Naturally etched tracks in apatites and the correction of fission track dating [PDF]

Radiation Measurements, 1999
Abstract Naturally etched tracks have been found in apatites from the rapid cooled, high-level Kunon pluton in the Zhangzhou Igneous Complex, SE China. This is manifested by the fact that the apatite fission track (FT) age derived from conventional counting of spontaneous and induced tracks yields a result of 140±6.5 Ma, which is much older than the ...

Eocene Tectonic Change in the South Pacific Caused Exhumation of the Transantarctic Mountains in Northern Victoria Land, Antarctica

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
Apatite fission‐track and (U‐Th)/He data indicate rapid exhumation of northern Victoria Land at 40–30 Ma, correlating with opening of Adare Trough at 43–28 Ma. Exhumation was greatest close to the Ross Sea, consistent with other regions of the Transantarctic Mountains.

Thermo‐Tectonic History of Archean Basement Rocks in the Aktash Tagh, Southeastern Tarim Craton: Constraints From Zircon U‐Pb, Zircon and Apatite Fission‐Track Dating

Geochemistry, Geophysics, Geosystems
Stable craton lithosphere can undergo complex tectonic events at its margins due to peripheral tectonic activity. In this study, we conducted a comprehensive analysis of zircon U‐Pb dating, apatite and zircon fission‐track thermochronology on the Aktash ...

The Early Cretaceous extensional deformation in the southeastern Beishan Range, central Asia: Constrains from 2D seismic reflection profile interpretation and apatite fission track thermochronology

Dizhi lixue xuebao, 2023
Objective  The Beishan Range occupies a key position in Central Asia. This study aims to deepen the understanding of the timing, intracontinental deformation processes, and their dynamic mechanisms in the Late Mesozoic on the southern margin of the ...

Electron Spin Resonance Thermochronometry Indicates Quaternary Activity of the Brenner Fault (Eastern Alps)

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract The Brenner Fault is one of the most important normal faults in the Eastern Alps as it accommodates uplift and lateral extrusion of the Tauern Window. Consequently, understanding its kinematic history is important for studying the dynamics of the Eastern Alps, in particular the Tauern Window.

Comment on Nixon, A. L. et al. (2022) on Intracontinental Fault Reactivation in High Heat Production Areas of Central Australia: Insights From Apatite Fission Track Thermochronology

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 2, February 2026.
Abstract Concerning our publication Intracontinental fault reactivation in high heat production areas of central Australia: insights from apatite fission track thermochronology we have identified the presence of rmr0 values that are erroneously high, due to an error in the code used to calculate these values from grain chemistry.

Geochemistry of Syntectonic Carbonate Veins Within Late Cretaceous Turbidites, Hikurangi Margin (New Zealand): Implications for a Mid‐Oligocene Age of Subduction Initiation

Geochemistry, Geophysics, Geosystems, 2022
We document the geochemistry of calcite veins in the Late Cretaceous Tikihore Formation (Raukumara Peninsula, New Zealand) to characterize their fluid composition and source and to help establish the age of subduction initiation at the Hikurangi margin ...

From Collision to Subduction: Thermal‐Kinematic Inversions Constrain Plate Boundary Structure and Dip‐Slip Activity in Southwestern New Zealand

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract Constraints on three‐dimensional fault system geometry and kinematics are required to understand both long‐term tectonics and contemporary seismic hazard. In many cases, these parameters must be inferred from a combination of different data or analyses.

Timing and Style of Tectonic Assembly and Exhumation of the McHugh Complex Within the Chugach‐Kodiak Accretionary Wedge, Alaska

Tectonics, Volume 45, Issue 2, February 2026.
Abstract Accretionary complexes are key archives of subduction zone processes, preserving records of forearc growth, deformation, and tectonic reorganization. The Chugach–Kodiak accretionary complex of southern Alaska records Jurassic to Cretaceous underplating at shallow to intermediate subduction conditions. The McHugh Complex, an imbricated sequence
