Summary: The North China Craton has undergone large-scale lithospheric removal and magmatism since the Mesozoic, resulting in changes in physical and chemical characteristics of the lithospheric mantle. The emplacement mechanisms of plutons in different stages were controlled by regional extension, indicating a strain-increasing tendency. Extensional tectonics in the eastern NCC represent interactions between the Mongol-Okhotsk belt, Paleo-Pacific plate, and eastern Eurasian continent.

Summary: The Canadian Superior Province is a key area for studying Late Archean geological processes and mechanisms of rock growth, with a proto-cratonic core and several juvenile terranes. This study of a pluton in northeastern Quebec reveals a two-stage assembly process through analysis of rock structures and tectonic evolution.

Summary: Core samples from Panasqueira tungsten deposit in Portugal were analyzed chemically and petrographically. The results reveal a complex granite body consisting of a cupola of porphyritic granite, a stock of greisenized leucogranite, and quartz veins rich in wolframite. The deposit formed through three stages of intrusion, greisenization, and hydraulic fracturing, indicating the involvement of hydrothermal fluids from deep parts of the granite body.

Summary: The study reconstructs the evolution of the Torrelapaja Subbasin in the Cameros Basin, Spain, during the Late Jurassic to Early Cretaceous, identifying three synrift sequences controlled by major and minor faults. Sedimentation occurred in alluvial fan systems, carbonate environments, and coastal flats. The first marine incursion in the Early Cretaceous is marked by the SS-3 unit.

Summary: The Tyrnyauz deposit is the largest W skarn deposit in Russia and the FSU, with unique characteristics such as large mineralized skarn zones and overprinting wider systems of post-skarn quartz-garnetpyroxene. This deposit is associated with at least two separate igneous suites, suggesting a complex geological history. The superposition of different igneous suites and related mineralization styles may have played a key role in the formation of this giant metal endowment.

Summary: By studying the Miocene syn-tectonic Porto Azzurro pluton on Elba, Italy, researchers found that localized ductile deformation can affect a granitic intrusion even after it enters the brittle domain in a fast exhuming extensional regime. This challenges the general assumption that exhumation and cooling of upper crustal plutons always lead to an abrupt transition from crystallization to faulting.

Summary: In response to craton destruction, the North China Craton underwent Early Cretaceous extensional tectonics, accompanied by plutonism, volcanism, and extensional structures. Two plutons from the early stage of the Early Cretaceous were studied, showing they intruded in a weak extension regime before the peak of magma flare-up and large-scale extension in the NCC. The Early Cretaceous extension in NCC was divided into early-stage weak extension during 130-127 Ma and late-stage intensive extension during 127-110 Ma, with the large-scale extension initiated after 127 Ma.

Summary: The Bokan Mountain granitic complex in southernmost Alaska is a circular body composed of peralkaline granites that intruded Paleozoic granitoids. It hosts a high-grade uranium-thorium deposit with structurally controlled rare metal mineralization. The deposit mainly consists of desilicified and albitized granitic rocks containing uranothorite and uraninite.

Summary: The Boein-Miandasht Complex in western Iran is composed of various rocks formed in the Late Jurassic, displaying typical characteristics of ferroan A-type granites. The formation of these rocks may be attributed to extensional tectonic regime and partial melting of the lower crust due to the injection of hot mafic magmas within the crust.

Summary: This study reconstructs the structural evolution and sedimentation of the southern Liaodong Peninsula using geological mapping, borehole data, field structural studies, and zircon geochronology. The research reveals that the onset of paleo-Pacific plate subduction along the eastern Asian margin occurred in the Late Jurassic to Early Cretaceous. The study suggests that the subduction margin and subsequent synconvergent extension were the result of slab flattening and rollback during episodic subduction of the paleo-Pacific plate.

Summary: The structure of sand plays a vital role in its mechanical behaviors and liquefaction resistance. Current optical techniques do not provide ideal solutions for fabric visualization. This study introduces the anisotropy of magnetic susceptibility (AMS) as a convenient and efficient way to evaluate liquefaction in clean sand, and its feasibility is verified through laboratory tests and in situ observation.

Summary: Li-F granites from the Kester deposit in Russia are associated with a rare-metal complex of accessory minerals including montebrasite, columbite-(Mn), columbite-(Fe), tantalite-(Mn), Ta-bearing cassiterite, U-bearing microlite, W-bearing ixiolite, niobian ferberite, U-Hf-rich zircon, and Ta-bearing rutile. The discovery of tungsten-bearing wodginite confirms the presence of tungsten and tungsten-bearing accessory minerals in Li-F granites in the Russian Far East, and indicates the presence of rare-metal tin-tantalum-bearing granites and pegmatites.

Summary: The Xintianling tungsten deposit in the Nanling tungsten-tin mineralization belt was studied in terms of its geological framework, petrogenesis, tectonism, and metallogenesis. The results revealed that the Xintianling granite consists of different intrusive units, with the biotite granite being strongly associated with mineralization. The emplacement of the granite and associated mineralization occurred in the late Jurassic, and it is part of the large-scale mineralization in the Nanling region.
