Abstract
Based on biomarker proxies, the depositional environment of the Gudao Oils can be divided into two phases. In the first (GD2-19-55 and GD8-27N12), deposition occurred completely in seawater-dominated oxic to suboxic conditions, with primary input of terrestrial higher plants with an abundant influx of aquatic organisms. The second phase (GD2-7-41, GD-KD-162, GD-KD-18-168 and GD-KD-45) consisted of mainly seawater anoxic to suboxic/oxic conditions along with a small freshwater influence, with diluted organic matte derived from phytoplankton and a lesser influence from terrestrial higher plants. In addition, the vitrinite reflectance (Ro) of ca. 0.73-0.89% and methylphenanthrene index (MPI-1) of ca. 0.55-0.82 indicate the organic matter to be mature.
