| 中文摘要: |
| 胶东东邓金矿产于花岗岩体内,该岩体发育弥漫式钾长石化,并在矿脉附近形成大粒钾长石脉和石英脉矿化体,广泛的蚀变使钾化花岗岩内金属矿物稀少,而控矿构造中形成块状—稠密浸染状含金硫化物,从而使矿脉与围岩间形成显著的物性差异。实践证明,在这种条件下可以采用单一极化率异常结合地质成矿条件,即可完成石英脉型和蚀变岩型金矿脉的成矿性评价,获得工业金矿体。 |
| 英文摘要: |
| Dongdeng gold deposit locates in the granite which developing K-metasomation penetrately, then forming K-feldspar vein and quartz vein gold ore body. The broadly alteration subtracts the metallogenic of the granite and forming block-dense disseminated sulfide minerals in ore-control structures, which forming obvious physical property differences between the orebodies and their wallrocks. In this condition, depending on the singlepolarizability anomaly and the geology conditions,the metallogenic evalution of the ore potentiality discrimination of quartz vein type and the tectonic-altered rock type gold deposit can be made, which will be helpful for finding industrialized gold orebodies. |
