Logging Components Extraction Method and Anisotropy Recognition Based on 3D Holographic LWD Instrument [PDF]

Lithosphere
Addressing the challenges of extracting all electromagnetic logging components in a self-developed 3D holographic logging while drilling (LWD) tool using existing theoretical methods, this study focuses on the following core work: starting from a three ...

The influence of anisotropic electrical resistivity on surface magnetotelluric responses and the design of two new anisotropic inversions

Earth, Planets and Space, 2023
Using the 3-D axial anisotropy, the dipping anisotropy, and the azimuthal anisotropy as case studies, we investigated the influence of each anisotropic resistivity element on the magnetotelluric surface responses. To justify the strong and weak influence

In situ stress state from walkaround VSP anisotropy in the Kumano basin southeast of the Kii Peninsula, Japan

Geochemistry, Geophysics, Geosystems, 2011
To reveal the stress state within the Kumano basin, which overlies the Nankai accretionary prism, we estimated seismic anisotropy from walkaround vertical seismic profiling (VSP) data recorded at Site C0009 during Integrated Ocean Drilling Program (IODP)

Anisotropy and Deformation Processes in Southern California From Rotational Observations

Geophysical Research Letters, 2023
Seismic anisotropy in the upper mantle reveals geodynamic processes and the tectonic evolution of the Earth. The two most powerful methods, surface wave tomography, and shear‐wave splitting observations, cannot investigate the deep local anisotropy with ...

Azimuthal Seismic Anisotropy in the Upper Crust of the Japanese Islands Induced by the 2011 Tohoku‐Oki Megathrust Earthquake

Geophysical Research Letters, 2018
We investigated VP/VS changes in the upper crust of the Japanese islands after the 2011 MW9.0 Tohoku‐Oki megathrust earthquake. Abrupt VP/VS changes with azimuth‐dependent variations were observed after the megathrust earthquake. The VP/VS changes ranged

Azimuthal anisotropies as stringent test for nuclear transport models [PDF]

Nuclear Physics A, 1997
Azimuthal distributions of charged particles and intermediate mass fragments emitted in Au+Au collisions at 600AMeV have been measured using the FOPI facility at GSI-Darmstadt. Data show a strong increase of the in-plane azimuthal anisotropy ratio with the charge of the detected fragment.

The crustal deformation mechanism of southern Chuandian block: constrained by S wave velocity and its azimuthal anisotropy

Geoscience Letters
We construct the 3D Shear wave velocity and azimuthal anisotropy images in the southern Chuandian block using phase velocity dispersion of Rayleigh wave in the period of 5–45 s. The images show two extensive low-velocity zones with a depth range of 20–40
