关于利用包裹体成分资料计算成矿物质搬运形式的讨论

DISCUSSION ON THE CALCULATION OF TRANSPORTATION FORMS OF ORE-FORMING SUBSTANCES USING DATA OF FLUID INCLUSION COMPOSITIONS

本文讨论了利用包裹体成分资料计算成矿物质的搬运形式问题。本文认为利用此法计算出来的成矿物质的搬运形式仅为真溶液中可溶性物质的搬运形式,并不是成矿物质的全部搬运形式。并认为在计算活度系数时德拜-休克尔方程只能用于溶液离子强度小于0.05的情况下,当溶液离子强度大于0.05时,宜用平均盐法。

In the present paper transportation forms of ore-forming substances calculated using data of fluid inclusion compositions are discussed. In the author's opinion the transportation forms of ore-forming substances calculated by this method only represent the soluble matters in the ionic solutions and do not indicate the all transportation forms existing during the oreforming processes. The Debye-Huckel equation can be used only in the case of inoic strength<0.05 while the mean salt method can be used in the case of ionic strength>0.05 for the determination of activity coefficient.
