| 摘 要： | 根据微量元素和稳定同位素的特征可以推断古盐度、古水温和古水深 ,恢复古沉积环境 ,并判断海平面的相对变化。对淄博地区上寒武统微量元素Sr、Ba、V、Ni和氧 碳同位素的研究结果表明其属于稳定的浅海环境 ,微量元素和氧 碳同位素的变化趋势与海平面的波动有一定的对应关系 ,而且从地球化学方面为层序地层的划分提供了依据。研究结果也表明 ,由于沉积地球化学特征的复杂性 ,不能简单地用一种因素来分析。

| Abstract: | Trace elements and carbon oxygen isotope can be used to do research on the sources of sediments,depositional environment,and fluctuations of sea level. It is analyzed that the characteristics of some trace elements including Sr, Ba, V, Ni and carbon oxygen isotope of the Upper Cambrian in Zibo area. The geochemical data on the palaeo temperatures, palaeo salinities, palaeo depth and depositional environment show that their rhythms are correspondent with the characteristics of the sequence stratigraphy in some degree, which demonstrates the feasibility of this method. On the other hand, the results also show the complexity of geochemistry. So a variety of facts should be considered synthetically. |
