迄今为止,已发现有自然金产出的现代海底热液系统及其相关的块状硫化物矿床,主要分布于大西洋的慢速扩张洋脊和西太平洋的弧后盆地内(Herzig等,1993;Hannington等,1995;Binns等,1997;Murphy和Meyer,1998;Moss和Scott,2001)。相比之下,前人对印度洋中脊海底热液活动区金矿化的研 To date, modern seafloor hydrothermal systems with natural gold production and their associated massive sulphide deposits have been found, mainly in the slow oceanic ridges of the Atlantic Ocean and back-arc basins in the western Pacific (Herzig et al., 1993; Hannington et al., 1995; Binns et al., 1997; Murphy and Meyer, 1998; Moss and Scott, 2001). In contrast, previous studies of the gold mineralization of the seabed hydrothermal activity zone in the Indian Ocean ridges
