摘要

摘要: 对苏北盆地XH1#钻孔沉积物磁化率与粒度组分的相关性进行了研究，研究结果表明，此钻孔沉积物磁化率与粒度组分的相关性在不同深度段内有着不同的表现：在350～247 m深度段内，磁化率大小与中值粒径大小表现为负相关、与4～12Φ各粒级组分百分含量表现为正相关；在234～0 m深度段内，磁化率大小与中值粒径大小表现为正相关，与1～3Φ粒级组分百分含量表现为密切的正相关；247～234 m深度段是上述两种相关性变化的一个过渡阶段。环境磁学实验结果也揭示出在上下两个深度段内磁性矿物组成上也存在差异。这种不同深度段内磁化率与粒度组分相关性上的大的变化，以及磁性矿物组成上的差异共同揭示出，在深度247～234 m这段沉积物的沉积过程中，苏北盆地内可能发生了一次重大的事件，正是这次重大事件的发生导致了碎屑沉积物来源的改变，出现了上下两部分磁化率大小与粒度组分相关性上的差异。

Abstract: Based on the synthetic study on the correlations between magnetic susceptibility and the content of the different grain size〖KG*2〗of XH1# core in northern Jiangsu basin, this paper shows that the correlation is different〖KG*2〗in various depth: 350~247m, the mass susceptibility correlates negatively with〖KG*2〗mid-grain sizes, but correlates positively with the content〖KG*2〗of 4~12Φ; 234~0m, the mass susceptibility correlates positively with〖KG*2〗mid-grain sizes, and correlates positively with the content〖KG*2〗of 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.〖KG*2〗The results of environmental magnetism research〖KG*2〗show that the components〖KG*2〗of magnetic mineral are also different〖KG*2〗in the upper stratum(234~0m) and the lower stratum(350~247m). The difference〖KG*2〗of the correlations between magnetic susceptibility and the content of the different grain size,〖KG*2〗and the components〖KG*2〗of magnetic mineral in various depth reveal that, in the course〖KG*2〗of 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 sediment〖KG*2〗origin.
