| 摘 要： | 在野外地质研究的基础上,采用地球化学热力学方法研究了Cu、Ag的迁移形式。研究结果表明,铜在热液中主要以CuCl42-、Cu(H2O)42+、Cu(S2O3)46-、CuS46-、Cu(HS)42-、Cu(SbS3)410-形式迁移;银在热液中主要以AgCl2-、Ag(S2O3)23-、Ag(HS)2-、AgS23-、Ag(SbS3)25-形式迁移。铜银矿床是在含矿热液物理化学条件发生改变的情况下铜银化合物发生解析作用而成。

| Abstract: | Based on geological field investigation d,this paper deals with the displacement forms of Cu and Ag in ore-forming fluid by Thermodynamics of Geochemistry.It turns out that: Cu in the solution was transported mainly in the form of CuCl42-,Cu(H2O)42+,Cu(S2O3)46-,CuS46-,Cu(HS)42-and Cu(SbS3)410-;Ag in the solution was transported as AgCl2-,Ag(S2O3)23-,Ag(HS)2-,AgS23-and Ag(SbS3)25-;these species were precipitated from the solution when physicochemical conditions,such as T,P,pH,fO2 and fS2,were lower,and thereafter the deposits were formed. |
