CURRENT STATUS AND PERSPECTIVE ON RESEARCH OF SEAFLOOR HYDROTHERMAL SULFIDE DEPOSITS

Modern seafloor hydrothermal activities are widely distributed in world oceans. This paper is to make an introduction to the mining status of seafloor hydrothermal sulfide and a summarization of the application procedure for mining privilege and the status of sulfide resource evaluation. Understanding the spatial and temporal distribution of seabed mineral resources and improving the predictive ability of seabed polymetallic ore district can provide support for the exploitation of the resources in the "area". It is the main developing direction in the future to further reveal the three-dimensional pattern of hydrothermal deposits, make delineation of the ore deposits, improve the evaluation technology for resource potential, and set up the geological model for better understanding of seafloor hydrothermal sulfide deposits.
