Summary: Ophiolitic melange in the Eastern Hebei Complex of North China Craton consists of Zunhua and Shangying ophiolitic melanges. The Zunhua ophiolitic melange formed in a forearc supra-subduction zone (SSZ) setting and records a Neoarchean subduction initiation and arc-continent collision event. The Shangying ophiolitic melange formed at a mid-ocean ridge (MOR) and contains subducted masses mixed and exhumed in a subduction channel. Both melanges provide insights into the tectonic evolution of the late Neoarchean.

Summary: Newly discovered adakitic granite dikes in the Sumdo area of Tibet exhibit unique geochemical characteristics that suggest a subduction event involving the Sumdo Paleo-Tethys Ocean during the middle Permian. The rocks were derived from partial melting of subducted oceanic slab, with influences from slab-derived fluids and slight interaction with peridotite in the mantle wedge during ascent. Zircon U-Pb dating yielded ages of 269.1 +/- 4.1 and 266.4 +/- 2.0 Ma for the rocks.

Summary: The intrusion rocks in northwest Iran provide an ideal opportunity for studying geothermochronology and recording the tectonic evolution of the Tethys Ocean. Multiple magmatic events during the Late Carboniferous, mid-Cretaceous, and middle Eocene suggest subduction and ridge subduction processes. The results also highlight the significance of subduction and collision in post-magmatic cooling and exhumation processes.

Summary: The study of the Lubok Antu Melange reveals that its maximum depositional age is approximately 115 to 105 million years ago, sourced from a Mesozoic continental arc related to the Paleo-Pacific subduction, with possible contributions from West Borneo, the Malay Peninsula, and Sumatra. A change in source is recorded in the late Cretaceous, shifting from erosion of basement magmatic rocks of the Paleo-Pacific subduction-related arc to the Schwaner Mountains arc of SW Borneo. This suggests rapid uplift and exhumation of the Schwaner Mountains in the late Cretaceous, indicating potential geological changes in SW Borneo and the closure of the eastern Meso-Tethys during that time.

Summary: The magmatic record in the Jinshajiang-Ailaoshan suture zone in southwestern China indicates the presence of the Emeishan mantle plume and the late Permian Paleo-Tethyan oceanic subduction system. A study of late Permian quartz monzonites and granites in the Jinping area shows that these rocks exhibited A-type granite assemblages and geochemical characteristics, suggesting the occurrence of plume-subduction interaction during the late Permian in southwestern China.

Summary: The Buqingshan Complex, a part of the Muztagh-Buqingshan-Anemaqen ophiolitic melange zone, contains oceanic rocks that represent remnants of the Paleo-Tethys Ocean. These rocks exhibit characteristics of abyssal peridotites, normal mid-ocean ridge basalts (N-MORB), and oceanic island basalts (OIB). The geological, geochemical, and geochronological data suggest that the Late Palaeozoic N-MORB- and OIB-type rock assemblages are most likely fragments of mid-ocean ridge oceanic lithosphere and seamounts, respectively, representing the evolution stages of the Paleo-Tethys Ocean.

Summary: This study used phase equilibrium modeling to calculate the peak metamorphic conditions of Baqing eclogite to be 26.5 +/- 1 kbar and 730 +/- 60 degrees C, which confirms the previous calculation results. The eclogites of Baqing, Central Qiangtang metamorphic belt, and Changning-Menglian metamorphic belt show similar P-T paths, indicating similar heating and burial processes during Triassic subduction of the Shuanghu Paleo-Tethyan oceanic plate.

Summary: During the late Archaean, the assembly and stabilization of juvenile continental terranes contributed to the emergence and deposition of shallow-marine sedimentary sequences. This study examines the formation of the North Atlantic Craton in West Greenland and investigates the timing of continental assembly, stabilization, emergence, and maturation. The geochemical data from zircon and monazite extracted from the Storo quartzite, the oldest mature metasedimentary unit, provide insight into the geological processes involved. The findings contribute to our understanding of the complex processes that led to the development of enduring cratons.

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: New and compiled detrital zircon U-Pb ages from the southern Neoproterozoic-Cambrian Ribeira Belt, SE Brazil, indicate a distinct affinity of the Embu Terrane compared to the Apial and Sao Roque terranes, supporting an allochthonous interpretation. The detrital zircon age spectra reveal a greater affinity of the Embu Terrane with SW Laurentia basins, suggesting its origin through collision with the Ribeira Belt during the early Neoproterozoic.

Summary: In the Cretaceous extensional system of South China, lithospheric extension is mainly accommodated by localized normal faulting and distributed ductile stretching in the lower crust, followed by localized crustal necking and Moho uplift. These crustal and mantle features are kinematically linked, with lower-crustal stretching compensating for upper-crustal thinning and mantle shear zones affecting localized Moho uplift and crustal necking. The extension mechanism varies laterally from magma-poor to magma-rich conditions, resulting in changes in crustal melting, decoupling, and lithospheric mantle configuration.

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: Rocks with adakitic affinities in continental collision zones provide important information about crustal thickening. Traditional understanding suggests that residual garnet during partial melting of the lower crust is responsible for heavy rare earth element and Y depletion in these rocks. However, this study finds that magmatic garnet is rarely observed and amphibole is proposed as an abundant phase in the lower arc crust. The authors report the isotopic compositions of adakitic intrusions, suggesting an amphibolite source and an existing, older crustal foundation. Rating: 8/10.

Summary: Shear zones in the Borborema Province of northeastern Brazil are efficient conduits for mineralizing fluids. The emerald occurrences in this region are associated with strike-slip deformation zones formed during the Neoproterozoic-Cambrian Brasiliano orogeny. The Portalegre shear zone, where the Paraná deposit is located, exhibits distinct aeromagnetic anomalies and mylonitic gneisses and schists with vertical foliation and horizontal mineral stretching lineation. The emerald mineralization is found in phlogopite and actinolite-phlogopite schists and is related to the interaction between Be-bearing pegmatite dykes and amphibolite lenses during strike-slip motion on the shear zone.

Summary: This study explores the impact of hydroclimate on landscape erosion using sedimentary records from the late Permian. The findings reveal a negative carbon isotope excursion and a decrease in weathering intensity in the middle Wuchiapingian period. The results suggest a correlation between increased denudation rates and a decrease in paleosalinity, possibly due to higher precipitation.
