| 摘 要： | 河北省石湖金矿属于黄铁矿硫化物型金矿,具有多期次成矿的特点.但金的主要成矿阶段与硫化物的大量析出阶段在时间上基本一致.硫化物及成矿热液中的硫来自深熔花岗质岩浆.从微观结构和晶体学理论上对金的赋存机理进行了讨论.该矿区金的成色较低的事实,说明了硫化物的发育程度直接影响着金的成色.推断石湖金矿是在多期次成矿的晚期才大量富集的.

| Abstract: | Shihu gold deposit in Hebei Province, belonging to pyrite sulfide type,is characterized by multistage mineralization,but the main stage of mineralization is almost coincident with the mass separation of sulfideThe sulfur in sulfide and mineralizing hydrothermal solution is derived from anatectic granitic magma.The occurrence mechanism of gold is discussed on the basis of micro texture and crystallographyThe fact that the fineness of gold in the deposit is low suggests that the development degree of sulfide has in fluenced the fineness of goldThe gold is enriched in large amounts only in the later stage of mineralization |
