Summary: English Summary: The rift structures of the Shanan and Chengbei sags in the Early Cretaceous and Paleogene periods were influenced by the Indosinian and Yanshanian tectonic movements. However, there is a lack of understanding regarding the basement structures and how they influenced the later rift development, which has hindered hydrocarbon exploration in the area. Through the analysis of seismic reflection data and onshore field data, it was found that the basement of the study area contains NW-striking low-angle fold-thrust belts from the Indosinian period and NE-striking high-angle thrusts from the Yanshanian period. These pre-existing structures had a significant impact on the architectural and structural evolution of the rift in the study area during the Early Cretaceous and Paleogene periods.

Summary: The China-Pakistan Economic Corridor (CPEC) is a mega-construction project in Pakistan that requires exploration of new natural resources for aggregates. This study evaluates the optimal usage of Late Permian strata of Chhidru and Wargal Limestone for construction purposes using geotechnical, geochemical, and petrographic analyses. The Wargal Limestone proves to be a significant potential source for construction projects like CPEC, while the Chhidru Formation aggregates should be used with caution due to their vulnerability to alkali-aggregate reactions (AAR) and high silica content.

Summary: This work developed a numerical method to evaluate the required strength of 3D geosynthetic-reinforced soil structures with different water levels. It utilizes numerical simulations to obtain the distribution of pore-water pressures, avoiding the uncertainty of pore-water pressure coefficient. By discretizing a horn-like failure mechanism and using interpolation technique, the seepage forces acting on each element are determined. The required reinforcement is then determined through optimization based on work rate balance.

Summary: This study presents new data about sedimentary rocks from the Lengguru Fold and Thrust Belt (LFTB) in the Bird's Head of Papua. The Mawi Formation, previously believed to be pre-Tertiary, is now determined to be from the late Miocene to Pliocene. The study reveals two sedimentary facies successions: the delta-lacustrine succession (FS1) and the incised-valley fill succession (FS2).

Summary: The Karmostaj (Gach) and Siah Taq salt diapirs in the Zagros Mountains of Iran are world-class examples of salt extrusions, commonly referred to as salt glaciers. However, a field survey revealed that their glacier-like appearance is actually formed by thick, variegated, and deformed caprock, with only local salt content. Deformation within the caprock is primarily accommodated by shearing along gypsum-rich zones and pressure solution-precipitation creep of the lath-shaped gypsum grains.

Summary: This study used analogue modelling to analyze the effects of friction conditions, rheological structures, and compressional velocity on the deformation and evolution of fold-and-thrust belts. The results showed that the weak layer or low friction strength of the basement formed complex structural deformations. The friction strength ratio between the lateral and basement layers did not determine the structural style of a fold-and-thrust belt; instead, it was closely related to the construction of strata or rheological structures. The deformation of double detachment layers complicated the structural style of fold-and-thrust belts. The analogue modelling results were similar to the structural style of the Zagros fold-and-thrust belt (ZFTB), suggesting that deep and middle detachment layers controlled the current deformation of the ZFTB.

Summary: This article introduces the geological structures, history, and mineral deposits in the Vanna region of northern Norway. Studies show the presence of Paleoproterozoic basement rocks and various cover units that have undergone multiple deformation events. By studying the formation of ore deposits and geological processes, researchers aim to gain a better understanding of the region's geological evolution.

Summary: Submarine canyons play a crucial role in the formation and growth of continental margin depocentres. The formation of canyons is influenced by both ocean currents and erosion. The study on the eastern Niger Delta reveals that the formation and enlargement of canyons are related to extensional tectonic structures such as growth-faults. The morphology of the buried canyon system is shaped by various factors including sea-level change, ocean currents, and tectonic activity.

Summary: Two groups of depth-dependent temperatures were discovered in the front area of the Himalayan orogenic belt, with the first group measuring a peak temperature of 300-330°C in the Jurassic succession and the second group recording lower temperatures below 150°C. These temperature records highlight the thermal evolution of the crust and provide constraints for tectonic reconstruction and interpretation of crustal thickness.

Summary: Research indicates that bedding-parallel veins in the Vaca Muerta Formation primarily occur at facies boundaries and are influenced by major rheological discontinuities such as ashbeds, calcitic concretion boundaries, and organic-rich facies. Total organic carbon content also plays a role in the generation of these veins. Source rock maturity is correlated with the number and thickness of bedding-parallel veins, suggesting a link between hydrocarbon generation and the formation of these veins.

Summary: The thermal evolution of the Ukrainian Carpathians, an orogenic wedge, was analyzed using apatite fission-track and low-temperature thermochronology methods. The results showed that most of the apatite and zircon ages were reset, indicating incomplete dynamic equilibrium. The time-temperature paths of the nappes composing the wedge were determined through inverse modeling, revealing sequential accretion and exhumation. Sediments in the inner and outer parts of the Carpathian embayment originated from different sources, with limited sediment recycling from the wedge to the foredeep.

Summary: The study focuses on the influence of pre-existing structural elements and ductile layers on the final geometry and kinematics of fold and thrust belts resulting from tectonic inversion. Field data and seismic profiles were integrated to understand the current structure of the basin and determine the pre-shortening tectonic configuration. Results suggest that low angle normal faults and ductile layers play crucial roles in the development of thick and thin-skinned structures. The lateral extension of thin-skinned thrusts is fundamentally controlled by the areal extension of post-rift ductile strata.
