| 摘 要： | 通过对马里亚纳海槽两沉积岩芯中主要化学元素的因子分析,其结果表明,化学元素的共生组合和含量变化,与火山碎屑矿物以及大部分由海底玄武岩和玄武质火山玻璃蚀变而成的粘土矿物密切相关.岩芯的化学成分主要来自火山喷发物,因此,元素的地球化学特征反映了该区火山作用的影响.

| Abstract: | The results of factor analysis of major chemical elaments in the sedimentes of two cores from the Mariana Trough show that associations and content changes of chemical elements correlate well with volcaniclastc minerals and clay minerals which are largely formed by the alteration of submarine basalts and basaltic volcanic glass.The chemical components of the cores mainly orig- nate from volcanic ejecta.Thereby the geochemical characteristics of the major elements reflect the effect of volcanism in the trough area. |
