Summary: The Sierra Nevada de Santa Marta Massif in the Northern Andes provides insights into the structural evolution of the lower crust through a series of tectono-metamorphic events. These events, revealed through geological dating and geochemical analysis, have shaped the complex crustal section of the region, highlighting the tectonic processes that have occurred over millions of years.

Summary: A gypsum interlayer with 100 m thick was discovered in the Keban Metamorphics in southeast Turkey. The gypsum underwent hydrothermal alteration caused by late Cretaceous magmatic intrusions, resulting in dissolution, recrystallization, and the formation of secondary gypsum. The geochemical compositions of the gypsum indicate marine evaporite compositions.

Summary: The Mencue Batholith in western North Patagonian Massif consists of three major bodies: Mencue Granodiorite, Cura Lauquen Granite, and La Blancura Syenogranite. These bodies represent different episodes of magmatism, with ages ranging from 294 to 239 million years. The evolution of the batholith is characterized by a transition from solid-state deformed S-type granites to A-type granites, indicating changes in tectonic settings and magmatic processes over time.

Summary: The Vathi porphyry Cu-Au +/- Mo mineralization in the Serbo-Macedonian metallogenic province is associated with latite and quartz monzonite intrusions, resulting in various alteration styles and ore assemblages. Fluid inclusion data suggest a multi-stage mineralization history involving boiling hydrothermal fluids, moderately saline fluids, and later dilution processes.

Summary: This study provides new insights into the extensional events in northern Gondwana by studying the amphibolites in the Menderes Massif in Turkey. Based on zircon dating and geochemical analysis, the amphibolites likely originated in a within-plate tectonic setting, possibly triggered by northward subduction of the Paleotethys.

Summary: Research indicates that large amounts of high Ba-Sr magmatism in central Brazil's Tocantins Province are produced as a result of late accretion or decompression in the final stages of orogenic system evolution, leading to continental crustal growth. This type of magmatism is often associated with mega-shear zones and displays geochemical signatures indicating magmas derived from the melting of enriched lithospheric mantle.

Summary: This study presents new geological, structural, and microstructural data, as well as K-Ar geochronological data, to reconstruct the tectonometamorphic and magmatic history of the Cuesta de Rahue Basement Inlier in Patagonia, Argentina. The basement consists of a metamorphic complex deposited during the mid-Paleozoic and a metavolcano-sedimentary unit, with Late Carboniferous granitoids intrusion. The metamorphic complex underwent low-pressure metamorphism during the Devonian, while the metavolcano-sedimentary unit experienced deformation and metamorphism under higher temperatures, as determined by K-Ar and X-ray diffraction illite data from c. 232-199 Ma. This prolonged orogenic evolution also includes Late Carboniferous-Permian Gondwanide tectonomagmatic processes and Late Triassic deformation and metamorphism, followed by Mesozoic normal faulting and Andean deformation in the Miocene-Pliocene.

Summary: The bedrock geology of Finnmark, northern Norway, consists primarily of Precambrian and early Mid Palaeozoic rock complexes. Recent high-resolution aeromagnetic data have confirmed the continuation of Precambrian greenstone belts and granulite terranes beneath the Caledonian nappes. Different geophysical methods have indicated an increase in the depth of the Precambrian basement rocks from south to north in the study area.

Summary: The Campo Alegre-Corup ' a Basin in South Brazil developed in two stages, a synorogenic passive rift stage and a post-collisional caldera volcano stage. The Basin Stage exhibited bimodal volcanic rocks, with basaltic rocks derived from partial melting of an enriched lithospheric mantle source and silicic rocks resulting from fractional crystallization of the coeval basalts in the Moho. The Caldera Stage consisted mainly of alkaline trachytes and rhyolites, derived from higher degrees of partial melting of the same lithospheric mantle sources and associated with effusive basalts with Island Arc Basalt-like trace element signatures.

Summary: The study confirms ultra-high-pressure metamorphism in the Rhodope Metamorphic Complex in Bulgaria and determines the Variscan age of metamorphism through Lu-Hf dating of garnet-whole-rock. By analyzing eclogite samples from Belica and Gega, the research reveals the metamorphic processes and ages in these regions.

Summary: Paleogeographic reconstruction of Precambrian terranes reworked by Phanerozoic orogens, such as the Tibetan Plateau, reveals complex lithotectonic relations due to intracrustal reworking. Global and regional detrital zircon rare earth element (REE) databases show trends in LREE/HREE and Eu/Eu* that record the crustal evolution of the source and provide a new approach for paleogeographic reconstructions. By analyzing sedimentary and igneous rocks in the Lhasa terrane and detrital zircon samples from the northern margin of Gondwana, it is demonstrated that the Lhasa terrane had an African affinity in the Rodinia-Gondwana supercontinent cycles (ca. 1.4-0.4 Ga).

Summary: This study provides a detailed investigation of the Oulad Dlim Massif in southern Morocco, revealing different magmatic events from the Meso-Archean to the Cretaceous, as well as the influence of the Ediacaran-Cambrian extensional event and the Caledonian orogeny. It presents new insights into the geological history of the region, challenging previous ideas and contributing to the international scientific community.

Summary: This study investigates the Late Triassic to Jurassic plutons in the Intermontane terranes of Yukon, which record the end-on arc collision and onset of the northern Cordilleran orogen. The findings reveal that the early Jurassic plutons were associated with crustal thickening and subsequent exhumation, and the magmatic activity migrated southward with increasing crustal contributions. This differs from the coeval arc magmatism in British Columbia, showing a clear contrast in the magmatic and tectonic evolution between the two regions.

Summary: The study focuses on analyzing four lithotectonic units in the Balkans using detrital zircon U-Pb geochronology to understand their formation and origins. Through statistical comparison and multidimensional scaling, the Balkan terranes are compared with other terranes from the Eastern Alps to Iran, revealing their paleogeographic positions and significant dextral strike-slip displacements.
