| 摘 要： | 夏塞地区是西南三江(金沙江、澜仓江、怒江)地区东缘的一个重要成矿带，带内银、锡矿产责源十分丰富。本文认为其成矿物质来源于花岗岩体和地层，构造和岩体是区内的主要控矿因素，地壳演化与成矿作用关系十分密切，矿床类型为分布于岩体内接触带的矽卡岩型矿床和分布于岩体外接触带的热液型矿床。

| Abstract: | Xiasai region is situated in the east of the Lancang-Nujiang-Jinsha rivers metallogenic belt and rich in Ag and Sn mineral resources. Ore material was derived from granitoids and strata. Ore-formation was in close relationship with crustal evolution. Ores are controlled by structures and intrusions. Skarn deposits in endocontact and hydrothermal deposits in exocontact predominate. |
