| 摘 要： | 热液羽状流是海底热液活动的重要标志，海底多金属硫化物是热液活动的产物。现阶段洋中脊多金属硫化物勘探工作的第一步是开展热液羽状流的近底探测；综合各类异常信息，实现从发现热液活动喷口到发现矿床的突破。本文以热液羽状流为研究对象，从羽状流的近底探测、扩散机制和分布特征3个方面，概述了最新的研究进展和有待完善的方面，阐述了羽状流在洋中脊多金属硫化物找矿中的指示作用，最后总结性地指出时空连续性、参数多元化将是热液探测的发展趋势，有助于提升对热液羽状流分布特征的认识，将为热液区分布模式的研究提供更加精细的探测资料。

| Abstract: | Hydrothermal plume is an important symbol of hydrothermal activity. Seafloor polymetallic sulfide deposits are products of hydrothermal activity. At the present stage, seafloor polymetallic sulfide prospection and exploration in the mid-ocean ridges are mainly based on the detection of hydrothermal plume and combined with the comprehensive anomaly detection information to realize the breakthrough from the discovery of hydrothermal vents to the discovery of mineral deposits. Based on the hydrothermal plume as the research object, from the three aspects of near-bottom observations, dispersion mechanism and distribution characteristics, this paper summarizes the latest progress and aspects need to be improved of hydrothermal plume, and emphasizes the hydrothermal mapping as a prospective tool for seafloor polymetallic sulfide deposits in the mid-ocean ridges. Finally, this paper points out in conclusion that the spatial and temporal continuity, parameter diversification will be the development trend of hydrothermal detection, which will help promote understanding of hydrothermal plume distribution characteristics and will provide more detailed data to the study on the model of the hydrothermal fields. |
