Large-scale tin-polymetallic ore deposit with Sn, Cu, Pb, Zn, Ag and minor elements such as Co and In, hosted by rocks of the Upper Permian Linxi group (terrigenous lacustrine sedimentary rocks, consisting of sandstone, slate, pelitic-silty slate, medium-to fine-grained graywacke, siderite nodule- and P-siderite nodule-bearing siltstone, and marl), in the southwest part of the Huanggang-Wulanhaote metallogenic belt. Orebodies are mainly developed in the upper part of the marl layer and below the P-bearing horizon. Multiperiodic activities of the host structures system led to a multistage mineralization. Four stages are recognized in the main mineralization: 1) cassiterite-arsenopyrite-quartz stage, 2) cassiterite-sulfide (or Cu-polymetallic mineralization) stage, 3) massive pyrite stage, and 4) galena-sphalerite stage. Wallrock alterations are silicification, sericitization, sideritization, chloritization, tourmalinization, dolomitization, calcitization and fluoritization.
