Fig. 2: Stratigraphic columns with isotopic and elemental profiles of CJYZ and JLW sections.

Stratigraphic column with δ13Ccarb30,33, δ18Ocarb30,33, δ7Licarb, and elemental profiles of the (a) CJYZ and b JLW sections. The Shuram Excursion event is marked by the light blue region. The filled and open diamonds in the CJYZ section represent bulk carbonate data that leached by 0.3 M and 0.5 M acetic acid, respectively. The JLW section has a short gap in the pre-SE due to poor outcrop during our collection of samples.
