Intracontinental Fault Reactivation in High Heat Production Areas of Central Australia: Insights From Apatite Fission Track Thermochronology

Geochemistry, Geophysics, Geosystems, 2022
Pervasive intracontinental orogenesis during the Paleozoic has been widely recognized in the metamorphic and structural records of the Aileron Province and Amadeus Basin in central Australia, commonly attributed to the Ordovician–Carboniferous Alice ...

Constraints on Cenozoic tectonics in the southwestern Longmen Shan from low-temperature thermochronology [PDF]

Lithosphere, 2013
The Longmen Shan, located at the boundary between the Tibetan Plateau and the Sichuan Basin, has received considerable attention following the 2008 Wenchuan earthquake. However, the tectonic history of the southwestern segment of the range has remained poorly constrained.

Geochemical Disequilibrium at the Brittle‐Ductile Transition

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 4, April 2026.
Abstract We investigate the microtextural, microchemical, and isotopic effects of late‐stage ductile deformation in quartzite mylonites and kyanite–muscovite–quartz veins from the Raft River shear zone (Utah). Quartz microstructures record pervasive disequilibrium, expressed by unannealed features including undulatory extinction, deformation lamellae ...

The chronology and tectonic style of landscape evolution along the elevated Atlantic continental margin of South Africa resolved by joint apatite fission track and (U-Th-Sm)/He thermochronology [PDF]

Atlantic-type continental margins have long been considered “passive” tectonic settings throughout the entire postrift phase. Recent studies question the long-term stability of these margins and have shown that postrift uplift and reactivation of ...

Opposing shear senses in a subdetachment mylonite zone: Implications for core complex mechanics [PDF]

, 2010
[1] Global studies of metamorphic core complexes and low‐angle detachment faults have highlighted a fundamental problem: Since detachments excise crustal section, the relationship between the mylonitic rocks in their footwalls and the brittle deformation

Volcanic History of Rodrigues Island and Its Relationship With the Central Indian Ridge and the Réunion Hotspot

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 4, April 2026.
Abstract Many intraplate volcanic chains are explained as hotspot trails formed by plate motion over mantle plumes, yet some deviate from this model. The Rodrigues Ridge, a volcanic lineament extending eastward from the Réunion hotspot track toward the Central Indian Ridge (CIR), is one such case.

Early Quaternary Tectonic Transformation of the Helan Shan: Constraints Due To Quantitative Geomorphology

Frontiers in Earth Science, 2022
The Helan Shan is located on the front edge of the expanding Tibetan Plateau. However, how the topography here responds to this propagation and its precise time constraints remain unknown.

Thermal structure and exhumation history of the Lesser Himalaya in central Nepal [PDF]

, 2004
The Lesser Himalaya (LH) consists of metasedimentary rocks that have been scrapped off from the underthrusting Indian crust and accreted to the mountain range over the last ~20 Myr. It now forms a significant fraction of the Himalayan collisional orogen.
