| 摘 要： | 笔者采用ICP-MS测试分析技术,对川东南-黔中及其周边地区震旦-志留纪地层28件样品进行了B、V、Ni、Sr、Ba、Th、U等指示沉积环境的敏感微量元素做了系统测试分析,采用GB/T14506.28-93硅酸盐岩石化学分析方法和X射线荧光光谱法测定主要元素和微量元素含量,并探讨了Sr/Ba、V/Ni、V/(V+Ni)、Sr/Ca、Ca/Mg、Th/U比值与沉积环境的对应关系.分析结果表明,本区下组合沉积环境主要为半深海、深海及浅海滞流环境.元素空间分布的差异性反映了沉积环境的区域性变化. |
| 关 键 词： | 川东南-黔中及其周边地区 微量元素 震旦-志留系 沉积环境 |

| Abstract: | This paper deals with the contents of such elements as B,V,Ni,Sr,Ba,Th and U by using the ICPMS(Inductively Coupled Plasma-Ms Spectrometer) technique for 28 samples collected from Sinian-Silurian strata in Chuandongnan-Qianzhong region and its periphery areas. The contents of major and trace elements were determined by means of GB/T14506.28-93 and X-Ray Fluorescence Spectrometry. The corresponding relationships between the Sr/Ba,V/Ni,V/(V +Ni) ,Sr/Ca,Ca/Mg and Th/U values and the sedimentary environments we... |
