摘要
The migrating regularities and zoning features of ore-forming elements, "source bed" problem of Danchi metallogenic belt is demonstrated by comparing the regional stratigraphic geochemical data. The Major elements, trace elements, environmental parameter, alteration-mineralization superpositioin factor of hydrothermal sedimentary rocks in Dachang ore-field are studied for illustrating the features of hydrothermal sedimentary mineralization and establishing metallogenic mechanism of Danchi hydrothermal sedimentary polymetallic belt.
