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: During the Laramide orogeny in southern Arizona, granitic rocks related to crustal melting were emplaced into regions of thickened crust. Through isotopic and geochemical analyses, it was determined that these rocks originated from intermediate-mafic (meta)igneous rocks at deep crustal levels. The early Paleogene Relleno suite in the Pinaleno Mountains further strengthens the connection between crustal melting and regions of thickened crust associated with the Sevier and Laramide orogenies.

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: This article investigates the high-pressure and high-temperature metamorphism during the Mid-Devonian period in the Variscan Orogeny, focusing on the geological characteristics of the Marianske Lazne Complex (MLC). The unique position of MLC at the base of its original upper plate is highlighted. The study reveals that both MLC and the upper plate developed above a relatively unaltered Neoproterozoic lithospheric mantle, which is important for reconstructing the original architecture of the Variscan terranes.

Summary: Pre-Cryogenian crystalline rocks occur only in the eastern part of the Arabian Shield, around Jabal Muhayil in the Khida sub-terrane. These rocks have been studied and their origins and ages have been determined. The presence of different sized rock masses with inherited zircon up to ca. 2.5 Ga and Neoarchean precursors has been detected. Other rocks only have Neoarchean precursors. These findings suggest that these rocks were influenced by Neoarchean continental crust.

Summary: The palaeoecology of the Xenacanthiformes has been a topic of debate, with conflicting opinions on their habitat and migratory behaviors. Recent studies have challenged the hypothesis of a full freshwater ecology, instead suggesting euryhaline ecology and migratory behavior based on histology. Two ambiguous localities in France, Buxie`res-les-Mines and the Muse oil-shale bed, have been interpreted as freshwater settings but with doubts about marine influences. Stable isotope analysis of vertebrate faunas from these localities suggests that Buxie`res-les-Mines was a large and deep freshwater lake, similar to Lake Matano in Indonesia, while the Muse OSB was a shallow tropical lake with drying events, similar to Lake Punta Laguna in Amazonia or Lake Tanganyika in Africa.

Summary: This paper presents a study on the Maoling gold deposit, revealing its ore-forming mechanism and genesis, including the composition of magmatic water and meteoric water, the characteristics of fluid inclusions, and the isotopic characteristics of sulfur, hydrogen, oxygen, and lead. The results show that fluid boiling was the critical factor controlling the mineralization at Maoling, and the ore-forming materials mainly originated from the host rocks and magma.

Summary: This study investigates the causes of increased organic carbon burial in lacustrine settings during the Early Aptian period in western Liaoning Province, China. It finds that volcanic activity in north China was the main factor driving enhanced lacustrine carbon burial, leading to the formation of organic-rich layers distinct from global marine organic matter burial processes.

Summary: A new model for a Tonian active continental margin in the Neoproterozoic western foreland of the Delhi Fold Belt of NW India is introduced in this study, indicating a transition from continental crust into an active arc setting before the emplacement of the volcano-plutonic Malani Igneous Suite. The Erinpura Granites in a large area west of the Delhi Fold Belt are S-type, whereas the granites, granodiorites, and gabbros in the westernmost basement outcrops are I-type and show positive Nd ratios. The integration of data from East Pakistan and East Oman establishes an evolutionary model for a Tonian active continent margin, suggesting 130 Myr of ongoing subduction along the continental margin from 900 to 770 Ma.

Summary: The nickel-cobalt mineralizations in Lubietova-Kolba and Cierna Lehota in the Central Western Carpathians are dated using rhenium-osmium isotope geochemistry, indicating a relationship with an extensional tectonic regime and hydrothermal fluid flow associated with the opening of the Meliata ocean in the Middle Triassic.

Summary: The study examined previously unrecognized mafic and felsic plutonic rocks, as well as a possible upper-crustal equivalent, in the Bohemian Massif. The rocks exhibited evidence of active margin magmatism and Mid-Devonian magmatism, with a three-stage geodynamic model proposed to explain their formation. The magmatic rocks recorded a Mid-Devonian magmatic arc related to the subduction wedge beneath the upper plate.

Summary: New geochronological data for the Karasjok Greenstone Belt in northwestern Fennoscandia shows that its age ranges from 2.47 to 1.96 billion years ago. This study provides important insights into the geological evolution of the region during the early Paleoproterozoic era.

Summary: New geochronological data reveals the age of the Karasjok Greenstone Belt to be between 2.47 and 1.96 billion years. It consists of volcano-sedimentary units deposited on crystalline basement rocks. The study also identified various tectonic events related to magmatism, rifting, and supercontinent breakup. Carbon isotope analysis indicates isotopic variations in carbonate sediments from different formations within the belt.

Summary: Inverted passive continental margins provide a comprehensive understanding of fluid circulation in the continental crust during orogens. This study uses U-Pb geochronology and Pb-Sr-O-H isotope geochemistry to trace hydration events in the continental crust of the inverted Adriatic passive continental margin. The results reveal multiple hydration events with different fluid sources and pathways.
