【摘要】 CO2在金成矿过程中的作用在于：（1）矿源层中金的活化并转化为溶解金；（2）在成矿流体迁移中，CO2不仅可以携带金，而且是使金保持溶解状态的缓冲剂；（3）CO2在溶液中含量变化是金沉淀富集的重要因素．可见，CO2在金的成矿过程中起到极为重要的作用，并可作为找矿的主要指标．更多还原

【Abstract】 During the course of auriferous ore-forming,CO2’s function lies in. (1)activate the gold in the source bed and convert it into the gold in the ore nuid; (2)In the ore nuid moving process,CO2 not only takes Au but also has the buffereing unction of keeping the gold soluble andl (3)As Au mves into the ore-forming fracture in solute state, the change of CO2’s content is the major factor for the gold’s precipitation and enrichment. Therefore, CO2 is the most important factor in the auriferous ore-forming process,and can be served ac an important in dev of prospection and exptoration. CO2CO2.更多还原
