Summary: The Dong-Xi-Taijinaier Salt Lake (DXTSL) in the Qaidam Basin is a significant lithium reserve in China, but the origin of the lithium deposits in this region is still unknown. The study investigated the hydrochemistry and lithium isotopes of water and solid samples from the Nalenggele River catchment, along with rock leaching experiments. The results showed that hot springs in the upstream had high lithium content but low 87Li values, indicating them as an important lithium source. Additionally, leaching experiments revealed that volcanic rock weathering and hot springs are the main contributors to the lithium deposits in DXTSL.

Summary: This paper presents the results of systematic geochemical and isotopic analyses of brines in the Tertiary and Quaternary sediments of the Qaidam Basin on the Qinghai-Tibet Plateau. The study reveals the enrichment of lithium (Li) and rubidium (Rb) in paleobrines, with the input of volcanic geothermal water being a key mechanism. The research also highlights the influence of river water replenishment and water-rock reactions on critical metal mineralization.

Summary: This paper investigates the ore-forming mechanism of lithium-rich brine in the Yiliping Salt Lake in the central part of the Qaidam Basin, China, with a focus on the control of paleoclimate on the evolution of salt lake brine. By conducting halite uranium series dating and halite fluid inclusion homogeneity temperature test, the temperature of the salt lake brine during halite precipitation is determined, and the relationship between the formation of lithium-rich brine and ancient climate change is studied.

Summary: Through cycling experiments of lithium battery materials in different brine environments, this study found that diluting high-viscosity brine with water can significantly enhance the capacity and rate capability of the battery. In addition, electrochemical and X-ray diffraction analysis showed that high lithium selectivity was maintained during cycling, while Raman spectra and scanning electron microscopy images revealed that capacity degradation may be caused by particle cracking due to interfacial reactions.

Summary: In this study, the evolution of intercrystalline brine in the Kunteyi Basin was analyzed using major ion concentrations and isotopic ratios. The results showed that the brine had a high concentration of total dissolved solids and most of the ions were enriched. The isotopic values indicated that atmospheric precipitation was the primary source of water in the brine, while halite dissolution influenced its salinity.

Summary: The study reveals variations in the underground brine table and potassium-bearing grade before and after large-scale mining in the Lop Nor potash deposit. Results show a decrease in both the underground brine table and potassium sulfate grade to varying degrees in different sub-mineral areas. The research provides a theoretical basis for the rational development and sustainable use of potassium-rich brines in the Lop Nor basin.

Summary: This study investigates the sources and dynamic behavior of lithium in the salt lakes fed by the Nalenggele River in the Qaidam Basin, China. The results indicate that the dissolved lithium in the basin mainly comes from hot springs, and the lithium in the streams shows various isotopic fractionation behavior. These findings enhance the understanding of lithium sources and enrichment in brines, as well as the metallogenic process in hyper-arid regions.

Summary: This study utilized Optically Stimulated Luminescence (OSL) dating to investigate typical brine lithium deposits on the Qinghai-Tibetan Plateau, providing insights into the age and climatic environment characteristics of lithium deposits in the Qaidam Basin. The results show that brine lithium deposits in the Qaidam Basin began forming 40 ka ago, with South American deposits being older and Tibetan deposits being the youngest. The climate around East Taijnar Salt Lake, West Taijnar Salt Lake, and Yiliping Salt Lake exhibited different characteristics at different time periods.

Summary: The study analyzed zircon megacrysts from Quaternary intraplate basaltic volcanoes in northeastern Cambodia, revealing complex Li isotopic variations and suggesting multi-mode Li diffusion influenced by variable trace element inventories within individual crystals. The research also indicated diffusion-driven equilibration between zircon and basaltic melt, with pre-eruptive heating timescales estimated to be about 18 days.

Summary: The study reveals important sedimentary lithofacies and mineralogical characteristics of a uranium mineralization interval in the western Qaidam Basin, with coffinite and uraninite as the main uranium minerals, and suggests that organic carbon may have been derived from hydrocarbons sourced from the deeper part of the basin or biogenic gases at shallow depths. The unconformity at the Neogene-Quaternary transition may be a favorable interval for uranium mineralization where oxidizing fluids carrying uranium met with reducing fluids carrying hydrocarbons in this basin.

Summary: The study found that salt samples from salt lakes are rich in various fatty acid compounds, as well as glycerol dialkyl glycerol tetraethers (GDGTs) and archaeol compounds. Compared to samples with high salinity, clay samples not only have higher content of fatty acids, GDGTs and archaeol compounds, but also a more diverse lipid composition.

Summary: Brine lakes serve as natural laboratories for studying groundwater influences and mineralization processes in arid environments. Da Qaidam Lake in China is one of the largest brine lakes for boron and lithium resources, with deep hydrothermal and shallow groundwater as the dominant sources. This study used radium isotopes and multi-tracer models to partition deep and shallow LGD and quantify lithium and boron loadings, contributing to the understanding of lithium and boron budgets in brine lakes worldwide.
