Scale-dependence of lithological control on topography: Bedrock channel geometry and catchment morphometry in western Scotland [PDF]
We propose that a scale-dependent topographic signature of erodibility arises due to fluvial and glacial erosion acting on different parts of the landscape at different times.

The evolution of electrical conductivity, mineral composition, and tensile behavior such as peak strength, average stiffness, and the energy evolution of the granite specimen under different HCl conditions are studied, analyzed as well as quantified, and investigated, respectively.

Based on acoustic emission response characteristics, it can be more accurate to identify the damage evolution process of coal under the combined dynamic and static loads, reveal the moment corresponding to coal damage, and identify the characteristics of coal failure. The research results are conducive to the further use of acoustic emission monitoring

Slip inversion along inner fore-arc faults, eastern Tohoku, Japan [PDF]
The kinematics of deformation in the overriding plate of convergent margins may vary across timescales ranging from a single seismic cycle to many millions of years.

Microscopic time‐dependent mechanical behavior of shale derived from nanoindentation
This study conducted grid nanoindentation creep tests to systematically analyze the microscopic creep behaviors of shale. Based on the analysis of creep strain rate sensitivity, the primary mechanism of microscopic creep in shale was found to be the extension and closure of microcracks.

Streamlined islands and the English Channel megaflood hypothesis [PDF]
Recognising ice-age catastrophic megafloods is important because they had significant impact on large-scale drainage evolution and patterns of water and sediment movement to the oceans, and likely induced very rapid, short-term effects on climate. It has

Elevated temperature effects on swelling pressure of compacted bentonite
We present a set of new experimental investigations on the effects of elevated temperature on the swelling pressure development of compacted bentonite. This research was motivated by an emerging interest in using bentonite as a plug material in oil and gas well abandonment.

Frictional behavior of talc-calcite mixtures [PDF]
Faults involving phyllosilicates appear weak when compared to the laboratory-derived strength of most crustal rocks. Among phyllosilicates, talc, with very low friction, is one of the weakest minerals involved in various tectonic settings.

Abstract The Paishanlou gold deposit lies along the northern margin of North China Craton gold province, the third largest Au province in China. The deposit is mainly hosted in Archean metamorphic rocks of the Jianping Group and is structurally controlled by two sets of ductile shear zones.
