Sediment‐stressed reefs over the past 420 Myr

open access: yesThe Depositional Record, EarlyView.
In order to fully elucidate the relationship between siliciclastic sedimentation and reef development, there needs to be a significant step change in how we record ancient and recent reefs. Only through the collection of constrained quantitative data, we can progress beyond the largely conjectural associations postulated for many ancient reefal systems.

Breedon Hill [PDF]

open access: yes, 2013
Breedon Hill forms one of the most prominent features in the landscape of north-west Leicestershire, standing up 50 m above the surrounding ground. That it has been a major landmark throughout recorded history is suggested by its name, which is derived ...

Triassic

open access: yes
Abstract The Triassic of the Netherlands records a complex history of episodic tectonism, changing climate and marine flooding of a continental interior basin. The section is divided into two groups separated by the Base Solling Unconformity: the latest Permian – Olenekian Lower Germanic Trias, and Olenekian – Norian Upper Germanic Trias.

Slip versus dilation tendency parameter space as a tool for prospecting structurally controlled geothermal systems in greenfield: insights from the greater Ruhr region

open access: yesDeep Underground Science and Engineering, EarlyView.
This study highlights that with the static and time‐dependent evolution of slip versus dilation tendency parameter space, structurally controlled deep geothermal systems can be selected within areas of higher permeability and lower seismic hazard. Abstract Faults play a vital role in the Earth's hydraulic system by facilitating fluid flow when dilating

Fossilized gill soft tissues in Mesozoic freshwater unionoid bivalves: reinvestigation and new evidence of the evolution of adaptation to the freshwater environment

open access: yesActa Palaeontologica Polonica
Large freshwater unionoid bivalves today are a globally distributed and diverse group, with a history dating back to the Triassic. Their evolutionary success largely depends on their reproductive behavior, today, they all take maternal care via brooding ...

Evolution of the plants and invertebrates in the north of the Middle Siberia and environs at the Permian - Triassic boundary

open access: yesИзвестия высших учебных заведений: Геология и разведка, 2017
Five adjacent eco-stratigraphic units have been considered (listed here, from the bottom to the top): eco-zones Cordaites clercii ... Abiella subovata (7 dominants of the plain sedtmentation level), Quadrocladus pachyphyllus ...

Overview of geothermal resource exploration and development in North Africa

open access: yesDeep Underground Science and Engineering, EarlyView.
This article reviews geothermal exploration in North Africa, highlighting key activities, government policies, and exploration findings across Mauritania, Morocco, Algeria, Tunisia, Libya, and Egypt. The region's substantial geothermal potential, driven by tectonic activity, positions it to play a significant role in the global geothermal energy ...

A Triassic plesiosaurian skeleton and bone histology inform on evolution of a unique body plan

open access: yesScience Advances, 2017
The first plesiosaur skeleton from the Triassic informs about the evolutionary success of four-flippered marine reptile. Secondary marine adaptation is a major pattern in amniote evolution, accompanied by specific bone histological adaptations.

Pore Structure of Tight Sandstones With Different Sedimentary Microfacies in the Chang 6–Chang 9 Layers, Triassic Yanchang Formation, Wuqi Area, Ordos Basin

open access: yesEnergy Science &Engineering, EarlyView.
Taking the Chang 6–Chang 9 layers in the Wuqi area of the Ordos Basin as a case study, this study investigates the pore characteristics of tight sandstones formed under different sedimentary microfacies. The results indicate that tight sandstones associated with distinct sedimentary microfacies exhibit significant variations in pore types, pore size ...
