(a) The pristane/phytane (Pr/Ph) ratios of the source rocks in the Huizhou Sag () |
(b) Representative partial mass chromatograms ( = 217,231) of the saturate fractions for the Eocene source rocks in the Huizhou Sag (4-MS represents 4-methyl sterane; C27, C28, and C29 represent C27 sterane 20R, C28 sterane 20R, and C29 sterane 20R, resp.). |
