The study of the relationship between lake carbonate and climate will help to understand the mechanism of carbon cycle in the lake system. Juyeze is a terminal lake in a typical inland basin in China's arid region. This data measured the particle size, carbonate content and mineralogical composition of sediment samples at different locations of Juyeze.
