Summary: The study reviews the tectonic evolution of the Aravalli Craton from the Mesoarchean to the Neoproterozoic, suggesting that it was formed by the accretionary-collisional interactions between the Mewar gneissic terrane, the Aravalli fold belt, and the Delhi fold belt. The findings provide alternate explanations for existing tectonic models and highlight important unresolved issues.

Summary: This study investigates the nature of metasomatism at the crust-mantle interface by studying the Laixi basalt, which shows geochemical inheritance of island arc basalt-like trace-element patterns. The results suggest that the metasomatic agents are carbonated eclogite-derived melts, and imply the metasomatic reaction of mantle-wedge peridotite with carbonated silicate melt derived from the subducted upper crust in the continental subduction channel.

Summary: The controversial tectonic setting of the Paleo-Mesoproterozoic southern margin of the North China Craton has hindered a clear understanding of its role in the breakup of the Columbia/Nuna Supercontinent. Recent studies have revealed that sediments along the southern margin show varying sources and exhibit a progressive younging trend from north to south. The synthesized dataset supports the hypothesis that the southern NCC during the Paleo-Mesoproterozoic was in an active continental arc setting under a prolonged subduction regime.

Summary: This study investigates the lithospheric thinning in the eastern North China Craton (NCC) and Yangtze Craton (YZC) and proposes a five-stage model for the collision between these two cratons, highlighting the dominant geodynamic mechanisms in each stage. The results suggest that the lithospheric thinning is a consequence of the collision and subduction processes.

Summary: Based on geological data analysis, the ultra-deep Sinian Dengying Formation at the northwest margin of Yangtze craton region has significant exploration potential and huge lithologic gas reservoirs. This area was in the craton rifting stage from the Sinian to Early Cambrian, characterized by syn-sedimentary faults and rapid subsidence, as well as the formation of Dengying Formation platform margins. There are two sets of high-quality source rocks in the Sinian-Cambrian, and the mounds and shoals controlled by faults in the Dengying Formation platform margin have thick pore-type reservoirs. The mound-shoal body and source rocks form favorable source-reservoir combinations that can create large lithologic gas reservoirs.

Summary: The integration of seismic, gravity, and magnetic data reveals variations in crustal architecture along the Yucatan passive continental margin, particularly between the Yucatan salt basin and the Campeche salt basin. These variations explain the different tectonic histories of the basins, including pre-salt sedimentary basin, the pre-breakup locations of individual crustal blocks, and magmatic intrusions within the stretched continental crust.

Summary: The structural and metamorphic effects of a Devonian extension-shortening cycle in the NW Chinese Altai were investigated. The study revealed the presence of a sub-horizontal metamorphic fabric (S1) and identified the age and timing of the extension and shortening phases. The findings suggest that the cycles of extension and contraction in the Altai range could result from alternating retreating and advancing subduction.

Summary: This study provides systematic geochemical and geochronological research of well-preserved drill cores from the Piedmont of the Hala'alate Mountain in West Junggar. The results show that the Late Carboniferous rocks belong to the A-type granite series and arc-affinity geochemical compositions, indicating a partial melting of juvenile continental materials and a modified pyroxene-rich mantle source. The tectonic processes of West Junggar during the Carboniferous to Early Permian can be divided into three stages: sustained subduction processes, closure of the oceanic crust and collision orogenesis, and post-collision extension setting.

Summary: This study investigates the Carboniferous magmatism in East Junggar, China and provides geochronological, geochemical, and isotopic evidence for the subduction to postcollision tectonic transition. The early Carboniferous volcanic rocks originated from melting of a lithospheric mantle wedge fluxed by slab-derived fluids, while the late Carboniferous mafic dikes formed by partial melting of a spinel-bearing lithospheric mantle metasomatized by limited influx of subduction-related fluids. The late Carboniferous felsic volcanic rocks are geochemically equivalent to A2-type granites in the region and may have originated from melting of a juvenile basaltic lower crust. The study suggests a rapid tectonic transition from oceanic subduction to postcollisional extension in East Junggar during the Carboniferous.

Summary: The Indo-Myanmar Range is believed to be a remnant eastward-dipping subduction zone, with rodingites in the Indo-Myanmar Ophiolite Belt exhibiting complex variations in mineral assemblages and chemical compositions, classified into different categories based on their occurrence, minerals, and chemical composition. The formations of different rodingite types are likely related to seawater infiltration or serpentinization of oceanic lithosphere, with their mineralogy indicating formation temperatures of about 435 to 200 degrees Celsius, corresponding to greenschist facies.

Summary: This study presents data on the geochemical and isotope compositions of rocks and zircons from the late Neoproterozoic island arc structure of the Lake Zone. The results suggest that the plagiogranitoids originated from the depleted mantle sourced volcanic rocks, while the gabbro and quartz diorites originated from a less depleted mantle source, possibly mantle wedge peridotites. The two-feldspathic granites formed through the melting of the late Neoproterozoic-Cambrian island arc crust with the contribution of more differentiated crustal sources. This study confirms the intraoceanic setting of the late Neoproterozoic island arc in the Lake Zone.

Summary: This study provides insights into the Proterozoic assembly of Australia and its importance for reconstructing Proterozoic supercontinents. The presence of a substantial domain of juvenile Proterozoic lithosphere, the Percival Lakes province, between the West Australian and North Australian cratons is identified. The study suggests that the convergence of the cratons was younger than Columbia amalgamation and that Proterozoic Australia formed during the earliest phases of Rodinia assembly.

Summary: This study presents the first-ever report on the U-Pb isotopic ages of zircon and rutile in high-Cr chromitites of the Orhaneli Ophiolite Complex. The chromitites are formed from island arc melts and host various solid mineral inclusions. The zircons show characteristics of magmatic zircons and have Middle Devonian to Mesoproterozoic U-Pb isotopic ages, suggesting the possibility of an earlier Neoproterozoic metasomatic event affecting the chromitite bands.

Summary: This study documents the evolution of A-type granitoid magmatism during the Cryogenian tectonic transformation of the Yenisei Ridge. It explains the emplacement and cooling of the Strelka pluton, which represents the final stage of magmatism during the formation of the postcollisional Glushikha complex. These processes occurred simultaneously with the formation of mantle, mantle-crustal, and crustal rocks of the Tatarka complex, including the Yagodka pluton A-type granites during the early stage of active continental margin development.
