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: 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: 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: 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 reveals considerable Paleozoic reactivation in central Australia, with low-temperature cooling in the Tennant region and Murphy Province during the Alice Springs Orogeny, and Triassic reactivation in the Aileron Province corresponding to the Hunter-Bowen Orogeny. The susceptibility of the Aileron Province to reactivation is attributed to high heat production and metasomatism.

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: Through studying the Nangqian Basin, the deformation and growth of the eastern Tibetan Plateau during the Mesozoic are discovered. The sedimentary sequences in the Nangqian Basin show three phases of coarse clastic deposition, indicating simultaneous regional deformation. The tectonic development history of the Nangqian region suggests that the growth of the Tibetan Plateau is episodic and synchronous but with varying amplitudes.

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: Products of onshore passive continental margin erosion are well preserved in offshore sedimentary basins, providing a recoverable record of onshore erosion history. Analysis of apatite fission track (AFT) data and Bayesian mixture modeling can help resolve thermal histories and changes in sediment provenance in response to tectonic evolution. Additionally, tracking changes in provenance with time using apatite U-Pb and compositional data aids in understanding the exhumation and burial history of the margin over a longer timescale.

Summary: The regional uplift of Madagascar is proposed to be generated and maintained by mantle dynamical processes. Through a combined analysis of multiple observational constraints, it is suggested that around 1 km of topography was formed during the Neogene period. Studies on rare earth element concentrations in Neogene rocks indicate partial melting of the mantle occurred at varying depths and temperatures.

Summary: The study demonstrates that oxalate-rich mineral accretions found in rock shelters can be used for radiocarbon dating of rock art, reliably determining the age of the art as well as serving as potential sources for paleoenvironmental archives. Results from the Kimberley region show that the synchronous formation of these accretions is broadly controlled by variations in regional environmental conditions.

Summary: Evidence suggests that during the Early to Middle Miocene, sea-level oscillations of approximately 40-60 m were caused by the loss of virtually all East Antarctic ice during peak warmth. The presence of a large West Antarctic Ice Sheet during the Early Miocene has been confirmed, highlighting a key step in the genesis of a marine-based West Antarctic Ice Sheet.

Summary: The continental margin of south to central Vietnam, influenced by the South China Sea rift, experienced a period of fast cooling between approximately 37 and 30 million years ago. This fast cooling coincided with a period of rapid extension in the East Sea region. Models suggest that the fast cooling was a result of accelerated erosion during the early stages of rifting, possibly with additional heating from underplating and/or hot mantle upwellings.

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: The LeMay Group accretionary complex in Alexander Island consists of deformed turbidites and thrust slices of ocean floor basalts. The age and provenance of this complex are uncertain, ranging from Carboniferous to Cretaceous. The accretion history is poorly established, but our geochronology and geochemistry analysis suggests its deposition, provenance, and accretion occurred during the Permian to mid-Triassic, mid-Cretaceous, and Early Jurassic respectively.

Summary: In order to understand the subduction history of the Paleo-Pacific plate beneath the East Asian margin, a study was conducted on the sediment provenance below West Sarawak, Borneo. The results suggest that there was a period of inactive subduction near Borneo during the Late Triassic, followed by slab shallowing subduction between 200 and 170 Ma, and then a period of widespread magmatism between c. 170 and 70 Ma indicating steepening of the Paleo-Pacific slab.

Summary: This study conducted a spatial assessment and mapping of flood hazards in the Sekondi-Takoradi Metropolis (STM) of Ghana using the Analytical Hierarchy Process (AHP) and geographical information system. The results indicate that about 12% of STM lands are in very high flood zones and 24% are in high flood zones. The lower portions of STM are identified as the most susceptible to inundation. These findings provide valuable insights for effective flood planning and prevention in STM.

Summary: The carbonatites from the Richat dome in Mauritania are unique and underdocumented geological features. This study provides insight into the mineralogy and petrogenesis of the carbonatites, revealing three identified types and their association with spinel-bearing peridotite. The geochemical characteristics of the Richat carbonatites are similar to other Cretaceous alkaline carbonatite occurrences in different regions, suggesting a common geological process. The reactivation of a deep pan-African lineament is considered a fundamental factor in the formation of the Richat carbonatites.

Summary: Twenty-one gastropod species have been identified in the Cenomanian deposits of Bellezma-Aures mountains, eastern Saharan Atlas, Algeria, with four of them recorded for the first time in the Batna mountains. These gastropods are mainly found in the 'Marnes de Smail' Formation, and their community changes may be attributed to minor sea-level fluctuations, sedimentation rate variations, and hydrodynamics. The paleobiogeographic distribution of these gastropod assemblages indicates a tethyan affinity and faunal exchange during that time interval.
