Coccolith standard distribution in shore and shallow sea area is discussed i n this paper. Such standard distribution is proposed based on the ecological cha racter of the coccolithopora. Coccoliths in 62 samples collected in submarine ri dges of Yellow Sea is used to be an example to build the index distribution pa ttern. According to the pattern, the sedimentation type of each sampling site ca n be easily ascertained
