Mechanisms of near‐normal sea water dolomitisation: Mesohaline‐reflux or syn‐depositional?

The Depositional Record, EarlyView.
This study investigates the dolomitisation of the Eocene Dammam Formation on the Arabian Plate using petrographic, mineralogical, geochemical and isotopic analyses. The findings reveal two distinct dolomite types, formed primarily through normal‐to‐mesohaline sea water dolomitisation, challenging previous models such as sabkha‐meteoric mixing.

Study on spatiotemporal evolution of rocky desertification in the pilot zone for sustainable development: A case study of Gongcheng county

Carsologica Sinica
The karst area in Southwest China is an important region for the implementation of sustainable development strategies in China, as well as an area with extremely fragile ecological environment and concentrated distribution of rocky desertification. As a "

Carbonate sedimentology: An evolved discipline

The Depositional Record, EarlyView.
Abstract Although admired and examined since antiquity, carbonate sediment and rock research really began with Charles Darwin who, during a discovery phase, studied, documented and interpreted their nature in the mid‐19th century. The modern discipline, however, really began after World War II and evolved in two distinct phases.

Water Quality and Hydrogeochemical Characteristics of Some Karst Water Sources in Apuseni Mountains, Romania

Water, 2021
Human activities and natural factors determine the hydrogeochemical characteristics of karst groundwaters and their use as drinking water. This study assesses the hydrogeochemical characteristics of 14 karst water sources in the Apuseni Mountains (NW ...

Polygonal tepee structures of Arabia

The Depositional Record, EarlyView.
Tepee structures on Sheybarah Island form polygonal microbial cemented crusts in the intertidal. Radiocarbon dating suggests they formed in the Holocene and reflect minor sea‐level changes, highlighting their value as palaeoenvironmental indicators. Satellite surveys identified 126 polygonal features, including coral reefs that may have developed on ...

Linking PAHs concentration, risk to PAHs source shift in soil and water in epikarst spring systems, Southwest China

Ecotoxicology and Environmental Safety, 2023
A systematic assessment of the variations in the ecological risk of PAHs and the key emission sources controlling the variations is of great importance to human health and aquatic organisms. PAH concentrations, composition, source, and ecological risk in

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

Deep 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

Directional Deep Brain Stimulation for Parkinson's Disease: Results of an International Crossover Study With Randomized, Double‐Blind Primary Endpoint

Neuromodulation: Technology at the Neural Interface, EarlyView., 2021
Abstract Objective Published reports on directional deep brain stimulation (DBS) have been limited to small, single‐center investigations. Therapeutic window (TW) is used to describe the range of stimulation amplitudes achieving symptom relief without side effects.
