现代海底热液成矿作用综述

现代海底热液成矿作用是一种重要的成矿作用。海底热液系统主要分布在大洋中脊、弧后盆地、板内火山活动中心等张裂性环境中 ,不同的环境具有类似的成矿模式。海底大洋中脊热液作用的主要产物为黑烟囱、白烟囱。现代海底硫化物堆积过程是烟囱生长、倒塌和热液流体在其开放空间充填与交代的过程 ,硫化物的形成首先是通过硫化物烟囱来完成。提出了运用成矿系统理论来研究海底热液作用的方法

A SUMMARY OF MODERN SEAFLOOR HYDROTHERMAL MINERALIZATION

Modern seafloor hydrothermal process is an important ore-forming process. Seafloor hydrothermal system mainly distributes in the tensile environment such as MOR,Arc-rear basin,intraplate volcanic center and so on. However, different environment possess similar ore-forming modle.The main product of hydrothermal activity of Mid-Ocean Ridge are black chimney and white chimney.The accumulation of modern benthic sulphide is the process of chimney growth,collapse and hydrothermal fluid infilling and metasomatism in the open space and the formation of sulphide is completed by sulfide chmney.The paper put forward a way to study seafloor hydrothermalism by using ore-forming system theory.
