Coals in Outcrops Thought to Be Cambrian, Al Huqf, Oman

open access: yesJournal of Petroleum Geology, EarlyView.
ABSTRACT Two brown organic deposits were encountered whilst investigating kaolinitic claystones thought to occur at the base of a Cambrian formation at outcrop. The age of these organic deposits is probably Paleocene from palynology. Organic petrography shows that they are subbituminous coals with some oil source potential.

The generation and continued existence of overpressure in the Delaware Basin, Texas [PDF]

open access: yes, 2007
The Delaware Basin, part of the larger Permian Basin, contains important hydrocarbon plays. Permian strata contain 71% of in-place oil and 53% of in-place gas, with the remainder hosted in the Lower Palaeozoic.

The Effects of Student Success Workshops on Undergraduate Hispanic STEM Students on the U.S.-Mexico Border

open access: yesIAFOR Journal of Education, 2019
The goal of the College of Arts & Sciences Community-aid (CASC-aid) project, a National Science Foundation grant funded study (2016-2021), is to develop, implement, and evaluate a program that fosters a community of academic success for Hispanic STEM ...

Spatial and temporal evolution of a coastal erg margin: the Middle Jurassic Page Sandstone, southern Utah, USA

open access: yesSedimentology, EarlyView.
ABSTRACT Aeolian deflationary events are erosive to static stages where sediment supply is insufficient to support bedform migration and preservation in the rock record. In the vicinity of shallow‐marine environments, inland rises of relative water table and associated generation of deflationary super surfaces may be driven by the onset of ...
