山东灵山岛青山群硅质岩的地球化学特征及地质意义
|
摘要
山东东部灵山岛地区发育一套火山碎屑岩、硅质岩、火山碎屑岩夹火山弹的特殊沉积层,为查明这套地层中硅质岩的形成原因及其大地构造背景,对硅质岩进行岩相学和地球化学分析。结果表明,研究区SiO_2平均含量为70. 08%,Fe/Ti、(Fe+Mn)/Ti、δEu、Ba/Sr、Ni/Co及地球化学示踪投影指示其为热水成因; Al/(Al+Fe+Mn)、Al_2O_3/(Al_2O_3+Fe2O3)、MnO/TiO_2、V/Cr、Ni/Co、Th/Sc、U/Th、δCe、(La/Ce)N表明其形成于大陆边缘环境; K2O/Na2O、Al_2O_3/TiO_2、SiO_2/Al_2O_3、SiO_2/MgO、Ni/Co值暗示其形成与火山作用有关。研究区硅质岩应为热水成因,且形成过程中受到陆源物质和火山作用的双重影响,形成于大陆边缘裂谷沉积环境。
A set of sedimentary rocks consisting of volcaniclastic rock,siliceous rocks,and volcaniclastic rock with volcanic bomb are developed in the offshore of the Lingshan island,Shandong Province. In order to understand the genesis and tectonic settings of these sedimentary rocks,petrography,major and trace element analysis of siliceous rocks are conducted. The rocks have low SiO_2 from 67. 30% to 73. 31% with an average of 70. 08%. Their Fe/Ti,( Fe+Mn)/Ti,Ba/Sr,Ni/Co ratios,δEu values indicate a hydrothermal origin. Al/( Al+Fe+Mn),Al_2O_3/( Al_2O_3+Fe2 O3),MnO/TiO_2,V/Cr,Ni/Co,Th/Sc,U/Th,( La/Ce)Nratios and δCe values suggest that siliceous rocks are formed in continental margin environment. K2 O/Na2 O,Al_2O_3/TiO_2,SiO_2/Al_2O_3,SiO_2/MgO and Ni/Co ratios reflect that the rocks are particularly related to volcanism. In conclusion,the siliceous rocks were hydrothermal origin and affected by terrigenous matter and volcanism in the continental margin rift.
