Fig. 3: Grain size and geochemical records of core ZM01 from the ZFMB.

a Sand content, b Normalized Sr (normalized to total XRF counts), and c TOC/TN ratio. The gray line represents the average value of each parameter. The orange-filled columns represent periods of increased TC activity. The Sr content does not always match the sand content, which is most likely due to the narrower window of the Avaatech XRF (Fig. S1) compared to grain size samples.
