已有的地质、地球物理和地球化学证据表明太古宙Au-石英脉、低温热液Au-Ag和Au矽卡岩成矿流体的主要组分源自岩浆,而且Au、Ag及有关的富美元素也源自岩浆。太古宙Au-石英脉、太古宙Hemlo型、低温热液Au-Ag和Au矽卡岩体系的元素的产出具有重要的共性,表明其具有共同的成因过程。例如,27个元素中,44%(n=12)的元素出现在10个矿床亚类的至少7个亚类之中:Au、Ag、Fe、Cu、Pb、Zn、Hg、Mo、Sb、As、Te和s(9个金属、2个类金属和1个非金属)。加上B和W,52%(n=14)出现在至少5个亚类之中。富集的亲铜/亲铁元素的出现频率很高,达85%(27个元素中的23个)。总体元素(n=31)的出现频率也较高,达74%(n=23)。所有这些主要的亲铜/亲铁元素均富集于太古宙Au-石英脉、太古宙Hemlo型、低温热液Au-Ag和Au矽卡岩矿床之中。如果岩浆挥发分的饱和出现在岩浆硫化物熔体/上悬固体因重力而亏损之后,那么Au、Ag和相关亲铜元素将由于高的硫化物熔体/硅酸盐岩浆的分配系数(10 ̄2~10 ̄4,如Au为3x10 ̄4,Se为10 ̄3)而从岩浆中分离出来。因此可以得出,太古宙Au-石?
The available geological, geophysical and geochemical evidence suggests that the major components of the Archean Au- quartz veins, low-temperature hydrothermal Au-Ag and Au skarn mineralization fluids originate from magma and that Au, Ag and related Euphrates From magma. Archaeozoic Au-quartz veins, Archean Hemlo-type, low-temperature hydrothermal Au-Ag and Au skarn system elements have important commonalities, indicating that they have a common genetic process. For example, of the 27 elements, 44% (n = 12) of the elements appear in at least seven sub-categories of the 10 deposit sub-categories: Au, Ag, Fe, Cu, Pb, Zn, Hg, Mo, Sb, As, Te and s (9 metals, 2 metals and 1 nonmetal). With B and W, 52% (n = 14) appeared in at least 5 subcategories. Enriched pro-copper / pro-iron elements occur at a high rate of 85% (23 of 27 elements). The overall element (n = 31) also appeared at a high frequency of 74% (n = 23). All of these major copper / iron elements are enriched in Archean Au-quartz veins, Archean Hemlo-type, low-temperature hydrothermal Au-Ag and Au skarn deposits. If the saturation of the magma volatiles occurs after the magma sulfide melt / overhang is depleted due to gravity, the Au, Ag and related cupper elements will be depleted due to the high sulphide melt / silicate magma partition coefficient (10 ~ 2 ~ 10 ~ 4, such as Au is 3 × 10 ~ 4, Se is 10 ~ 3) and separated from the magma. It can therefore be concluded that Archean Au-Stones
