英文摘要	Exhalative mineralizations are frequently associated with various types of exhalites that often provide important evidence for ore genesis. The southern segment of the Da Hinggan Mountains is a well-known tin-polymetallic metallogenic belt of North China v here Jurassic-Cretaceous volcanic-plutonic rocks are widespread. Based on this fact, most of the ore deposits were regarded as epigenetic hydrothermal deposits in genetic connection with the Mesozoic magmatism. However, nearly 90% of the deposits occur in Permian strata implying a close relation between mineralization and Permian strata. Case studies were made on the Huanggang Fe-Sn deposit and the Dajing Sn-polymetallic deposit. In combination with geochemical data, detailed geological, fabric, petrographical and mineralogical, studies on the exhalites associated with ores demonstrated that subaqueous exhalative mineralizaiion did occur during the basin evolution at the Permian time in the southern segment of the Da Hinggan Mountains, which is ignored and poorly understood, but might be as important as the hydrothermal mineralization connected with the Mesozoic magmatism. The stratiform skarns in the Huanggang deposit presents a peculiar example of exhalites. The siderite-sericite chert in the Dajing deposit, regarded as Mesozoic rhyolite porphyry before this study, is a new type exhalite formed in a lacustrine basin and closely associated with sulfide ore characteristic of complex metal assemblage of Sn-Ag-Cu-Pb-Zn. Exhalite is apparently one of the most important petrological evidences for exhalative mineralization.
