Summary: Integrated sedimentological and petrographical analyses were used to reconstruct the paleoenvironment of the Mishan Formation (late Burdigalian-Serravallian) in the Dezful Embayment of the Zagros foreland basin. The results suggest the presence of a tide-dominated mixed siliciclastic-carbonate homoclinal ramp with the development of organic buildups in a tropical to subtropical warm water environment. These findings provide important insights into the Middle Miocene climate transition and the geological history of the Dezful Embayment.

Summary: In this study, a multidisciplinary approach was used to investigate the structural evolution of the Gachsaran Anticline. The results show that the thickness of the sedimentary cover decreases along the fault direction, and the eastern sector exhibits smaller folds and a tear fault that accommodates differential deformation. The study suggests that the mechanism and timing of deformation along pre-existing basement structures are important for hydrocarbon accumulation.

Summary: The timing of tectonic deformation in the Zagros foreland basin provides important information about the tectonic propagation process driven by the Arabia-Eurasia convergence. The integrated analyses of Miocene strata in the Dezful Embayment show that the transition from marine to non-marine occurred around 12.8 Ma, with cyclic marine transgressions and regressions driven by eustatic sea level fluctuations. Tectonic deformation caused by the Arabia-Eurasia collision had propagated to the Dezful Embayment by 11 Ma.

Summary: This study uses well data and earthquake focal mechanisms to determine the orientation and magnitude of present-day stresses in the Dezful Embayment in Iran's Zagros Fold and Thrust Belt. The results show a compressional stress state in the basement, while a normal/strike-slip regime exists in the shallow state of stress, possibly due to stress decoupling caused by salt layers.

Summary: The organic geochemistry of the Pabdeh Formation in northern Dezful Embayment, SW Iran, was studied using geochemical measurements. The results show that most of the analyzed samples have high total organic carbon (TOC) content and low volatile hydrocarbons (S1) content, indicating autogenic hydrocarbons. The Pabdeh Formation is classified as a fair to excellent source rock and the kerogen belongs to type II. Comparing with data from the southern parts of Dezful Embayment, differences in characteristics are found. The maturity of the Pabdeh samples is higher than determined by pyrolysis results.

Summary: This study analyzes two morpho-structural domes (Gavbast Dome: GD; Kooh Bedoo Dome: KBD) associated with growing anticlines in the Zagros Mountains. The uplift rates of the domes are around 0.1-0.4 mm/yr, and different fault patterns are observed. The high density of slope movements suggests that these domes play a significant role in the unroofing process.

Summary: The Zagros fold and thrust belt (ZFTB) in Iran serves as a natural laboratory for studying the kinematics of Arabia-Eurasia convergence/collision and has economic significance. This orogenic belt exhibits variations in stratigraphic makeup and structural style, as well as occurences of ophiolites along the Zagros suture line. The tectonostratigraphic attributes of the ZFTB are shaped by the irregular pre-collisional geometry at the northeastern edge of the Arabian Plate, as proposed in this paper.

Summary: This study investigates the structural decoupling in the Zagros fold-and-thrust belt in SW Iran, which is controlled by intermediate detachment horizons within the stratigraphic column. The effectiveness of these detachment horizons varies across the Zagros, influencing the folding style and the formation of structural traps. The study combines field mapping, seismic interpretation, and well data to analyze the complex structural style at six large-scale anticlines in the Central Zagros region. The results show that the efficiency of the detachment horizons is mainly controlled by the thickness of the formation, the salt content within it, and the amount of structural shortening.

Summary: Interpretation of seismic reflection profiles tied to well controls has allowed for assessing the stratigraphic and structural style of the Sulaiman Fold-Thrust Belt (SFTB), including the Zindapir Anticline and the Sulaiman Foredeep. The study found evidence of shallow marine shelfal deposits in the subsurface of the Sulaiman Foredeep, with prograding systems of the Paleocene-Eocene age and packages of divergent reflections fanning towards the west. This suggests accelerated subsidence likely linked to early stages of the SFTB orogeny during the Indian Plate-Afghan Block collision, forming an initial foreland basin to the east. Further deformation towards the east, as evidenced by Neogene faulted detachment folds in the ZA area, may indicate the influence of the Indian-Afghan collisional tectonics during the Oligocene-Miocene, with significant implications for petroleum exploration.

