Evidence of late palaeozoic thermalwater metallization in South Yongmei Depression

Abstract

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 double-peak type. Several kinds of hydrothermal sedimentary rocks and the ore-bearing sedimentary formations of copper-polymetals, iron and manganese exist in this region with a zoning feature of the seafloor thermalwater spout sedimentation.
