Figure F1. Ion chromatograms (m/z 85) illustrating the abundance of n-alkanes for selected samples, Sites C0013, C0014, and C0017. Lithostratigraphic positions of samples and their locations within the Iheya hydrothermal system drilled during Expedition 331 are shown. C14 = C14 n-alkane, Ph = phytane, VRE = vitrinite reflectance equivalent.