Summary: The Dezful Embayment Zone (DEZ) in the Zagros Mountains hosts predominant oil fields, where Geo-information Techniques (GiT) were used to study surface and subsurface deformation patterns forming traps for oil fields. Results revealed that activity along NW-SE orientated thrust faults led to fault related folding and accumulation of hydrocarbons. The complex transpression-transtensional model proposed for the region contrasts with the simpler structural pattern of the southern part of the DEZ.

Summary: The study revealed that the Nourooz-Hendijan-Izeh Fault is a segmented pre-existing basement fault that underwent reactivation in at least seven tectonic phases. Inversion tectonics affected hydrocarbon trap development in the Late Cretaceous and controlled their current conditions in the NW Persian Gulf and the southern Dezful Embayment. Mild to moderate inversion structures are considered preferred petroleum exploration targets in the region.

Summary: This study applies the anisotropy of magnetic susceptibility (AMS) technique to investigate volcanic materials in the Cadi basin of southern Pyrenees. The study aims to explore the limits of AMS technique in ancient volcanic materials that have undergone chemical alteration and complex tectonic evolution, and provide new insights into the deposition of volcanic materials in tectonically controlled sedimentary basins. The results show a close relationship between magnetic fabric and spatial distribution of mineral and grain components, primarily controlled by depositional processes with negligible impact from tectonic imprint. Therefore, magnetic lineation can be reliably used as a paleoflow indicator.

Summary: This study presents a geophysical-geochemical integrated model of the thermochemical structure of the lithosphere and uppermost mantle along a transect from the Northern Tyrrhenian Sea to the Pannonian Basin, crossing the northern Apennines, the Adriatic Sea, and the Dinarides fold-thrust belt. The objectives are to image crustal thickness variations and characterize the different mantle domains. The results show a more complex structure and slightly higher average crustal density of Adria compared to Tisza microplate. Two opposed subducting slabs beneath the Apennines and Dinarides have largely controlled the geodynamic evolution of the study region in the last 30 My.

Summary: The reinterpretation of the Organya Basin highlights the importance of Upper Triassic evaporites in the tectono-sedimentary evolution of the South-Central Pyrenees. The study integrates new field observations and subsurface data to create a restored cross-section that shows the template of the northern Iberian salt-rich rifted margin. The diapiric activity along this margin is divided into three stages: early salt mobilization in the Jurassic, main diapiric evolution from the late Jurassic to the middle Albian, and diapiric reactivation during basin inversion from the Campanian to the Miocene.

Summary: In this study, ambient seismic noise acquired in the Cerdanya Basin was used to evaluate the capability of different methodologies to map the geometry of a small-scale sedimentary basin. The results from various techniques, including autocorrelations, ambient noise Rayleigh wave tomography, HVSR, and band-pass-filtered ambient noise amplitude mapping, consistently showed that the deeper part of the basin is located in its central part, reaching depths of 600-700 m close to the Tet fault trace. The overall consistency between the results provides solid constraints to the basement depth estimation and helps improve the geological characterization of the Cerdanya Basin.

Summary: The petroleum resource assessment obtained from laboratory tests on old core samples tends to underestimate the in situ resources. This study investigates the hydrocarbon loss and restoration by comparing preserved and exposed core samples. It is found that previous studies have severely underestimated the in situ hydrocarbon potential due to factors such as sample crushing and crucible waiting. A new restoration model is proposed to compensate for these losses.

Summary: Quartz cement is an important authigenic mineral in the tight sandstones of the Shaximiao Formation in the Sichuan Basin. This study analyzed the silicon sources of the quartz cement using mineralogical, fluid inclusion, and geochemical data. The results showed that smectite alteration and dissolution of aluminosilicate minerals were the primary sources of silicon for quartz cementation. Contributions from volcanic material hydrolysis and pressure solution were relatively minor. The presence of chlorite films inhibited the development of quartz overgrowths and had minimal impact on reservoir quality.
