Summary: The asthenosphere beneath ancient and modern oceans is heterogeneous due to the recycling of old mantle domains and subducted oceanic crust and sediments. The mantle peridotites from the Kop Mountain ophiolite in the Neo-Tethys underwent ancient melt extraction and Jurassic melt metasomatism, representing recycled ancient sub-oceanic mantle domains. The Os isotopic distribution of Neo-Tethyan ophiolites is similar to global abyssal peridotites, indicating a highly heterogeneous asthenosphere with various mantle inputs.

Summary: The Eocene magmatic flare-up in NW Iran provides insights into the tectonic evolution of the region. The Ahar trachyandesites, formed during the Eocene, likely originated from an enriched mantle source due to the interaction between mantle wedge peridotite and oceanic slab-derived components during the subduction of the Neo-Tethys Oceanic slab along the Zagros segment. These rocks represent a record of crust-mantle interaction in an oceanic subduction channel.

Summary: The gold mineralization discovered in Northwest Iran occurred in the Late Paleozoic in an extensional tectonic regime, rather than above a subduction zone or collision zone as previously suggested. This mineralization was controlled by mantle-derived magmas from the asthenosphere, and hot magma injection contributed to the transportation and precipitation of gold within fractures.

Summary: This study examines relicts of granitic Gondwanan basement in the northwest of Central-East Iranian Microcontinent, incorporated into an ophiolitic melange. The findings suggest the presence of an Ordovician anatectic granite formed in a syn-collisional setting, with some metamorphic deformation signatures likely developed in the Devonian. The U-Pb zircon ages from this granite are similar to other Ordovician collision-related magmatic events in the CEIM.

Summary: The geochemical data and mineral phases of Tuting-Tidding Suture Zone ophiolites suggest that the peridotites were highly refractory and underwent high-temperature melt-rock interaction, while the associated mafic intrusives show characteristics of mid-oceanic ridge basalt formation, possibly within an active volcanic arc. The presence of hydrous minerals and low-temperature metamorphism in the ophiolites indicate later stage processes, either during a cool mature subduction zone or Himalayan Orogeny. The geochemical and petrogenetic aspects of the Tuting-Tidding Suture Zone ophiolites resemble other Neo-Tethyan ophiolites in the Indus-Tsangpo Suture Zone.

Summary: The Late Palaeozoic rock associations in Iran, particularly A-type igneous rocks, provide valuable information for reconstructing the evolutionary history of the Tethyan oceans, including their formation ages, magma activities, composition, and formation processes. Additionally, the magmatic rocks in Iran define a trend parallel to the ridge separating Neo-Tethys from the Iranian plate, indicating the separation of the Cimmerian terranes from northern Gondwana and their northward drift beginning in the Late Devonian to Early Carboniferous periods.

Summary: Ultramafic rocks in the Yarlung-Tsangpo ophiolites provide valuable information on the evolution of the Neo-Tethys Ocean and the heterogeneity of the sub-ridge mantle. The Xiugugabu ophiolite in the Yarlung-Tsangpo Suture Zone consists mainly of mantle components with minor crustal material. Petrological and geochemical studies indicate fractional melting from a depleted mantle source and post-melting melt-rock interactions. Highly radiogenic osmium isotopic compositions suggest the influence of percolating melts derived from mantle sources hybridized by ancient recycled crustal materials.

Summary: In temperate soils in Northern Italy, factors such as land use practices and soil types influence soil quality and SOM dynamics. Agricultural lands with organic material additions showed good soil quality and efficient use of microbial C, while reclaimed peaty soils were prone to degradation due to stress on soil microbial biomass. Conservative management practices in chestnuts reduced soil degradation risk. Evaluating soil parameters recommended by the FAO can help assess sustainable practices and soil quality.

Summary: This paper presents the results of map-to micro-scale structural studies of the western Durkan Complex in the Makran Accretionary Prism (SE Iran) to describe its structural and tectono-metamorphic evolution. The Durkan Complex consists of several tectonic units bordered by mainly NNW-striking thrusts. Three main deformation phases (D1, D2, and D3) are distinguished and likely occurred from the Late Cretaceous to the Miocene-Pliocene. The results shed light on the mechanism of accretion of seamount materials in the accretionary prisms, suggesting that seamount slope successions favour the localization and propagation of the basal decollement. This study further confirms the significant role of the physiography of the subducting plates in the tectonic evolution of the subduction complexes.

Summary: Graphitic carbon nitride (g-C3N4) has been widely used due to its excellent optical properties and physicochemical stability. The risk of g-C3N4 transport in the environment has been overlooked, but this study investigated its transport behavior in various media. The results showed that flow rate and ionic strength influenced the transport, and the presence of lead (Pb) affected the outflow of g-C3N4. The unique structure of g-C3N4 particles allowed them to deposit in certain media and act as carriers for Pb release.

Summary: Magmatic-hydrothermal systems play a crucial role in transporting materials and potentially affecting Earth's long-term environment. This study investigates the duration of prograde metamorphism induced by fluid infiltration and the amount of carbon released by skarn ore deposits. The findings reveal that skarn ore deposits can efficiently decarbonize CO2 at a high rate, surpassing volcanism in different tectonic settings. The CO2 flux of skarn deposits increases over time and reaches a maximum value at the J/K boundary, providing an important previously unquantified source of outgassing in the subduction zone.

Summary: This study analyzes the U-Pb-Hf-O isotopes of zircons in felsic granulite xenoliths from the Fuxin late Cretaceous basalts in the North China Craton to evaluate the role of magma underplating in modifying the Archean lower crust. The results show that long-lived magma underplating occurred beneath the Fuxin region during the Mesozoic, with underplated magmas originating from the lithospheric mantle and later from the depleted asthenospheric mantle. This study concludes that magma underplating not only provided heat for remelting, but also added exotic material and weakened the lower crust, leading to its destruction.

Summary: This study investigates two volcanic provinces in the western branch of the East African Rift and finds that the volcanic products show wide variability in chemical and mineralogical characteristics. Petrographic and geochemical analysis reveals enriched and heterogeneous sub-lithospheric mantle sources. The differences in isotopic features between the two volcanic provinces may indicate changes in the composition, mineralogy, and depth of melting in the lithospheric mantle source.
