“…Ten years later, DT continues to be a hypersaline lake with a salinity of 337-354 g/L. However, the salinity of XT shows a decrease, with a slight increase in Na + , K + , and SO 4 2− content and slight decreased in Mg 2+ and Cl − content [27,29]. Strangely, only 20-36 g/L of salinity in XT was detected in our study (Table 1).…”

“…Strangely, only 20-36 g/L of salinity in XT was detected in our study (Table 1). The big salinity gap between the salinity of the XT measured in this study and measured by Qin et al was most probably related to the sampling position [27]. This is because we collected the samples XT1~4 from the shore of XT, which was very near the road, while Qin's research was collected from the inter-brine area in the core mining area of XT Salt Lake.…”

“…Seasonal changes can affect the variation in these factors, which can lead to fluctuations in ion concentrations, such as those observed in the Taijinar Salt Lake, which experienced a reduction in size due to evaporation [25,26]. The Nalenggler River's influx of fresh water into XT has contributed to the observed decrease in salinity [27]. According to Fang's important findings, the Qinghai-Tibetan lakes are experiencing a water increase and salinity decrease due to climate warming [28].…”

The Dong Taijinar (DT) and Xi Taijinar (XT) Salt Lakes have been extensively researched for their mineral richness. However, the composition and distribution of their microbial communities are still poorly known. In this study, we employed metagenomic sequencing to explore the diversity and potential functions of the microbial populations in DT and XT. Our findings indicate that the salinity levels in DT (332.18–358.30 g/L) were tenfold higher than in XT (20.09–36.83 g/L). Notably, archaea dominated the DT domain at 96.16%, while bacteria prevailed in XT at 93.09%. In DT, the bacterial community comprised 33 phyla and 1717 genera, with Marinobacter emerging as the dominant genus, showing a positive correlation with the total phosphorus content. The archaeal community in DT included four main phyla and 153 genera. The most abundant genera were Natronomonas (24.61%) and Halorubrum (23.69%), which had a strong positive correlation with the concentrations of Na+, Ca2+, and Cl−. Conversely, XT hosted 33 phyla and 1906 bacterial genera, with Loktanella as the dominant genus. The archaeal taxonomy in XT encompassed four phyla and 149 genera. In both salt lakes, Proteobacteria and Euryarchaeota were the most abundant bacterial and archaeal phyla, respectively. Our analysis of the halophilic mechanisms of these microorganisms suggests that the bacteria in XT tend to synthesize compatible solutes, whereas the archaea in DT adopt a ‘salt-in’ strategy, integrating salt into their cellular machinery to cope with the high-salinity environment.

The hydrogeochemical research of groundwater in the Bieletan area, China’s largest potash producing zone, used a variety of methods, including multivariate analysis, saturation index, and hydrogeochemical modeling. Water samples were collected and analyzed for physicochemical parameters, along with soluble ions from soil cores. The results showed that total dissolved solids (TDS) of groundwater exceeded 300 g/L, with the main hydrochemical characteristics being Cl-Mg type and Cl-Na type. Groundwater is recharged by lake water and canal water, with evaporation being the main factor affecting water chemistry. Hydrogeochemical modeling analyzed the processes occurring from these two different recharge sources: mineral precipitation mainly occurred with lake water recharge, while mineral dissolution mainly occurred with canal water recharge. Regarding potash dissolution, canal water and lake water recharge resulted in 8.860 mmol/L of polyhalite dissolution and 0.278 mmol/L of carnallite dissolution, respectively. This study highlights the complex hydrogeochemical processes controlling groundwater in the potash-rich Bieletan area, providing insights for water resource management and potash mining.
