赋生在花岗岩、混合岩断裂带的中低温银金矿床是我国有前途的银金矿床类型。本文详述了张公岭该类型矿床的矿物共生组合,金、银赋存状态。并据野外、室内资料划分了五个热液阶段,四个矿化阶段。据此提出了该区的找矿标志。 The intermediate-low-temperature silver-gold deposits that were born in granite and mixed rock fracture zones are the promising silver-gold deposit types in our country. This paper details the mineral assemblages, the gold and silver occurrences in the Zhanggongling deposit. According to the field and indoor data, five hydrothermal stages and four mineralization stages are divided. According to this, the prospecting sign of this area is put forward.
