摘 要: 从不同构造背景选取5个典型区域(TAG，Middle Valley，EPR 13oN，Lau Basin及Izu-Ogasawara Arc)，进行地质、地形特征、水体特征、周围沉积物矿物学和地球化学特征、地球物理特征及生物特征的综合研究对比工作，总结找矿标志，包括：水体中的找矿标志、周围沉积物中的找矿标志、地球物理的找矿标志和海底生物的找矿标志。在上述基础上，结合海上实际调查方法，建立可应用于海上调查的海底多金属硫化物调查方法。最后，将找矿标志与找矿方法相结合，并根据调查尺度的不同，建立不同尺度的找矿模型。

Abstract:Following the polymetallic nodules and cobalt-rich crust, seafloor polymetallic sulfide may be the third potential resources which can be used by mankind. However, the exploration on seafloor sulfide resource in China is still on its first step. Therefore, the summaries of the indicators and methods for seafloor sulfide resources and building practicable exploration mode will have significant meaning on the seafloor sulfide resource exploration and mining undergoing in China. Five areas from different tectonic settings were chosen as typical areas (TAG, Middle Valley, EPR 13 °N, Lau Basin, Izu-Ogasawara Arc), and their geological, topography characteristics, water mass characteristics, the mineralogical and geochemical characteristics of nearby sediments, life creature and geophysical characteristics were studied. The summarized exploration indicators include the indicators in the water mass and the nearby sediments, and indicators from geophysical and seafloor life creature. According to the above and together with the methods used on the sea investigation, the practicable methods for seafloor sulfide resource investigation were established. At last, according to different investigation scales, the different modes for seafloor sulfide resources exploration were established by integrated the indicators and methods.
Key words: polymetallic sulfide; exploration indicator; exploration methods; exploration mode
