Figure 1: Isotopic results of sedimentary carbonates of the Araras platform.

Sulfur isotope composition of sulfate (δ³⁴S_CAS and Δ³³S_CAS) and pyrite (δ³⁴S_pyr) of the Araras carbonates. Results are given in ‰ versus CTD. Terconi, Carmelo and Camil section are represented as a single composite stratigraphic log¹⁷.
