文摘This paper discusses the seafloor thermalwater spout sedimentary activity in South Yongmei Depression according to the following evidences: the Yongmei region was in an extended tectonic environment of metaplateform and locally developed intracontinental rift aulacogen in company with the activity of rich alkali, high potassium volcanics of doublepeak type. Several kinds of hydrothermal sedimentary rocks and the orebearing sedimentary formations of copperpolymetals, iron and manganese exist in this region with a zoning feature of the seafloor thermalwater spout sedimentation.
