Summary: This study reconstructs the ages and tectonic attributes of ophiolites in the Bangong-Nujiang suture zone, Tibetan Plateau, to understand the ancient ocean tectonic evolution. The results indicate that the ophiolites formed during the Middle-Late Jurassic period and represent a mature intra-oceanic arc and fore-arc basalts. These findings provide important insights into the tectonic evolution of the Meso-Tethys Ocean during the Middle-Late Jurassic.

Summary: The Qimantagh back arc basin underwent complex tectonic evolution processes, including opening, subduction, and closure. The results of this study indicate that the closure of the back arc basin led to a crustal thickening event around 420-410 million years ago.

Summary: This paper reconstructs ancient mantle-derived igneous rocks that once existed on the Paleozoic Pacific-type convergent margins through studying the greywacke sandstones from Kazakhstan, revealing the influence of southwards subduction erosion on young arc islands. The greywacke sandstones in Kazakhstan were primarily formed by mafic to andesitic igneous protoliths derived from juvenile mantle sources, providing significant value in academic research.

Summary: During the Late Cretaceous in the Eastern Mediterranean, the closure of the northern branch of the southern Neotethys was caused by multiple northward subductions. This resulted in the formation of the Baskil continental arc and the Yuksekova Complex, representing different tectonic settings and sources.

Summary: This paper presents U-Pb detrital zircon ages, geochemical data, and Nd-Hf isotope data from sandstones of eastern Kazakhstan, suggesting a juvenile character of igneous rocks in the provenance and a derivation from one or more intra-oceanic arcs. The data from eastern Kazakhstan support the existence of an extended Pacific-type subduction system in the western Paleo-Asian Ocean during the Devonian-early Carboniferous time.

Summary: Lamprophyre is an important probe for understanding the evolution of the lithosphere. This study focuses on the Taolin lamprophyre in the Sulu Orogenic Belt and uses zircon U-Pb dating to determine its age. The lamprophyre is characterized by specific chemical compositions and isotopic compositions, suggesting a complex petrogenesis involving subducted crustal materials and metasomatic processes. The geodynamic trigger for the formation of the lamprophyre is proposed to be related to lithospheric thinning and asthenospheric upwelling beneath the North China Craton.

Summary: New U-Pb geochronology findings from Sabah, Malaysia suggest that mafic-ultramafic rocks in the region were not ophiolitic and did not form during the Jurassic-Cretaceous period, as previously believed, but rather originated from a magmatic event in the Miocene. These rocks show evidence of both mantle-derived and crustal components, with the involvement of a crustal component possibly linked to the evolving Miocene oceanic basin in the area.

Summary: This study presents seismic reflection profiles and geological, paleontological, and geochemical data from borehole cores in the Songliao Basin, China, to determine the timing, provenance, and tectonic background of the Linxi Formation. The data provides evidence for the closure of the eastern Paleo-Asian Ocean and associated orogenesis.

Summary: The GTS granites in the Xing'an Block have been studied for their geochronological and geochemical characteristics, providing insights into the subduction processes of the Palaeo-Asian Ocean in the eastern Central Asian Orogenic Belt. The results indicate two stages of emplacement with different geochemical signatures, suggesting a change from a subduction setting in the Early Carboniferous to an extension setting in the Late Carboniferous, likely caused by the subduction slab break-off of the Palaeo-Asian Ocean.

Summary: The study of the Xiangjiananshan granitic plutons in the East Kunlun Orogenic Belt of the northern Tibetan Plateau reveals that these rocks were formed by partial melting and mixing of the lower crust, influenced by the subduction of the Buqingshan-A'nyemaqing Ocean.

Summary: This study presents new geochronological and compositional data for alkaline-mafic igneous rocks from the Goryachegorsk area in Siberia, Russia, suggesting a complex magmatic history with mixing of various sources. The geochemical similarities between different age alkaline magmatism in the region provide insights into mantle plume-lithosphere interactions over a span of approximately 250 million years.

Summary: The Early Carboniferous volcanic and intrusive rocks found in the Mayile area of West Junggar, northwestern China, are typical subduction-zone island-arc magma, characterized by enrichment in light rare-earth elements and large-ion lithophile elements, and depletion in heavy rare-earth elements and high-field-strength elements. This suggests that extensive intra-oceanic arc magmatism occurred in West Junggar during the Early Carboniferous period.

Summary: The northern Alxa orogenic belt is an important link connecting the eastern and western segments of the Central Asian Orogenic Belt, providing valuable insights into its tectonic evolution. This study, through detailed geochronological, geochemical, and isotopic analyses, reveals that the northern Alxa orogenic belt was in a post-collisional extensional setting during the Middle to Late Permian.

Summary: The Agardagh Tes-Chem complex (ATCC) in Tuva, Central Asia, contains a rare mafic to ultramafic crust-mantle fragment that developed within an intra-oceanic island arc system. Residual mantle rocks are highly refractory, while ultramafic cumulate rocks show distinct characteristics.

Summary: This paper presents new data on the elemental and isotopic composition of basalts and the ages of zircons from the Subashi ophiolite in the West Kunlun Orogenic Belt (W-KOB). The results suggest that the Subashi ophiolite originated from a depleted spinel lherzolite mantle source in a mid-ocean ridge setting. The ages of the zircons indicate the existence of the Proto-Tethys ocean basin during the Early Paleozoic.

Summary: The crust of Iran and Anatolia was mainly formed during the Cadomian crust-forming event from ca 620 Ma to ca 500 Ma, as a result of subduction of oceanic lithosphere beneath northern Gondwana. Cadomian magmatism included calc-alkaline igneous rocks of arc affinity in the main arc and alkalic igneous rocks in a back-arc setting, associated with sedimentary rocks, with basaltic magmas as the main input.

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.

Summary: The study on gully erosion in the East African Rift Valley of Kenya reveals that human activities and rainstorms are the main factors causing erosion. Gully erosion poses a serious threat to the ecological environment, particularly the man-made and fissure-induced gullies that should be further investigated.
