Abstract Sedimentary exhalative deposits (SEDEX) are an important kind of ore deposits, and provide about 60% of the lead and 50% of the zinc in the world. In this paper, based on consulting previous and the latest research achievements, reading relevant literatures and synthesizing the different theories, the authors summarize the ore-forming tectonic setting and geological characteristics and, in combination with S, Pb, H, O and B isotopes, discuss the sources of ore-forming materials and fluids in terms of geochemistry. Based on former metallogenic model, the authors further improve the mineralization mechanism. In the end, this paper describes the new research progress, and gives some suggestions for the existent problems and development trends in the future.
