Matthieu Amor et al.
Magnetotactic bacteria (MTB) produce single-stranded or multi-stranded chains of magnetic nanoparticles that contribute to the magnetization of sediments and rocks. Their magnetic fingerprint can be detected in ancient geological samples an...
Hydrothermal Alteration of the Ocean Crust and Patterns in Mineralization With Depth as Measured by Micro-Imaging Infrared Spectroscopy [0.03%]
洋壳的水热改变以及通过显微成像红外光谱所测量的深度矿物化模式
Rebecca N Greenberger,Michelle Harris,Bethany L Ehlmann et al.
Rebecca N Greenberger et al.
Processes for formation, cooling, and altering Earth's ocean crust are not yet completely understood due to challenges in access and sampling. Here, we use contiguous micro-imaging infrared spectroscopy to develop complete-core maps of mine...
Insights Into the Origin and Deformation Style of the Continental Moho: A Case-Study From the Western Alps (Italy) [0.03%]

Several hypotheses on the origin of the continental Moho are still debated and multiple mechanisms may contribute to its formation. Here, we present quantitative estimation of the seismic properties and anisotropy of the crust-mantle transi...

The cause for the damping of the Earth's free core nutation (FCN) and the free inner core nutation eigenmodes has been a matter of debate since the earliest reliable estimations from nutation observations were made available. Numerical stud...
Microphysical Modeling of Carbonate Fault Friction at Slip Rates Spanning the Full Seismic Cycle [0.03%]
涵盖完整地震周期滑移率的碳酸盐岩断层摩擦的微物理模拟
Jianye Chen,A R Niemeijer,Christopher J Spiers
Jianye Chen
Laboratory studies suggest that seismogenic rupture on faults in carbonate terrains can be explained by a transition from high friction, at low sliding velocities (V), to low friction due to rapid dynamic weakening as seismic slip velocitie...

The early Earth was marked by at least one global magma ocean. Melt buoyancy played a major role for its evolution. Here we model the composition of the magma ocean using a six-component pyrolite melt, to which we add volatiles in the form ...
Flow-to-Friction Transition in Simulated Calcite Gouge: Experiments and Microphysical Modeling [0.03%]
模拟文石碎裂流变的流动到摩擦转换：实验和微物理建模

A (micro)physical understanding of the transition from frictional sliding to plastic or viscous flow has long been a challenge for earthquake cycle modeling. We have conducted ring-shear deformation experiments on layers of simulated calcit...
Acoustic Energy Release During the Laboratory Seismic Cycle: Insights on Laboratory Earthquake Precursors and Prediction [0.03%]

David C Bolton et al.
Machine learning can predict the timing and magnitude of laboratory earthquakes using statistics of acoustic emissions. The evolution of acoustic energy is critical for lab earthquake prediction; however, the connections between acoustic en...
Seismic Crustal Structure and Morphotectonic Features Associated With the Chain Fracture Zone and Their Role in the Evolution of the Equatorial Atlantic Region [0.03%]
与链断裂带有关的地震 crust 结构和地貌构造特征及其在赤道大西洋地区演化中的作用
Milena Marjanović,Satish C Singh,Emma P M Gregory et al.
Milena Marjanović et al.
Oceanic transform faults and fracture zones (FZs) represent major bathymetric features that keep the records of past and present strike-slip motion along conservative plate boundaries. Although they play an important role in ridge segmentat...
Seasonal and Long-Term Groundwater Unloading in the Central Valley Modifies Crustal Stress [0.03%]
中央山谷的季节性和长期地下水位下降改变了地壳应力状态

G Carlson et al.
Changes in terrestrial water content cause elastic deformation of the Earth's crust. This deformation is thought to play a role in modulating crustal stress and seismicity in regions where large water storage fluctuations occur. Groundwater...
