Preliminary Results on Hydrogen Concentration Time Series in Spring Gases from the Pamir–Western Himalayan Syntaxis: Variability and Tectonic Instability

Applied Sciences
Identifying reliable geochemical signals that reflect crustal stress evolution remains a major challenge in earthquake monitoring. Spring fluids, due to their deep circulation and rapid response, provide an important window into fault-zone processes ...

Trace element detection in anhydrous minerals by micro-scale quantitative nuclear magnetic resonance spectroscopy

Nature Communications
Nominally anhydrous minerals (NAMs) composing Earth’s and planetary rocks incorporate microscopic amounts of volatiles. However, volatile distribution in NAMs and their effect on physical properties of rocks remain controversial. Thus, constraining trace

Deviatoric stress-induced metallization, layer reconstruction and collapse of van der Waals bonded zirconium disulfide

Communications Chemistry
In contrast to two-dimensional (2D) monolayer materials, van der Waals layered transition metal dichalcogenides exhibit rich polymorphism, making them promising candidates for novel superconductor, topological insulators and electrochemical catalysts ...

Earth Pressure

AbstractOn the most important wall of our diagnosis, a synthesis of the tension results is compared to a theorical approach. A particular focus is done on the elements located at the foot of the wall and interfering with the tension results.

Ancient Life’s Gravity and its Implications for the Expanding Earth

, 2012
Galileo Galilei emphasised in the 17th century how scale effects impose an upper limit on the size of life. It is now understood that scale effects are a limiting factor for the size of life.

Realistic Earth escape strategies for solar sailing

, 2005
With growing interest in solar sailing comes the requirement to provide a basis for future detailed planetary escape mission analysis by drawing together prior work, clarifying and explaining previously anomalies.

The Effects of Confining Pressure and Fluid Saturation on Ultrasonic Velocities in Rocks [PDF]

, 1985
Laboratory measurements of ultrasonic p- and S-wave velocities were made as a function of confining pressure for vacuum dry, benzene-, and water-saturated samples of Westerly granite, Bedford limestone, and Weber, Navajo, Berea, and Kayenta sandstones.

Experimental and modeling study of fluid pressure-driven fractures in Darley Dale sandstone

, 2004
We report measurements of acoustic emissions (AE) generated during formation and growth of pressure driven fractures in cylindrical samples of Darley Dale sandstone that were co-axially pre-drilled in order to allow an internal pressure to be applied.
