- Abstract
The Gas Hure Salt Lake (GHSL) in the northwestern Qaidam Basin, western China, is rich in boron (B) resources, but its B‐resource origin is hardly known. Hydrochemical compositions and B isotope characteristics of different waters were collected around the GHSL, including the river water, stream water, spring water, salt‐lake brine, intercrystalline brine, well water, drilling brine, and solar pond brine. The hydrochemical signatures suggest that silicates, carbonates and evaporates are the main B‐bearing rocks during the water dynamic. The reservoir estimation of B resources shows that the Kulamulekesay River (KLMR) and the Atekan River (ATKR) contribute annually 18.3 tons and 22.84 tons of B, respectively, with a total amount of 11.72 × 104 tons of B during the past 5.7 ka. In comparison with the known B reservoir (32.96 × 104 tons) in the GHSL, a significant amount of B in the GHSL was probably recharged from deep fluids and sediments around the GHSL. The B concentration and B‐enrichment degree are shaped by the evaporation process, which are highly elevated at the carnallite and bischofite stages.
