“…The Qaidam Basin (Fig. 1a, b), the largest closed basin of the Tibetan Plateau, has the most plentiful number of salt lakes and salt playas and almost all varieties of salt deposits (Zheng et al, 1993), as well as rich oil and gas reservoirs (Tan et al, 2011;Ye et al, 2014). Considerable research has been conducted to provide support for water supply and mineral resource exploitation in the basin (Chen and Bowler, 1986;Vengosh et al, 1995;Lowenstein and Risacher, 2009;Li et al, 2010;Tan et al, 2011;Hou et al, 2014;Ye et al, 2014;Chen et al, 2017).…”

Groundwater origin, flow and geochemical evolution in the Golmud River watershed of the Qaidam Basin was assessed using hydrogeochemical, isotopic and numerical approaches. The stable isotopic results show groundwater in the basin originates from precipitation and meltwater in the mountainous areas of the Tibetan Plateau. Modern water was found in the alluvial fan and shallow aquifers of the loess plain. Deep confined groundwater was recharged by paleowater during the late Pleistocene and Holocene under a cold climate. Groundwater in the low-lying depression of the central basin is composed of paleobrines migrated from the western part of the basin due to tectonic uplift in the geological past. Groundwater chemistry is controlled by mineral dissolution (halite, gypsum, anhydrite, mirabilite), silicate weathering, cation exchange, evaporation and mineral precipitation (halite, gypsum, anhydrite, aragonite, calcite, dolomite) and varies from fresh to brine with the water types evolving from HCO 3 · Cl-Ca · Mg · Na to Cl-Na, Cl-K-Na and Cl-Mg type along the flow path. Groundwater flow patterns are closely related to stratigraphic control and lithological distribution. Three hierarchical groundwater flow systems, namely local, intermediate and regional, were identified using numerical modeling. The quantity of water discharge from these three systems accounts for approximately 83 %, 14 % and 3 %, respectively, of the total groundwater quantity of the watershed. This study can enhance the understanding of groundwater origin, circulation and evolution in the Qaidam Basin as well as other arid endorheic watersheds in northwestern China and elsewhere worldwide.

“…The sediments in the caps consist mainly of gypsum, while the halite crust covers the ground surface around the study area. Previous drilling to a depth of ∼100 m in the vicinity of the study area has shown that halite is the main mineral in the upper ∼70 m and that the deeper part is dominated by mudstone (Ye et al., 2014). It is unlikely that aeolian gypsum from a distant area was deposited exclusively in the cap structures without affecting the surrounding ground surface.…”

“…The Ca, Fe, and S in the sediments may have been leached by groundwater at some point and eventually transported to the surface to be deposited. Previous drilling near the study area has shown that there are several thin layers of epsomite and gypsum in the subsurface (Ye et al, 2014), which could be a possible Ca and S source. However, these layers show no evidence of high Fe concentrations.…”

The coexistence of sulfates and iron oxides is widespread on Mars, including at Meridiani Planum, the Opportunity rover's landing site. However, the formation mechanism is still poorly understood. Here, we report evaporitic iron oxyhydroxides and gypsum deposited as round caps in the center of brine pools in a playa area of the western Qaidam Basin in the northern Tibetan Plateau. Geochemical and mineralogical analyses indicate that the gypsum is precipitated in situ by strong evaporation of subsurface percolating brine containing dissolved iron. We suggest that the transport of iron from the anoxic subsurface and the evaporation of upwelling groundwater in an oxidized and hyperarid environment may have led to the co‐deposition of sulfates and iron oxides at Meridiani Planum and other similar sites on Mars. Our results also suggest that the subsurface water cycle could be an important source of iron mobility even under an oxidizing atmosphere and cold climatic conditions on Mars. Groundwater evaporation during the desiccation of Mars after the late Noachian may have contributed to the heterogeneous distribution of iron and the widespread coexistence of sulfates and iron oxides on the martian surface.

“…In the mountain area the dominant types of rocks are generally granodiorite, plagioclase granite and quartz diorite (Rong et al, 2003;Ye et al, 2014a); at the alluvial fan (overflowing area) the main rocks consist of pluvial sands, gravels and sandy clay; whereas at the salt lake plain, the lithology is mainly composed of clay, salts, and gypsum-dominated evaporites (Zhang, 1987;Rong et al, 2003;Ye et al, 2014b).…”

Boron (B) is an indispensable element in modern life, with uses in, for example, the chemical industry, medicine, the aviation industry, and the construction business. More than 30% B is stored in salt-lake brine and sediments in the Qaidam Basin (QB), western China (Sun et al., 2014).Thus, it is of great significance to identify the B sources and to explore the B resources in the salt lakes in the Qaidam Basin.Up to date, only a few works have been aimed at identifying the origins of B in some of the salt lakes in the QB, such as Qarhan salt lake (
