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: 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: 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: The LeMay Group accretionary complex in Alexander Island consists of deformed turbidites and thrust slices of ocean floor basalts. The age and provenance of this complex are uncertain, ranging from Carboniferous to Cretaceous. The accretion history is poorly established, but our geochronology and geochemistry analysis suggests its deposition, provenance, and accretion occurred during the Permian to mid-Triassic, mid-Cretaceous, and Early Jurassic respectively.

Summary: The Borborema Province in NE Brazil is part of a large Neoproterozoic orogenic system related to the assembly of West Gondwana. The evolution of this province is contentious due to multiple overprinted events. A compilation of geological, isotopic, and geophysical data supports a terrane accretion model for the Transversal subprovince within the Borborema Province, revealing different terranes with varied ages and nature as evidence of accretion.

Summary: The study focuses on the zircon record of high-grade gneiss terrains, particularly on metamorphosed mafic rocks and their in situ leucosomes. By analyzing the metamorphic ages of mafic migmatites in the central region of the Lewisian complex, it is found that the age clusters are similar across disparate terrane blocks, suggesting a common pre-metamorphic history and questioning the validity of the terrane model. Mafic lithologies provide valuable insights into the complex evolution of metamorphic complexes and offer additional context for understanding Earth's geodynamic evolution.

Summary: Detrital geochronology, combined with zircon Hf isotopes, has been used to study the sedimentary sources and evolutionary history of the Western Qinling-Songpan tectonic junction in central China. A dataset of 20,640 zircon U-Pb ages and 1,636 zircons with Hf isotopic data from 281 sandstone samples was obtained. The compiled data can be used in various research fields, such as provenance analysis, climate change, and paleogeographic reconstruction.

Summary: This study provides detailed insights into the tectonic and evolutionary history of the Eastern Cordillera in Peru, with important evidence related to the accretion of the Arequipa Terrane. It sheds light on the early Paleozoic tectonic history of the region and presents a new tectonic model explaining the late Neoproterozoic to early Cambrian collision events.

Summary: Understanding the timing of the proximity between Archean and Proterozoic terranes is the aim of this study, which investigated the contact zone between the southern Motloutse Complex and the northern Mahalapye Complex in eastern Botswana. The study suggests that these two terranes may have come together at around c.2.04 Ga, with the emplacement of a syntectonic Mokgware granodiorite. The results highlight the factors important for defining contact zones between terranes with distinct geologic histories.

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.

Summary: The Ossa-Morena Zone is a Gondwana-related terrane composed mainly of Cambrian rocks. U-Pb dating of zircon grains from 15 samples revealed the absence of a significant Stenian-early Tonian population in the Cambrian Ossa-Morena rocks, in contrast to the results from middle Ordovician-Lower Devonian rocks in the same area. This suggests a change in the paleogeographic/paleotectonic evolution of the Ossa-Morena Zone during the late Ediacaran-early Ordovician period, possibly involving an eastward displacement and a reorganization of drainage systems.

Summary: The Yehe-Shigna ophiolite massif is part of the Belsk-Dugda ophiolite belt, located in the Tuva-Mongolian microcontinent in the Central Asian orogenic belt. The study findings suggest that the massif was formed around 810-750 million years ago in the back-arc basin of the Shishkhid intraoceanic island arc. The research also indicates the presence of gold-telluride deposits in the ophiolite thrust zones, which may be found in other similar ophiolites derived from the Gondwana supercontinent.

Summary: This article discusses the complex evolution of the Gondwana along the flank of the West African Craton and the geological activities that occurred in this region. The geochemistry of sedimentary and igneous rocks can provide insights into the evolutionary history of their sources. The study also reveals the intricate relationship between magmatic activity and tectonic deposition, which has implications for future paleogeographic reconstructions.

Summary: The study investigates garnet-orthopyroxene-spinel-cordierite-plagioclase-K-feldspar-quartz bearing granulites from the southern margin of the Madurai Block in India. Results from petrology, mineral chemistry, geothermobarometry, and U-Pb geochronology provide insights into the formation and evolution of these rocks, revealing pressure-temperature conditions at different stages and the geological ages of zircon and monazite in the samples. The granulites experienced prograde, peak, and retrograde evolution, recording geological events from Paleoproterozoic to Neoproterozoic times.
