Other AbstractA total of 23 surface sediment samples were collected from the northern Bohai Sea,their detrital mineral assemblages and distribution characteristics as indicators of provenance and dispersal pattern in surface sediments were analyzed. Results showed that the average percentage composition of the detrital mineral is 17. 1%, including 9 species of light mineral ( 96. 77% on average) and 33 species of heavy mineral ( 3. 23% on average) . By using cluster method of Q type,it is showed that the northern Bohai Sea could be divided into two regional mineral assemblage zones along the east - west direction,due to the bedrock differences between two tectonic blocks,and further divided into 4 mineral assemblage zones by laws of watershed erosion source area differences and weathering handling. Provenance factor influence accounts for 41. 91% in total,while tide,ocean currents,and submarine topography factors account for 37. 46%. Assemblages and distributions pattern of detrital mineral in the northern Bohai Sea are mainly controlled by provenances,and also affected by hydrody namic and grain density.
