Fault Interaction and Strain Partitioning Deduced From Deformed Fluvial Terraces of the Eastern North Qilian Foreland, NE Tibetan Plateau

Journal of Geophysical Research: Solid Earth, Volume 129, Issue 11, November 2024.
Abstract Faulting and folding of basement rocks together accommodate convergence within continental orogens, forming complex zones of intraplate deformation shaped by the fault interaction. Here we use the river terraces along the Dongda river to examine the tectonic deformation patterns of the hinterland and the foreland of the eastern North Qilian ...

The Bend on the Haiyuan Strike‐Slip Fault Leads to Segmented Activity of the Minle‐Damaying Thrust Fault in the Qilian Shan, the Northeastern Tibetan Plateau

Tectonics, Volume 43, Issue 8, August 2024.
Abstract The present tectonic regime of the Qilian Shan is dominated by large northeast and northwest striking strike‐slip faults and northwest striking thrust faults. Deformation distribution between the subparallel Haiyuan Strike‐slip Fault and the Minle‐Damaying Thrust Fault (MDF) is crucial for understanding the orogenic mechanism of the ...

Present‐Day 3D Crustal Deformation of the Northeastern Tibetan Plateau From Space Geodesy

Geophysical Research Letters, Volume 51, Issue 4, 28 February 2024.
Abstract High‐resolution present‐day earth surface deformation maps from satellites provide important data constraints, which help us better understand tectonic processes and analyze seismic hazards. Here, we use Sentinel‐1 Radar images (2014–2020) and accurate positioning measurements (2009–2019) to get a high‐resolution three‐dimensional earth ...

Geochemical characteristics of natural springs within the Lenglongling fault zone related to the Menyuan Ms 6.9 earthquake on January 8, 2022, NW China

, 2023
Geofluids from natural springs connect with the crust and/or mantle in many cases, and their geochemical anomalies could be significant for the study on faults activity and even earthquakes.
