在确定出哀牢山金矿带成矿流体中的硫是金成矿的主要矿化剂的基础上 ,对成矿流体的硫、氦、氩同位素以及与金成矿有关的地质事件进行了系统研究 .研究结果表明 ,哀牢山金矿带各金矿床的成矿流体 ,是富硫的深源高温流体与贫硫的大气成因低温地下水二端元混合的产物 ;富硫深源流体上升加入地壳浅层贫硫流体的过程 ,受喜山早期地壳拉张作用控制 ;哀牢山金矿带金成矿之所以集中在喜山早期 ,主要是通过喜山早期富硫的深源流体上升 ,加入原在该地区浅层断裂中循环的大气成因贫硫流体中 ,从而使这种贫硫的流体转化成富含足够硫进而能够大规模浸取金的成矿流体来实现的 .
On the basis of confirming that sulfur in ore-forming fluid of Ailaoshan gold deposit is the main mineralizer of gold mineralization, the sulfur, helium and argon isotopes of ore-forming fluid and the geological events related to gold mineralization were systematically studied The results show that the ore-forming fluid in each gold deposit of Ailaoshan Mountain gold deposit is the result of mixed two-terminal element of low temperature groundwater with sulfur-depleted deep-source high-temperature fluid and sulfur-depleted atmosphere. The process of shallow sulfur-depleted fluids is controlled by the early Himalayan crustal extension. The reason why the gold mineralization of the Ailaoshan Gold Belt concentrated in the early Himalayan period was mainly due to the increase of sulfur-rich deep-source fluids in the early Himalayan period, The atmospheric recycle of the sulfur-depleted fluid in shallow fractures in the area led to the conversion of this sulfur-depleted fluid into an ore-forming fluid enriched with sufficient sulfur to allow large-scale leaching of gold.
