Abstract: The major development in the study of spore-pollen GAI in last decade by petroleum spore-pollen workers in china is delt with in this paper.A spore-pol-len GAI clasfication standard and its correlation with those used by domestic and foreign collegues are defined.A table demonstrates the relation betweenspore-pollen GAI and generation stages of continental Tertiary hydrocarbon-bearing basins in china is presented.Some applications of spore-pollen GAI data are discussed.The au-thor further proves that spore-pollen GAI is a composites results of the effects of temperature,time and nature of the source rock.The significance of using spore-pollen GAI in searching for good source rock and promising source region is emphasized.
