摘要
紫金山高硫浅成低温热液型铜金矿床以一套独具特色的由地开石、明矾石组成的高级泥质蚀变和由硫砷铜矿、蓝辉铜矿、铜蓝组成的铜矿物组合为特征。本文根据矿床的蚀变矿物和矿石矿物组合及矿物的相互关系，着重应用热力学的原理与方法研究矿床形成的物理化学条件。认为形成这一类型矿床的流体是一种高氧逸度、高硫逸度的中低温酸性流体。
The paper focuses on the metallogenic physicochemical conditions of the Zijinshan coppergold deposit in Fujian Province.The Zijinshan copper-gold deposit is the high-sulphur epithermal deposit,which is characterized by both the high argillaceous alteration of dickite and alunite and the copper mineral association of enargite, digenite and covellite.Based on the altered minerals,mineral association and mineral correlation of the Zijinshan copper-gold deposit,the author made an emphatical discussion on the physicochemical conditions of forming the deposit by a thermodynamical mechanism.It is concluded that the fluid forming this type of copper-gold deposit is one high oxygen and sulphur fugacity and low-to-moderate temperature acid fluid.
