Summary: This study uses apatite fission track data to investigate the exhumation history of the Bogda Range in the Eastern Tianshan. The results show that the Bogda experienced three episodes of cooling during the Late Triassic, Late Cretaceous, and Late Miocene, possibly related to its formation, tectonic extension in the central-eastern Asian regime during the Cretaceous, and the India-Eurasia collision since the beginning of the Cenozoic.

Summary: The Peel Plateau in the northern Canadian Cordillera has experienced multiple burial and unroofing events since the Phanerozoic, with evidence from unconformities. This study uses apatite fission-track thermochronology to investigate the thermal history of the region. The results suggest that the uppermost Paleozoic strata reached maximum burial temperatures in the Triassic and were reheated under a Cretaceous-Paleocene foreland basin.

Summary: This study used different dating methods to determine the timing of fault activity, and the results indicate that the Guangsan fault was still active during the period of 70-65 million years ago, leading to rapid uplift.

Summary: The Altai Mountains, located thousands of kilometers away from plate margins, are a young and steep mountain belt. The Fuyun area, at the southern margin of the Chinese Altai, provides important insights into the Meso-Cenozoic deformation and exhumation history of the Altai. New data on apatite U-Pb, trace element, and fission track analysis shed light on the Meso-Cenozoic tectonic history, suggesting metasomatism in the Middle-Late Jurassic and rapid cooling and exhumation during the early Late Cretaceous.

Summary: This study re-evaluates the thermo-tectonic evolution of the Bogda Shan mountain range using apatite fission track thermochronology. The results suggest slow to moderate basement cooling during the early Mesozoic, explaining the preservation of low-relief Mesozoic erosion surfaces. In addition, partial resetting of the apatite fission track system during the Cretaceous and coincident ages with exhumation pulses in the Chinese North Tianshan were observed. Based on a comprehensive summary of published data, the authors argue for a Mesozoic building of the Bogda-Balikun-Harlik mountain chain and relatively modest Cenozoic exhumation.

Summary: The Daba Shan orocline, located in the northeastern margin of the Sichuan Basin, is believed to be a foreland thrust-fold belt of the Qinling Orogen since the Late Triassic. Understanding the exhumation history of the rocks is crucial to determine the development of this orocline structure. Detrital apatite fission-track dating of modern river sands reveals the regional exhumation history of the Daba Shan orocline, showing four age peaks that can be attributed to tectonic exhumation.

Summary: Fission events in minerals produce damage tracks that contain critical information about events occurring over different time scales. However, the exact location of fission occurrence along these tracks has never been identified. This study utilizes a novel technique to observe unexpectedly narrow fission tracks near the fission event site, contrary to the conventionally assumed largest diameter. These narrow tracks provide vital spatial information for understanding atomic-scale processes, such as track formation and annealing, with significant implications for fission track thermochronology.

Summary: This study used apatite fission-track analysis to determine the uplift and exhumation history of the eastern Qilian Shan in the Tibetan Plateau. The results showed that the main stage of growth and thickening occurred during the Middle Jurassic-Early Cretaceous, and the Late Cretaceous was a period of intense uplift and deformation. The cooling of the eastern margin of the Qilian Shan during the Late Eocene-Early Miocene was attributed to crustal extension. The study also found no evidence of intense reactivation in the late Cenozoic period in the Xiji region. These findings have implications for regional hydrocarbon exploration.

Summary: This study investigates the thermal and tectonic evolution of the West African continental margins through new apatite fission-track (AFT) data analysis in Guinea and Ivory Coast. The results reveal the thermal effect of the Central Atlantic Magmatic Province (CAMP), rapid cooling along the coast during the early to mid-Cretaceous period, and moderate cooling across longer wavelengths.

Summary: Fission-track annealing models can be applied to geological studies to study physicochemical processes. Various models, such as parallel and fanning models, have been developed to describe track length reduction. The fanning curvilinear model fits laboratory data better and is more consistent with geological evidence, indicating that it provides a more accurate representation of the complex recombination mechanisms.

Summary: The research conducted on the West Siberian Basin (WSB) using apatite fission track (AFT) thermochronology has revealed episodes of tectonic reactivation in the Mesozoic and Cenozoic eras. The analysis of thirteen basement samples showed mainly Cretaceous cooling ages, indicating far-field effects from tectonic processes on the southern and eastern boundaries of Eurasia.

Summary: This study provides new AFT and AHe ages for samples collected in the northern Dom Feliciano Belt and performs inverse modeling, revealing contrasting temperature evolution between the northern and southern segments. It also shows that volcanic rocks in the Florianopolis Fracture Zone raised and sustained higher basement temperatures until 30 Ma.

Summary: Using apatite fission track, apatite (U-Th-Sm)/He, and zircon (U-Th)/He thermochronology, this study reveals that the Nyika Plateau has been an isolated topographic feature since at least the Permo-Triassic, potentially forming as a horst between two large Karoo grabens. The thermal history of Nyika, along with the Livingstone Plateau, suggests the possibility of a contiguous highland prior to the formation of the Neogene Malawi rift.

Summary: Studies have shown that there is considerable variation in confined fission-track length measurements in apatite, primarily due to differences in analyst decision-making. This study explores the influence of different etching sequences, track selection approaches, and analytical methods on track length and density measurements. The experiments reveal that tracks selected using the sufficiently-etched criterion are slightly under-etched compared to the full latent track zone, and tracks measured using exclusively transmitted light have a lower efficiency in finding dipping tracks. The study proposes a two-step etching procedure that may provide more reproducible data by reducing the impact of human decision-making.

Summary: In this study, the Arrhenius equations are generalized and synthesized to create a composite equation that allows for the generation of Arrhenius-type equations by manipulating parameters and functions. Three new models for annealing of fission tracks in apatite are presented, and their extrapolation to the geological timescale is discussed.
