Middle Neoproterozoic (Tonian) Polar Wander of South China: Paleomagnetism and ID-TIMS U-Pb Geochronology of the Laoshanya Formation J. Geophys. Res. Solid Earth (IF 3.9) Pub Date : 2024-04-23 Justin A. D. Tonti-Filippini, Boris Robert, Élodie Muller, André N. Paul, Fabian Dellefant, Michael Wack, Jun Meng, Xixi Zhao, Urs Schaltegger, Stuart A. Gilder
Paleomagnetic records of middle Neoproterozoic (820 to 780 Ma) rocks display high amplitude directional variations that lead to large discrepancies in paleogeographic reconstructions. Hypotheses to explain these data include rapid true polar wander (TPW), a geomagnetic field geometry that deviates from a predominantly axial dipole field, a hyper-reversing field (>10 reversals/Ma), and/or undiagnosed

The ocean carbon reservoir controls atmospheric carbon dioxide (CO2) on millennial timescales. Radiocarbon (14C) anomalies in eastern North Pacific sediments suggest a significant release of geologic 14C-free carbon at the end of the last ice age but without evidence of ocean acidification. Using inverse carbon cycle modeling optimized with reconstructed atmospheric CO2 and 14C/C, we develop first-order

On the Stability of Mantle-Sensitive P-Wave Interference During a Secondary Microseismic Event Geophys. Res. Lett. (IF 5.2) Pub Date : 2024-04-18 L. Tomasetto, P. Boué, L. Stehly, F. Ardhuin, H.-C. Nataf
Body wave extraction from oceanic secondary microseismic sources with seismic interferometry provides alternative information to better constrain the Earth's structure. However, sources' spatiotemporal variations raise concerns about travel time measurement robustness. Therefore, we study the cross-correlations’ stability during a single oceanic event. This study focuses on 3 days of data and three

Thermosphere UFKW Structures and Ionosphere Coupling as Observed by ICON Geophys. Res. Lett. (IF 5.2) Pub Date : 2024-04-18 Jeffrey M. Forbes, Xiaoli Zhang, Christoph R. Englert, Roderick Heelis, Michael H. Stevens, Brian J. Harding, John M. Harlander, Kenneth D. Marr, Jonathan J. Makela, Thomas J. Immel
Two ∼2-week Ultra-Fast Kelvin Wave (UFKW) events centered on days 158(203) during 2021 are investigated using winds, temperatures, plasma drifts and electron densities (Ne) measured by the Ionospheric CONnections (ICON) mission. Eastward-propagating longitudinal wave-1 (s = −1) structures with periods 2.5–4.0d, thought to mainly reflect Ultra-Fast Kelvin waves (UFKWs), reveal ±45 ms−1 zonal winds (U)

Evaluating the Rheological Controls on Topography Development During Craton Stabilization: Objective Approaches to Comparing Geodynamic Models J. Geophys. Res. Solid Earth (IF 3.9) Pub Date : 2024-04-18 Kristina Kublik, Claire A. Currie, D. Graham Pearson
Surface topography is an important yet largely neglected aspect of the early evolution of cratons. The lateral accretion of cratonic nuclei inevitably forms orogenic belts that subsequently provide a sediment source for large, resource-rich intracratonic basins, but to date, geodynamic models have focused exclusively on lithospheric root processes. Here we use two-dimensional thermal-mechanical models

An Updated Fault Coupling Model Along Major Block-Bounding Faults on the Eastern and Northeastern Tibetan Plateau From a Stress-Constrained Inversion of GPS and InSAR Data J. Geophys. Res. Solid Earth (IF 3.9) Pub Date : 2024-04-18 Dezheng Zhao, Chunyan Qu, Xinjian Shan, Wenyu Gong, Huihui Weng, Han Chen, Donglin Wu
Large block-bounding faults on the Tibetan plateau are significant geological structures that accommodate tectonic movements and accumulate stress, leading to large earthquakes. Quantifying the interseismic slip deficit rate helps to better assess the earthquake potential. We combine available InSAR (2015–2020) and interseismic GPS data to determine fault coupling along 14 major block-bounding faults

Monitoring Velocity Change Over 20 Years at Parkfield J. Geophys. Res. Solid Earth (IF 3.9) Pub Date : 2024-04-18 Kurama Okubo, Brent G. Delbridge, Marine A. Denolle
We monitored the time history of the velocity change (dv/v) from 2002 to 2022 to investigate temporal changes in the physical state near the Parkfield Region of the San Andreas Fault throughout the interseismic period. Following the coseismic decrease in dv/v caused by the 2003 San Simeon (SS) and the 2004 Parkfield earthquakes, the dv/v heals logarithmically and shows a net long-term increase in which

Introduction to the Distributional Finite Difference Method for 3D Seismic Wave Propagation and Comparison With the Spectral Element Method J. Geophys. Res. Solid Earth (IF 3.9) Pub Date : 2024-04-18 Chao Lyu, Yder Masson, Barbara Romanowicz, Liang Zhao
We have extended the distributional finite difference method (DFDM) to simulate the seismic-wave propagation in 3D regional earth models. DFDM shares similarities to the discontinuous finite element method on a global scale and to the finite difference method locally. Instead of using linear staggered finite-difference operators, we employ DFDM operators based on B-splines and a definition of derivatives

Importance of Water-Clay Interactions for Fault Slip in Clay-Rich Rocks J. Geophys. Res. Solid Earth (IF 3.9) Pub Date : 2024-04-18 Markus Rast, Claudio Madonna, Paul A. Selvadurai, Quinn C. Wenning, Jonas B. Ruh
Clay-rich rocks are integral to subduction zone dynamics and of practical importance, for example, as barriers in nuclear waste and CO2 repositories. While the effects of swelling strain on the self-sealing capabilities of these rocks are relatively well-established, the implications of polar fluids interacting with charged clay particles on the frictional behavior, and the role of swelling stress
