Based on the synthetic study on the correlations between magnetic susceptibility and the content of the different grain sizeof XH-1# core in northern Jiangsu basin, this paper shows that the correlation is differentin various depth: 350~247m, the mass susceptibility correlates negatively withmid-grain sizes, but correlates positively with the contentof 4~12Φ; 234~0m, the mass susceptibility correlates positively withmid-grain sizes, and correlates positively with the contentof 1~3Φ; The depth of 247~234m is the transition period of the transform of the correlations between magnetic susceptibility and the content of the different grain size.The results of environmental magnetism researchshow that the componentsof magnetic mineral are also differentin the upper stratum(234~0m) and the lower stratum(350~247m). The differenceof the correlations between magnetic susceptibility and the content of the different grain size,and the componentsof magnetic mineral in various depth reveal that, in the courseof the sediment deposition in the depth 247~234m, one great event may have happened in Northern Jiangsu Basin, this event led to the change of detrital sedimentorigin.
