    Abstract
  • Organic maceral and sub-maceral characteristics of source rocks in Paleogene in the Pearl River Mouth Basin have been studied by means of compositive optics of organic petrology.It is also discussed the hydrocarbon generating potentials and features by element analyses on kerogen,rock-eval analyses and high temperature and pressure simulation on source rocks.Relatively abundant exinite and exinite-vitrinite A rich in hydrogen result in oil-prone type Ⅰ-Ⅱ1 of organic matter in medium-deep lacustrine facies.Relatively abundant exinite-vitrinite B pool in hydrogen and vitrinite result in gas and condensate-prone type Ⅲ-Ⅱ2 of organic matter in shore-shallow lacustrine and swamp facies.Sapropelinite and intertinite contents are low.The two types of source rocks have different hydrocarbon-generating features in various phases. Those conclusions are important for the further studies of organic facies and exploration potential and prospect in different depressions(sags) in the basin.
