Boron source and evolution of the Zabuye salt lake, Tibet: Indication from boron geochemistry and isotope

Wenjie Zhang et al.

Summary: This study systematically measured the geochemical compositions and B isotopes of liquid and solid reservoirs in the Zabuye drainage basin to reveal the B isotopic fractionation and provide constraints on potential B sources. The results showed that the enriched B in the Zabuye salt lake was mainly derived from hydrothermal activities, and the depleted B isotopic compositions of the brine were caused by the redissolution of B-bearing minerals. These findings enhance the understanding of B isotopic fractionation and ore-forming mechanisms on the Tibetan Plateau.

Lithium and Sr isotopic composition of salar deposits in the Central Andes across space and time: the Salar de Pozuelos, Argentina

Anette Meixner et al.

Summary: The Central Andes of South America have the largest known lithium resources, with speculation still surrounding the primary sources and mobilisation processes. Chemical weathering and hydrothermal systems are considered the main mechanisms of Li extraction. Data from the Salar de Pozuelos indicate that near-surface chemical weathering is the dominant mobilisation process of Li, with evaporation causing enrichment.

Hydrogeochemical processes controlling the water composition in a hyperarid environment: New insights from Li, B, and Sr isotopes in the Salar de Atacama

Fernanda Alvarez-Amado et al.

Summary: Northern Chile, NW Argentina, and SW Bolivia, known as the lithium triangle, are world-class reservoirs of lithium. This study focuses on the Salar de Atacama (SDA) in northern Chile, which is one of the richest lithium reservoirs in the region. Isotopic methods and chemical composition analysis were used to understand the hydrogeochemical processes controlling the water composition and solute distribution in SDA. The results confirmed that weathering of ignimbrites is one of the most important processes influencing the origin of solutes, such as lithium, in the region.
