摘要
基于热液矿床(尤其斑岩型矿床)发育大规模裂隙及各类脉体的地质事实,受前人对斑岩矿床裂隙研究的启发,对安徽黄山桃溪地区发育的大规模裂隙带开展野外地质调查,对裂隙中充填的石英硫化物脉采样测试,发现Au、Ag、Pb、Zn等成矿元素含量均达工业品位,且As、Sb、Bi等前晕元素高度富集。结合区域成矿地质背景,推断桃溪裂隙带下方或附近可能隐伏与岩浆侵入有关的金及多金属矿床,桃溪地区值得进一步开展地质矿产调查工作。
On the bas is of the fact that large-scale f ractures often occur in hydrothermal depos i ts , especial in porphyry deposits, along with previous studies of the fissure systems of porphyry deposits, authors carried out field geological survey in massive fissure zones in the Taoxi area and collected samples of quartz sulphides filling in fissures. The result shows that the elements of Au, Ag, Pb, Zn have reached the industrial grades, and halo elements such as As, Sb, Bi are highly enriched in this deposit. Combined with the regional metallogenic geological background, it can be inferred that gold-polymetallic deposits may be concealed under or adjacent to the fissure zones. Therefore, further exploration is worth of undertaking in fissure zones of the Taoxi area.
