Summary: Back-arc basins are extensional structures that can exhibit narrow or wide-rift extension. The style of back-arc rifting is controlled by the relative rates of slab-pull force and convective thinning and thermal weakening of the overriding plate. A high subducting plate velocity leads to narrow back-arc rift, while a low subducting plate velocity allows for wide rifting.

Summary: The Permo-Triassic period in the Chinese North Pamir is characterized by well-preserved volcano-sedimentary sequences, providing important insights into the geodynamic evolution of Asia's pre-Cimmerian southern margin. Permian volcanism in the region was mainly pyroclastic and mafic to intermediate, while Triassic volcanic activity coincided with major Cimmerian intrusive events to the south. This suggests a complex tectonic history involving subduction, magmatic activity, and back-arc extension in the region.

Summary: This study focuses on the stratigraphic development of the Jameson Land Basin, revealing a predominance of continental deposits in the Middle-Late Triassic period. The presence of syn-rift succession and an intrabasinal high, along with evidence for Middle-Late Triassic rifting in East Greenland, were identified. The provenance data suggest sediment sourcing from both the western and eastern basin margins during deposition, with the western source area becoming dominant later on.

Summary: The Ogaden Basin in Ethiopia is a large sedimentary basin with significant potential for hydrocarbon resources. Previous studies have mainly focused on the sedimentology and lithostratigraphy of the basin, while this study provides an integrated sequence stratigraphic analysis of the Karoo section using seismic reflection and well data. The study suggests that tectonic control plays a major role in the formation of the basin and the distribution of reservoirs.

Summary: The study investigates the environmental response to external forcings on continental successions at the southeast margin of the Central European Basin System in Germany, integrating high-resolution core-logging and quantitative sedimentary petrography. Environmental changes are accentuated by variations in sediment composition, suggesting distinct drainage evolutions regulated by upstream climate and tectonic controls.

Summary: This study investigates the relationship between the distribution of Cambrian source rocks and paleotopography using various data analysis methods. The results show that there was extensive thermal subsidence in the Nanhua-Cambrian sequences and the Precambrian basement inherited the landform after the Nanhua continental rifting. A major transgression occurred during the Cambrian in the Tarim Basin, and source rocks were deposited on the slopes of the inherited paleotopography.

Summary: The Tyrrhenian back-arc basin developed as a result of the E-ward migrating Apennine fold-and-thrust belt, with debate surrounding the existence of a >200 km long transform zone separating its northern continental crust from the central/southern oceanic crust production. A branch of the presumed transform zone, known as the Ponza-Alife accommodation zone, played a role in the development of the back-arc extension stage through lateral juxtaposition of different rift domains in the subducting plate. Seismic lines and new data have been used to better understand the pre-orogenic and syn-orogenic architecture of the subducting plate in this region.

Summary: This study used sandbox analogue experiments to investigate the geometric and kinematic evolution of two nearby, sometimes intersecting, grabens and found different formation mechanisms. The results showed that when VDs are initially close, a wide graben is formed, while when the spacing between VDs is greater, the grabens develop independently.

Summary: The Ruvu Basin in Tanzania, which is not well-studied, contains important records of the Gondwana supercontinent. This study conducted a comprehensive palynological investigation on the Makarawe-1 well in the Ruvu Basin, revealing four distinct palynologic intervals and establishing correlations with other formations. The findings provide insights into the stratigraphic framework and distant correlations using palynology.

Summary: Geochemical study in the siliciclastic sediments of the Satpura Basin in India provides insights into palaeoclimate, provenance, tectonic settings, and basin evolution. The sediments from different formations show variations in source, climatic conditions, and tectonic activity.

Summary: The study analyzed the structural units, tectonic features, and geodynamics of the Nan'an Basin based on newly acquired seismic data. The findings suggest that the basin is a northeast-southwest oriented rift basin, rather than a pull-apart basin induced by strike-slip faults. It provides evidence for the importance of regional strike-slips and orthogonal displacement during basin development and deformation. Rating: 8/10.

Summary: The Chachil depocenter located in the Andean foreland is characterized by NNW and NE-striking normal faults controlling its extensional architecture. The rift structure is related to the reactivation of Paleozoic discrete basement anisotropies, with local ENE extension possibly resulting from the refraction of the regional NNE to NE-oriented extension further north in the basin.

Summary: The study finds that the shorelines of the Makgadikgadi Basin in northeastern Botswana are controlled by three major faults, indicating the influence of tectonic activity on the basin's morphology. The Humboldt Belt and the Limpopo Belt are identified as the geological background of these faults, and the pronounced curvature of the Humboldt Belt leads to the eastward curvature of the faults. Moreover, seismic data shows a change in regional extension direction from northwest-southeast to northeast-southwest. These findings are important for understanding the formation of the Makgadikgadi Basin and the current tectonic regime of Botswana.

Summary: The Beaufort Group in South Africa's Main Karoo Basin is an important site that provides a continuous record of fluvio-lacustrine sedimentation from the Middle Permian to the Middle Triassic. Fossils found in this area, including a diverse range of vertebrate taxa, offer an ideal opportunity to study temporal and geographical variations of local hydrology using stable isotopes. While previous studies have addressed questions about temporal and biological variations in oxygen stable isotope ratios, the geographic variation of bioapatite-recorded 818Op across the Permo-Triassic of South Africa has not yet been examined.

Summary: This study investigates the petrographic features and possible metamorphic conditions of rocks in the Kelebia basement area in Szeged Basin. The results suggest that the basement in this area has a very low- to low-grade (ca. 300 degrees C) metamorphic imprint. Deformation characteristics and fluid migrations are also observed, indicating the influence of orogenic events on the basement structure.
