Well-Preserved Structure of Silicified Wood: A Case Study from Qitai Silicified Forest, NW China and Its Silicification Mechanisms

Plants
The Qitai silicified wood from Xinjiang, NW China, provides an exceptional archive for investigating the mechanisms of wood silicification. This study applies microscopy, scanning electron microscopy (SEM), and X-ray diffraction (XRD) to characterize the

Morphometric Analysis and Emplacement Dynamics of Folded Terrains at Avernus Colles, Mars

Remote Sensing
Folded, arcuate terrains on the surface of Mars provide insight into the volcanic properties of surface materials and emplacement dynamics. This research focused on the analysis of folded terrains in the chaotic-terrain Avernus Colles region, located ...

Laboratory-Scale Implementation of Standardized Reconstituted Geothermal Water for Electrochemical Investigations of Carbon Steel Corrosion

Metals
Currently, the demand for heat production by geothermal energy is increasingly strong amid the controversy surrounding non-renewable forms of energy. In France, the Dogger aquifer in the Paris Basin (DAPB) produces saline geothermal waters (GWs) that are

The sedimentary environment in the Ljubljansko barje basin during the pile-dwelling period

Arheološki Vestnik, 2011
Geological processes on the Ljubljansko barje basin after the Last Glacial Maximum are known merely on a general level. At few points more detailed circumstances are known, but this information is fragmented spatially and temporally. While artefacts from

Iron disproportionation in peridotite fragments from the mantle transition zone

Nature Communications
Previous high-temperature-pressure experiments predicted metallic iron’s potential presence in the deep mantle below 250 km, arising from ferrous disproportionation in silicates, which could profoundly impact the redox environment and physicochemical ...

Volcanism and basalt weathering drove Ordovician climatic cooling

Nature Communications
Causal connections among major Ordovician environmental and biological events (i.e., long-term climatic cooling, Hirnantian Glaciation, Great Ordovician Biodiversification Event, and Late Ordovician Mass Extinction) remain in debate, and the hypothesis ...
