Repeating Low Frequency Icequakes in the Mont‐Blanc Massif Triggered by Snowfalls
Journal of Geophysical Research: Earth Surface, Volume 127, Issue 12, December 2022., 2022 Abstract Deformation mechanisms of glaciers are highly sensitive to basal temperature; the motion of temperate glaciers is dominated by basal slip while cold‐based glaciers deform mainly by internal creep. While basal slip is usually aseismic, unstable slip sometimes occurs and can be detected by seismometers.

Study on Mine Earthquake Prediction Based on Numerical Simulation of Rock Fracture Evolution
Energy Science &Engineering, EarlyView.This study analyzes the geomechanical behavior and fracture evolution of overlying strata to prevent rock bursts and identify mine earthquake sources. By establishing a refined stope model and applying the “O–X” fracture mechanics model, combined with microseismic monitoring data, this study reveals the spatiotemporal evolution laws of strata migration

Tectonics, Volume 41, Issue 12, December 2022., 2022 Abstract Orogenic wedges are common at convergent plate margins and deform internally to maintain a self‐similar geometry during growth. New structural mapping and thermochronometry data illustrate that the eastern Greater Caucasus mountain range of western Asia undergoes deformation via distinct mechanisms that correspond with contrasting lithologies ...

Recycling Argon through Metamorphic Reactions: the Record in Symplectites [PDF]
, 2018 The 40Ar/39Ar ages of metamorphic micas that crystallized at high temperatures are commonly interpreted as cooling ages, with grains considered to have lost 40Ar via thermally-driven diffusion into the grain boundary network.

Energy Science &Engineering, EarlyView.Flowchart of prediction method for natural fractures based on the secondary rescaled range analysis. ABSTRACT Currently, there are various methods for predicting natural fractures using logging data, however these methods are primarily for predicting the number and location of fractures. This is making it difficult to determine fracture types.

A Hibonite-Pyroxene Spherule in Allan Hills 77307 (CO3.03): Petrography and Mineralogy [PDF]
arXiv, 2017 Hibonite-pyroxene spherules are an extremely rare kind of refractory inclusion that show a wide range of exotic isotopic properties despite their defining similarity and simplicity in morphology and mineralogy. One such, relatively large (about 120 micron diameter), inclusion has been found in one of the most pristine meteorites, Allan Hills 77307 (a ...
