TL;DR: Loess has been widely distributed over Asia and North America and constitutes one of the most important surficial deposits that serve as terrestrial records of the Quaternary as mentioned in this paper, and the oldest Pleistocene loess in China is likely ∼2.6

TL;DR: In this article, the ages of displaced river terraces at two sites on the western and middle segments of the Fodongmo-Hongyazi fault were mapped with satellite imagery and field observations.

TL;DR: In this article, various indicators from published literatures for the provenance discrimination in the mud belt have been summarised in order to better understand the sediment source and dispersal pattern, the existing mineralogical and geochemical data of adjacent river systems, including the Changjiang River (CJR) and local rivers in Zhejiang, Fujian and Taiwan, need to be systematically reviewed.

TL;DR: In this paper, the coupling of a nanosecond laser ablation system with a large-scale multi-collector inductively coupled plasma mass spectrometer (Nu1700 MC-ICPMS, NP-1700) and a conventional Nu Plasma II MC-I-PMS (NP-II) for simultaneous S and Pb isotopic compositions of sulfide minerals was reported.

TL;DR: Li et al. as discussed by the authors proposed a classification scheme on the basis of the mud content in combination with the presumed transport mechanism, and applied it to the Triassic lacustrine Yanchang Formation in the southern Ordos Basin (China).

TL;DR: In this article, the authors classified the Neoproterozoic Malani Igneous Suite (MIS) in NW India, along with analogous magmatic rocks from the adjoining Nagarparkar region in SE Pakistan can be collectively classified as a Silicic-dominated Large Ignes Province (SLIP), which includes bimodal (predominantly felsic) volcanism, granite emplacement and mafic dyke intrusions.

TL;DR: In this paper, the authors systematically review the major features of Mesozoic granitic magmatism and associated Mo-Au-Pb-Zn mineralization in the southern margin of the North China Craton, including temporal and spatial variations of magmatic rocks, composition of ore-fluids, sources of ore metals, and metallogeny.

TL;DR: In this paper, the authors presented new zircon U-Pb ages, major-and trace-element data, and Hf isotopic compositions for bimodal volcanic rocks of the Zhaga Formation (ZF) in the western-middle segment of the Bangong-Nujiang suture zone (BNSZ), northern Tibet.

TL;DR: In this paper, the post-obductional extension on the northern flank of the mountain belt was investigated and two stages of deformation were deduced, the first stage is characterized by dextral motion, including local transtension.

TL;DR: In this paper, the authors report LA-ICP-MS U-Pb zircon ages, and whole-rock elemental and isotopic compositions of mafic rocks intruding into the North and South Liaohe Groups, with the aim of evaluating their petrogenetic affinities and metamorphic history, and their implications for the tectonic evolution of the JLJB.

TL;DR: In this paper, a method for predicting the collapse behavior due to wetting is proposed, which considers a strain path that includes a pre-collapse phase in which constant volume is maintained and a collapse phase that extends to the final matric suction to be experienced by collapsing soils during wetting.

TL;DR: In this paper, the authors presented geochemical data for the Upper Triassic black mudstones to determine their paleoenvironment conditions, provenance, and tectonic setting, and the results showed that the total REE concentrations of mudstones from these formations range from 169 to 214

TL;DR: In this article, the structural blocks of the Malan loess are found to be similar in shape, i.e., elongated with a length-to-width ratio of approximately 2.6.

TL;DR: In this paper, a high-resolution 2D seismic line transecting the two main Haima cold seep sites was acquired and processed, which provided new insights into the evolution of subsurface fluid flow in the study area.

TL;DR: In this article, the authors report multiple sedimentary proxy records for three piston gravity cores from the Haima seep of the South China Sea (SCS) from three sediment horizons, which are characterized by particular anomalies of low δ13CTIC values and high TS content, high TS and CRS contents, and high δ34Sacid-insoluble values, respectively.

TL;DR: In this paper, the authors reported a remarkable variation range in trace elements (Mo, V, U, Ni, Th, Co, Sc, Zn and Cu), molar Corg:P ratios and pyrite morphology from 27 core samples from one new drill hole (XY1, located in the Fenggang area, northern Guizhou) on the Yangtze Platform, South China.

TL;DR: In this article, the authors present replicated carbonate δ18O records of six stalagmites with subdecadal to multi-decadal resolutions from the Lianhua cave to reveal a detailed evolution of the East Asian Summer Monsoon intensity in northern China since 11.5 thousand years before present (ka BP, before 1950 CE).

TL;DR: In this paper, grain size measurements were performed for 298 samples of the 5.96m-long core PC338 spanning the past 36kyr recovered from the northern South China Sea (SCS).

TL;DR: Authigenic carbonates retrieved from sites ROV1 and ROV2 of the Haima hydrocarbon seeps of the South China Sea at approximately 1390m water depth were studied using lipid biomarker analyses as discussed by the authors.

TL;DR: In this article, the authors examined the latest outcrop, seismic, and drilling core data with the objective of investigating the regional stratigraphy to deeply recognize the evolution of rifting in the Tarim craton.
