| 摘 要： | 马里亚纳海槽中央轴裂谷中的小扩张脊部位 ,广布火山喷发的玄武岩体 ,海底热液硫化物就是从这些岩体的裂隙中喷溢堆积起来的。利用我国“大洋一号”船拖网所获岩样进行了矿物学和岩石化学特征研究 ,认定为高铝低钾的大洋底玄武岩或拉斑玄武岩系列和钙 -碱玄武岩。为进一步弄清马里亚纳海槽区热液活动岩石学条件和探讨海槽区热液物质来源提供科学证据

| Abstract: | The basalt lithosomes are widely distributed on the small spreading ridge in the Mariana Trough central axis rift, and the submarine hydrothermal sulfides were erupted and accumulated from the cracks of these lithosomes. The rock samples collected by R/V "Dayang No.1" were used to make researches on the petrochemical and mineralogical features, and it is shown from the research results that these rocks are high-alumina and low-potassium oceanic tholeiite or tholeiite series and calc-alkaline basalt, which provides scientific basis for further clarifying the hydrothermal activity petrological conditions and the hydrothermal material sources in the Mariana Trough area. |
