英文摘要	Given their critical impact on radiative forcing, sulfate aerosols have been extensively studied using their isotope signatures (δ ³⁴ S, ∆ ³³ S, ∆ ³⁶ S, δ ¹⁸ O, and ∆ ¹⁷ O). A striking observation is that ∆ ³³ S > 0 ‰, implying a missing reservoir in the sulfur cycle. Here, we measured ∆ ³³ S < 0 ‰ in black crust sulfates (i.e., formed on carbonate walls) that must therefore result from distinct chemical pathway(s) compared to sulfate aerosols, and they may well represent this complementary reservoir.
