Summary: The Pan-African belts of Malawi contain a rich endowment of gem-bearing pegmatites, formed during different geological events. Some pegmatites are associated with the intra-continental rifting episode and the collision of Western and Eastern Gondwana, while most pegmatites formed during the collision of the northern and southern Gondwana cratonic entities. These pegmatites contain various gemstone species and show varying degrees of crustal affinity.

Summary: Research in the Boss`ost dome of the Pyrenean Axial Zone has shown that mineralization formation is controlled by Variscan tectonics and associated with a major Variscan remobilization event. The poly-magmatic and metamorphic events in the Pyrenean Axial Zone have unclear relationships with the mineralization.

Summary: Tectonic fluid expulsion in permeable foreland basin sequences has been examined, and it has been discovered that fluids migrate through low-permeability successions. U-Pb data from the Hamersley region in Australia indicate that fluids expelled during tectonic compression migrated through older shales by fracture permeability and enhanced diffusion. The timing of veining was not random, but coincided with major orogenic events, linking fluid overpressure and hydraulic fracturing to the expulsion of heated orogenic fluids. These findings provide insight into fluid flow in geological processes.

Summary: This study presents new geochemical and isotopic data for the mafic suite of the Buem structural unit in Ghana, providing insights into its origin, geodynamic setting, relationship to the Pharusian suture zone, and significance in the Dahomeyide belt. The results suggest that the Buem structural unit represents the remnant of the Pharusian oceanic crust, formed during the breakup of Rodinia, and corresponds to a continental margin-type ophiolite.

Summary: By analyzing the U-Pb ages of detrital monazite from Cambrian sedimentary rocks, we suggest that South China was located outboard of northeastern India. The detrital monazite ages indicate input from earliest Cambrian metapelites and provide tighter constraints on the paleogeography of South China compared to detrital zircon data alone.

Summary: This study investigates the Ross Orogenic Belt in the Transantarctic Mountains of Antarctica. By analyzing the geochemical and geochronological data of the North Victoria Land Granite Harbour Intrusive complex, the impact of early Paleozoic magmatism on continental crust growth through accretionary orogenesis is revealed. The syenite shows characteristics of island-arc granite and was emplaced at approximately 471.8-477.3 Ma, resulting from the partial melting of the lithospheric mantle enriched with subduction slab fluids and subcontinental lithosphere. A tectonic-magmatic model involving alternating phases of extension and contraction in the overriding plate is proposed. The study concludes that the (post-orogenic) magmatism occurred during extension in the overriding plate at around 478-471 Ma.

Summary: Detrital zircons from two major rift basins in the East African Rift System are analyzed to understand sediment provenance, landscape dynamics, and the volcanic evolution of the rift system. The results show that the sediments mainly come from silicic volcanic rocks, and the zircon ages correspond to the timing of rift activity. The discrepancy between (U-Th)/He and U/Pb ages of zircons may be related to late volcanic and/or hydrothermal activity.

Summary: In this study, in-situ monazite U-Th-Pb geochronology was used to investigate the fluid flow events in shale samples from the Sichuan Basin. Two fluid flow events at approximately 450 Ma and 263 Ma were identified, with the former related to subduction in the Proto-Pacific Ocean and the latter associated with the emplacement of the Emeishan large igneous province. The findings have significant implications for understanding the complex histories of fluid flow, oil charging, and gas generation in petroliferous basins.

Summary: The Lower Eocene strata in the southern Canadian Cordillera hinterland were deposited in multiple compartmentalized basins in alluvial fan, fluvial, lacustrine, and paludal environments. Detrital zircons with ages around 50 Ma are interpreted to be derived from volcanic activity, while another population with ages between 145 and 200 Ma indicates different sediment sources and paleodrainages within the southern Canadian Cordillera.

Summary: Chronic kidney disease is a global public health issue, with African countries disproportionately affected. The CKD-Africa Collaboration has gathered data from 39 studies in 12 African countries, with a focus on sub-Saharan Africa. Challenges in building the network were faced, managed, and showed the benefits of collaboration for Africa. Lessons learned can be applied to public health research in LMICs.

Summary: The study focuses on detrital zircon from the black sand of the Rhone River delta in southern France, which provides important insights into the major episodes of European magmatism. The results show that the black sand samples represent magmatic events at 0.55 Ga (Cadomian), 0.45 Ga (Cenerian), and 0.31 Ga (Variscan). The Hf isotopes in the zircon suggest the involvement of continuous crustal reworking during European magmatic episodes. However, the oxygen isotope analysis indicates the presence of a significant sedimentary component in the genesis of European granitoids. The study concludes that the prevalent Hf-T-DM ages obtained are mixed and do not confirm the reworking of Mesoproterozoic crust in the region.

Summary: This paper presents new U-Pb geochronological data on granitoids from the Moroccan Meseta Variscan belt. The results show a peak of magmatic activity at 335.2 +/- 0.8 Ma in the Western Meseta and early Visean magmatic activity in the Eastern Meseta. The study also suggests a possible relationship between the magmatic activity and the tectonic events in Northwest Africa. Evaluation: 8 points.

Summary: This article reviews the geology and tectonic models of the Sveconorwegian orogeny, proposing an updated geodynamic scenario of a large continental collision starting at around 1065 Ma. It discusses the formation of an orogenic plateau, extensive magmatism, and metamorphic events, pointing towards a shallow asthenosphere under the crust and a retreating delamination of the dense sub-continental lithospheric mantle. The orogenic plateau eventually collapsed around 930 Ma, with extensive erosion removing overburden.

Summary: The combination of structural data and 40Ar/39Ar geochronology has provided insights into the deformation and cooling history of the Kongsberg lithotectonic unit and its boundary zone with the Telemark lithotectonic unit in southern Norway. The study reveals that the Kongsberg unit experienced deformation and cooling between 1090-1070 Ma, with a resetting event around 1000 Ma due to sinistral strike-slip deformation. Neoproterozoic shearing caused the exhumation and juxtaposition of Telemark rocks against the previously cooled Kongsberg gneisses, with shearing and cooling occurring between 940-900 Ma. Furthermore, the study suggests localized resetting during the Silurian period (420 +/- 11 Ma) and intrusion of an Oslo Rift granite during the Permian period (288 +/- 1 Ma).
