Summary: The study describes two new species of palaeomantids from the Early Permian Niedermoschel black shale in the SaarNahe Basin in Germany, named Delopterinus alsenzensis sp. nov. and Delopterum novokshonovi sp. nov. A third Palaeomanteidae has also been identified but not named. These small insects were found to be widespread in the northern part of Pangea during the Permian period.

Summary: The Saar-Nahe Basin is one of the largest intra-continental basins of the European Variscides, filled with up to 6500 m thick volcano-sedimentary rocks representing 40 million years of basin evolution. The first high-precision U-Pb CA-ID-TIMS age of a previously undated ash tuff layer of the Altenglan Formation yielded a result of 298.7 +/- 0.4 Ma. Comparative analyses of zircons from the same layer confirmed this age, supporting a Pennsylvanian-Permian boundary within the Altenglan Formation and suggesting an earliest Asselian age for a globally important fossil tetrapod lagerstaette.

Summary: The study area in the Punjab Territory of Pakistan was analyzed using 2D seismic and well log data to interpret the subsurface structure and reservoir characteristics of the Kabirwala area Tola (01) well. Formation evaluation for hydrocarbon potential and petrophysical analysis were conducted to identify possible hydrocarbon-bearing zones, with the presence of the Tola-01 well providing confirmation for potential hydrocarbon entrapment in the high zone of interest.

Summary: Holographic display offers natural 3D display effect, but the scarcity of 3D content limits its application. To address this issue, a 2D to 3D rendering approach is proposed to enrich the content of holographic display.

Summary: Through studying the seismic site response in the Kutch basin, significant amplification was observed at the basin center and the region between the center and the edge, with the frequency content of the surface motion shifting from a narrow to a broad spectrum from the edge towards the basin center.

Summary: Frequent wildfires in Pennsylvanian ecosystems were possibly due to high atmospheric oxygen levels. Evidence of wildfires during the Upper Pennsylvanian Heusweiler Formation deposition was found in the Saar-Nahe Basin in SW-Germany, suggesting that some fires occurred in ecosystems inhabited by Cordaites. Charcoal fragments with fungal decay traces indicate wildfires consuming litter or dead trees, providing insight into the fire dynamics during that period.

Summary: A new genus and species of archaeorthopteran, Penanoptera manseri, was discovered in the Early Permian Niedermoschel black shale in Germany, marking the fifth taxon of stem-Orthoptera from this stratum. This finding highlights the significance of this insect assemblage in the context of Early Permian insect evolution.

Summary: Using receiver function analysis, new seismic models for the Permian Basin region were derived, revealing that sedimentary velocity discontinuities are shallower in sedimentary basins, with Moho depths ranging from 36 km to 46 km. Variations in crustal Vp/Vs ratios among subregions suggest differences in geological structures and rock compositions.

Summary: Modern petroleum exploration uses seismic data to study paleo-shorelines and tectonic movements during past glacials. The study focuses on the western shores of the Levant and identifies a pinchout isobath that records a significant drop in sea level during the late Quaternary glacials. The study suggests that this isobath is closely related to the shoreline of one of the last glacial maxima and provides insights into tectonic activity and glacial eustatic levels in the region.

Summary: The study focused on the subsurface geology of Bannu Basin in western Indus foreland Pakistan, utilizing regional seismic profiles and deep exploratory wells data. The results indicate a northwest-dipping formation trend, with potential hydrocarbon entrapment structures identified. Well correlations show significant lateral and vertical variations, with well failures attributed to poor data quality and mechanical issues. Reservoir characterization using statistical rock physics and petrophysics can provide further insights into hydrocarbon exploration efforts.

Summary: This study proposes a Multi-track and Multi-temporal 2-D (MTMT2-D) method to decompose the 2-D deformations of subsequent earthquakes by fusing multitrack and multitemporal interferograms. The results show that the decomposed deformations can better constrain the fault geometry and reveal a domino-like triggering rupture process for the earthquake sequence.

Summary: We report a fossil forewing of an archaeorthopteran insect from the Early Permian period. It belongs to a new genus and species, Saarelcana stapsi, and represents the oldest known record of the Elcanoidea group. This discovery adds to the already high diversity of archaeorthopterans in the Pennsylvanian and Permian periods.

Summary: In this paper, the applicability of the pre-stack depth migration method is tested using a deep seismic reflection dataset collected from the Bohai Bay Basin. By improving the signal-to-noise ratio of the prestack gathers and building an accurate velocity model, a high-quality pre-stack depth migration profile is obtained. This profile provides a higher-resolution subsurface image with accurate depth information, revealing geological structures and crust-mantle interaction in the study area.

Summary: An integrated approach combining petrophysical analysis, seismic data interpretation, seismic attributes analysis, lithology, mineralogy identification, and Gassmann fluid substitution was used to identify potential leads by providing information about the subsurface structure, fluid type, and physical properties of rocks. Structural interpretation using seismic data revealed an extensional regime with horst and graben structures in the study area, with two negative flower structures cutting across the Cretaceous deposits. Well data interpretation identified four possible reservoir zones in the Sawan-01 well and two zones in the Judge-01 well, with the main lithology being sandstone with thin beds of shale in the Lower Goru Formation.
