Abstract

Abstract

The discuss on the topographical environment characteristics of typical modern marine hydrothermal activity regions will be helpful to increase understanding of the modern hydrothermal activity,the distribution rules of its mineral resources and the forming causes and mechanism,etc.The three-dimensional topography figures of major typical hydrothermal regions are drawn on the basis of fielD-measured bathymetric data of the Okinawa Trough and collecting a large number of data on bathymetry,multibeam and seismic profiles of other major typical hydrothermal regions.Through the systematic analysis and contraststudies on topographical environment characteristics of these typical regions,it is found that the hydrothermal activity only occurs under the circumstance of the particular topographical environment,though it distributes widely in the tensional tectonic environment,for inst ance,t he mid-ocean ridges,transform faults zones,back-arc spreading basins and the modern marine craters regions.
