马里亚纳海槽海底热液活动和热液硫化物研究

本文根据马里亚纳海槽海底热液活动和热液硫化物产状及矿物化学特征,探讨了存在的高温和中低温热液产物的矿物相及其赋存形式,认为是一种有别于大洋中脊和深断裂带的规模较小的海底热液活动类型.     

HYDROTHERMAL ACTIVITY AND SULFIDES IN THE MARIANA TROUGH

The submarine hydrothermal activity, its occurrence, the minerals and the chemical features of the hydrothermal sulfides in the Mariana Trough are described. The mineral phases and their existing forms of the hydrothermal products formed at high temperature and intermediate-low temperature are discussed. It has been considered that the hydrothermal activity in the Mariana Trough isa small-scale one, different from those on the mid-ocean ridges and in the deep fracture zones.     

马里亚纳海槽热液硅质烟囱上的自生绿脱石

本文详细地叙述了马里亚纳海槽热液硅质烟囱上自生绿脱石的矿物学和化学特征,并根据其产状对其形成进行了初步探讨,认为它是在构成烟囱外壁的非晶质氧化硅沉淀后,由于热液物化条件改变而在低温、氧化条件下从热液中直接沉淀形成的一种二八面体2:1型膨胀粘土矿物。
