Summary: Episodic Neoproterozoic magmatic suites in the Altyn Tagh, NW China, are believed to be associated with the breakup of the Rodinia supercontinent. The characteristics of A-type granites derived from a juvenile source, highly fractionated gneissic granites, and a diabase derived from an enriched asthenosphere mantle were observed in this region. The similarity in age of magmatism and metamorphism in the Altyn Tagh-North Qaidam-East Kunlun regions suggests that they collectively represent the basement of the Qaidam block.

Summary: The Naxiguole Banded Iron Formation (BIF) in the Eastern Kunlun Orogenic Belt, Northwest China, has been studied for its age and origin. It was formed in a sedimentary basin within an active continental island arc, with contributions from terrestrial clastic material and seawater. The findings suggest its similarities with Superior-type BIFs worldwide.

Summary: Neoproterozoic granitoids in the Altyn Tagh region provide important insights into the early geological evolution and tectonic connections with the East Kunlun and North Qaidam areas. The age and petrological characteristics of these granitoids suggest a late syn- to post-collisional setting and a possible connection with Laurentia, Baltica, and Amazonia during the Neoproterozoic.

Summary: The Paleogene sedimentary successions of the Tarim Basin in western China are reconstructed to understand the palaeogeographic evolution and palaeoenvironmental changes. The study reveals the major regression of the proto-Paratethys Sea, the transition from marine to continental-lacustrine sedimentation, and the role of tectonic and eustatic forces in controlling the late Paleogene transgression regression. The findings provide insights into the sedimentary response to Paleogene sea-level change and tectonic events in Central Asia.

Summary: New geochronological and geochemical analyses of Neoproterozoic magmatic rocks in the Aksu area of NW China reveal evidence of an oceanic subduction setting with arc-back-arc system, similar to the IzuBonin subduction system. These findings suggest continuous oceanic subduction beneath the northern margin of the Tarim Block occurred during ca. 910-870 Ma, supporting the accretionary process of the Tarim Block to Rodinia during the early Neoproterozoic.

Summary: This study thoroughly investigates the evolution of groundwater circulation in the Aksu River Basin, providing insights into the formation mechanism and evolutionary pattern of the groundwater flow systems. The study reveals the complex coupling relationship between the palaeosedimentary environment, palaeoclimate, and basin GFS, influenced by neotectonic movement and climate fluctuation.

Summary: The Tarim Block consists of the Northern Tarim terrane (NTT) and the Southern Tarim terrane (STT), which exhibit distinct geological features indicating independent pre-Cryogenian evolutions. New geochronological data from the Tarim Block reveal different deposition times for various glacial deposits, consistent with global glaciations. The data also support the idea that the STT may have originated from the Congo Craton while the NTT drifted from North China-India, and later amalgamated due to circum-Rodinia subduction.

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: Carbon isotope stratigraphic records across the Triassic-Jurassic boundary show frequent perturbations of global carbon cycles, linked to the pulsed emplacement of the Central Atlantic Magmatic Province. Detailed carbon isotope stratigraphic reports from high-latitude terrestrial deposition are limited, hindering the understanding of climatic response. Research in NW China's Junggar Basin reveals significant carbon isotope excursions, allowing global stratigraphic correlation and identification of the end-Triassic mass extinction. Climatic patterns rapidly changed across the boundary, coinciding with a bloom of fern spores, increased wildfire activities, enhanced hydrological cycles, and soil loss.

Summary: Recent research on the Tarim Craton's northern margin has revealed a composite dike that sheds new light on the Neoproterozoic tectonic transition in the region. The dike consists of deformed granites and undeformed diabases, providing insight into two-episode igneous events following orogenic metamorphism. The granites have S-type affinities and are derived from accretionary complex metasedimentary rocks, while the diabases likely originate from partial melting of metasomatized subcontinental lithospheric mantle. This composite dike highlights a rapid tectonic shift from orogeny to intraplate extension during the mid-Neoproterozoic.

Summary: The study established inversion maps for metallic elements based on geochemical exploration data and remote sensing data, providing a reference for metallic ore prospecting. The research found that ASTER spectrum has higher accuracy than WorldView-2 in some element inversions, while the high spatial resolution of WorldView-2 enhances the precision of the inversion maps.

Summary: The study suggests that during the Neoproterozoic period, there was a change in the subduction style of the Tarim Craton, transitioning from advancing to retreating subduction, which may be related to the breakup of Rodinia.
