Palynology of the Kazanian stratotype section (Permian, Russia): palaeoenvironmental and palaeoclimatic implications

open access: yes, 2014
Palynomorph assemblages reflect changes in land plant communities and are thus significant proxies to interpret palaeoenvironmental and palaeoclimatic changes. The Middle Permian of the East European Platform is crucial to the understanding of marine and

An Examination of Subsidence in North-East England due to the Dissolution of Sub-Surface Gypsum using the Shallow Seismic Reflection Technique [PDF]

open access: yes, 2009
Along a narrow swath from Nottingham through to Hartlepool, broad shallow depressions up to 100m in diameter and, more rarely, scarp-edged subsidence hollows are observed.

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 ...

Permian-Triassic boundary at El Antimonio, Sonora, Mexico

open access: yesRevista Mexicana de Ciencias Geológicas, 2018
Newly discovered fossils indicate the Permian-Triassic boundary is in the lower Antimonio Formation. A brachiopod-dominated assemblage collected 40 m above the Monos-Antimonio Formations contact indicates a middle Permian (Guadalupian) age, and ...

Early Permian to Middle Triassic Formation petroleum potentials of Sydney Basin, Australia: A geochemical analysis

open access: yesOpen Geosciences
The organic geochemical and petrological analyses of calculated vitrinite reflectance of the Early Permian to Middle Triassic Formation section of the Sydney Basin in Australia have revealed the source for the widely distributed oil and gas shows in the ...

Late Cenozoic Sediment Provenance in the Northern Canterbury Basin, Aotearoa New Zealand

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 4, December 2026.
Late Cenozoic strata of the northern Canterbury Basin record uplift and erosion of mountain ranges adjacent to the transition from oblique subduction to strike‐slip on the Australian–Pacific plate boundary. Using the provenance of conglomerate clasts and sandstone samples, we reconstruct sediment transport pathways and, by inference, exhumation and ...

The Asymmetric Development of Remote Areas in Texas

open access: yesRural Sociology, Volume 91, Issue 4, December 2026.
ABSTRACT Drawing on the reciprocal dynamics of the growth machine framework, we test whether there was a bidirectional association between road construction and land development in remote, non‐metropolitan census tracts in Texas between 2010 and 2019, during a time when these areas experienced countering land‐use pressures from resource extraction ...
