Wave Propagation in Infinituple-Porosity Media

期刊: JOURNAL OF GEOPHYSICAL RESEARCH-SOLID EARTH, 2021; 126 (4)

The fractal texture (or fabric) of porous media, which supports fluid flow at different scales, is the main cause of wave anelasticity (dispersion and......

Refining Higher Modes of Rayleigh Waves Using Seismoelectric Signals Excited by a Weight-Drop Source: Study From Numerical Simulation Aspect

期刊: JOURNAL OF GEOPHYSICAL RESEARCH-SOLID EARTH, 2021; 126 (5)

Effective extraction of higher mode dispersion information has been a research hotspot in the study of surface waves. In this study, we introduce a no......

Petrogenesis of Himalayan Leucogranites: Perspective From a Combined Elemental and Fe-Sr-Nd Isotope Study

期刊: JOURNAL OF GEOPHYSICAL RESEARCH-SOLID EARTH, 2021; 126 (8)

The petrogenesis of Himalayan leucogranites remains crucial for understanding the thermal and tectonic evolution of the Himalayan orogen. To understan......

Three-Dimensional Inversion of Magnetotelluric Data for a Resistivity Model With Arbitrary Anisotropy

期刊: JOURNAL OF GEOPHYSICAL RESEARCH-SOLID EARTH, 2021; 126 (8)

Electrical anisotropy is increasingly recognized as an important aspect of the resistivity models required to explain magnetotelluric (MT) observation......

Authigenic Iron Sulfides Indicate Sea-Level Change on the Continental Shelf: An Illustration From the East China Sea

期刊: JOURNAL OF GEOPHYSICAL RESEARCH-SOLID EARTH, 2021; 126 (3)

Although sea-level is the primary control over sedimentary architectures on continental shelves, deciphering such changes is still challenging, except......

Extraction of Multimodal Dispersion Curves From Ambient Noise With Compressed Sensing

期刊: JOURNAL OF GEOPHYSICAL RESEARCH-SOLID EARTH, 2021; 126 (6)

We propose a compressed sensing (CS) method for extracting multimodes from ambient noise. We solve the CS inverse problem by using two methods: an l(1......

Postseismic Deformation and Afterslip Evolution of the 2015 Gorkha Earthquake Constrained by InSAR and GPS Observations

期刊: JOURNAL OF GEOPHYSICAL RESEARCH-SOLID EARTH, 2021; 126 (7)

Mascon products derived from Gravity Recovery and Climate Experiment satellite gravimetry data are widely used to study the Greenland ice sheet mass b......

3D Geodynamic Models for HP-UHP Rock Exhumation in Opposite-Dip Double Subduction-Collision Systems

期刊: JOURNAL OF GEOPHYSICAL RESEARCH-SOLID EARTH, 2021; 126 (8)

The dynamics of high pressure (HP) and ultra-high pressure (UHP) rock exhumation in opposite-dip double subduction-collision systems remain enigmatic.......

Viscous Effects on the Particle Size Segregation in Geophysical Mass Flows: Insights From Immersed Granular Shear Flow Simulations

期刊: JOURNAL OF GEOPHYSICAL RESEARCH-SOLID EARTH, 2021; 126 (8)

Size segregation is a common feature in geophysical mass flow deposits and is an active process during motion. The presence of interstitial fluids in ......

Dynamic Evolution of Induced Subduction Through the Inversion of Spreading Ridges

期刊: JOURNAL OF GEOPHYSICAL RESEARCH-SOLID EARTH, 2021; 126 (3)

Lithospheric weakness is essential in subduction initiation. Spreading ridges are divergent plate boundaries which may represent lithospheric weakness......
