本文根据钻孔岩芯化学分析资料,研究了华北平原北部全新世沉积地层中化学元素Fe、Mn、Ca、Mg、Cu、Ni、Zn、B等以及CaCO_3的分布,它们的迁移和积累受制于气候条件,沉积环境以及海洋等多种因素的控制。在全新世早、中、晚三个沉积阶段中,元素Ca、Mg以及CaCO_3的含量具有高—低—高的分布特征,而元素Fe、Mu、Cu、Ni、Zn和B则表现出低—高—低的变化趋势。 According to the chemical analysis data of borehole core, the distributions of chemical elements such as Fe, Mn, Ca, Mg, Cu, Ni, Zn, B and CaCO3 in the Holocene sedimentary stratum in northern North China Plain are studied. Their migration and accumulation are controlled by Climate conditions, sedimentary environment and the ocean and many other factors. In the early, middle and late Holocene sedimentary stages, the contents of Ca, Mg and CaCO3 are high-low-high and the contents of Fe, Mu, Cu, Ni, Zn and B are low- High-low trend.
