| 2 | Genesis of Neogene Formation Waters in the Central Qaidam Basin:Clues from Hydrochemistry and Stable D-O-S-Sr Isotopes显示文摘Geological explorations have revealed plentiful Neogene formation waters in anticlines in the central Qaidam Basin(QB).However,the hydrochemistry and origin of these waters are obscure.In this study,the hydrochemistry and DO-S-Sr isotopes of these formation waters were determined to study their origin and evolution.The formation waters are enriched in Na-Ca-Cl,and depleted in Mg-K-SO4-HCO3ions with elevated Li-B-Br-Sr elements.The D-O isotopes prove that the formation waters originated from weak-evaporated meteoric waters,and experienced water-rock interactions.Ion comparisons and Caexcess-Nadeficitdiagrams suggest that solute sources of these waters include evaporite dissolution,waterrock interaction,and minor residual lake brines.Bacterial sulfate reduction and water-rock interactions are supported by the high S-Sr isotopes.The enriched Li-B-Br-Sr concentrations of these waters are in accord with the high geochemical background values of the QB.Regarding the genesis of the formation waters,it can be concluded that meteoric waters from the southern Kunlun Mountains were discharged into the basin,weakly evaporated,and then infiltrated into the Neogene strata through faults leaching the soluble ions and mixing with residual lake brines,and all experienced water-rock interactions and a sulphate reduction process. | HAN Guang PAN Tong LI Qingkuan FAN Qishun HU Yan LIU Jiubo ZHANG Xiying | 2023 | Acta Geologica Sinica(English Edition)2023，97，6： | 0 |
| 3 | Source Analysis of Lithium Deposit in Dong-Xi-Taijinaier Salt Lake of Qaidam Basin,Qinghai-Tibet Plateau显示文摘The Dong-Xi-Taijinaier Salt Lake(DXTSL) of Qaidam Basin is known as one of rich lithium reserves in China.However,the source of lithium deposits in this region remains unclear.The hydrochemistry and lithium isotopes(δ7Li) of water and solid samples along the Nalenggele River catchment were studied in combination with rock leaching experiments.The results showed the hot springs in the upstream contained high content of lithium and ratio of Li × 1 000/total dissolved solids(1.5–3.5),but the lower δ7Li values(4.33‰–11.59‰),meaning that it is one important lithium sources.The leaching experiments by the rich-lithium volcanic rocks(average content of 474.7 mg/kg) showed that under temperature of 20–80 ℃ and long time duration(24–96 h),the concentration of lithium released by leaching of the sampled volcanic rocks increased from 0.58 to 1.49 mg/L,with the leaching rate decreasing from 0.024 to 0.015 mg/(L·h) and the corresponding lithium release rate increasing from 29% to 74%.Calculation based on water-salt balance showed that the total amount of lithium contribution from hydrothermal fluids and volcanic rock weathering is about 4.99 and 0.29 Mt since 13.1 ka,respectively.Therefore,hot springs and leaching of volcanic rocks are main contributors to lithium deposit in DXTSL. | Jibin Han Hongchen Jiang Jiubo Liu Jianxin Xu Wenhua Han Haiyun Zhang | 2023 | Journal of Earth Science2023，34，4： | 0 |
