摘要
At the basis of predecessors’s research on the Sedex type deposits, and combining with some of the typical domestic deposits in China, such as Jinding super-large Pb-Zn deposit, Baiyangping deposit, Dachang Sn-polymetallic deposit and so on, the authors sum up geological characteristics of this type of deposits. And they also discuss the types of deposits as sources of metallogenic material and fluid from the geochemitstry aspects of the main, trace elements, rare earth elements and stable elements as well as the rare gas element geochemistry.
