摘要
本文通过对3、6、8、307号脉矿物中包裹体的研究，得出本区含宝石伟晶岩包裹体是以流体包裹体为主．包裹体的成分主要为CO2，其次为水溶液和一定量的CH4、CO、H2S、SO2．成矿温度主要集中于340～460℃，流体含盐度2．5％～29．5％、成矿压力值为250×105～380×105Pa、氧逸度值较低，为（10－27～10－36）×105Pa，以上参数是含矿岩体的包裹体地球化学特征．
By studying the inclusions of minerals in the veins of number 3. 6. 8 and 307,the authors of this paper conclude that the inclusions in the gem-bearing pagmatite are mainly the fluid inclusions in the area. The components of the inclusions are composed of carbon dioxide (CO2), fluid, methane(CH4),carbon monoxide (CO),hedrogenic sulphide (H2S)and sulphur dioxide (SO2). The temprature of ore-forming ranges from 340℃ to 460℃ ;The salinty of the fluid ranges from 2. 5 to 29. 5 pcrcent of wt. The value of the pressure of mineralization ranges from 250× 105 to 380× 105 pa. The oxyden fugacity (fo2) is relatively lower. It ranges from (10-27to 10-36) × 105pa. The above parameters represent geochemistry characteristics of the inclusions in orebearing body.
