The effect of magmatic sulfide precipitation on the potential of magmatic systems to produce porphyry-type ore deposits is still a matter of debate. In particular, we need to know whether magmatic sulfide precipitation has an impact on the Cu and Au content of the exsolving magmatic volatile phases and, by this way, on the Cu/Au ratio of porphyry deposits. The Javorie volcano is a perfect place to explore these questions. First, it hosts several Au-only porphyry-type mineralized occurrences which have among the lowest Cu/Au ratios reported in the literature. Secondly, the geology of the Javorie volcano and the timing of porphyry Au mineralization are well established.

斑岩型金矿Javorie火山（斯洛伐克中部）岩浆的起源与演化：来自热压法，熔体包裹体和硫化物包裹体的证据

岩浆硫化物沉淀对岩浆系统产生斑岩型矿床的潜力的影响仍是一个争论的问题。特别是，我们需要了解岩浆硫化物的沉淀是否对溶解岩浆挥发相中的铜和金含量以及斑岩矿床的铜/金比有影响。贾沃里火山是探索这些问题的理想之地。首先，它拥有数个仅含金的斑岩型矿化带，其文献报道的铜/金比最低。其次，Javorie火山的地质学和斑岩型Au矿化的时机已经确定。
