摘　　要：本矿床成矿期次有4次,以第1和4期次为主。大量数据显示:第1期次成矿过程萤石形成温度为240～121℃,平均176℃,属中—低温、以低温为主的热液成矿作用;第2期次成矿全过程的温度为1 221～169℃,平均734℃,属高温气液蚀变成矿作用,萤石在中—低温阶段形成;第3期次成矿过程萤石形成温度为168～123℃,平均142℃,属低温热液成矿作用;第4期次成矿过程萤石形成温度为246～115℃,平均150℃,属中—低温、以低温为主的热液成矿作用。There are 4 mineralization periods in the Bamianshan fluorite deposit,among them main periods are 1st and 4th.On great deal of datum,conclusions are followed：The temperature area is 240～121℃ and average temperature is 176℃ of fluorite-forming in first mineralization period that is middle-low temperature that mainly is low temperature thermal mineralization process.The temperature area is 1221～169℃ and average temperature is 734℃ of thermal fluid in second mineralization period that is alteration-mineralization-process of high-temperature gas-fluid and fluorite forms in the middle-low temperature stage.The temperature area is 168～123℃ and average temperature is 142℃ of fluorite-forming in third mineralization period that is low temperature thermal mineralization process.The temperature area is 246～115℃ and average temperature is 150℃ of fluorite-forming in fourth mineralization period that is middle-low temperature that mainly is low temperature thermal mineralization process.
