【摘要】 河北省灵寿县土岭、石湖金矿赋存于太古代阜平群变质岩系中。矿体严格受构造破碎带制约,控矿构造具有多期性、复合性特点。岩浆岩发育,麻棚岩体属I型花岗岩,其金的丰度值为9.7ppb。硫、碳、氧和铅同位素特征反应成矿热液来源于岩浆岩。黄铁矿中Co/Ni为2.59,Au/Ag<0.5。成矿温度190～373℃。石英包裹体成分中Cl^->F^-,Na⁺>K⁺。金可能以[AuCl₂]^-、[AuCl₄]^-或[AuS]^-、[AuS₂]^-等络合物形式迁移。太行山区土岭、石湖金矿床为岩浆期后热液脉型金矿床。更多还原

【Abstract】 Tuling and Shihu gold deposit in Lingshou county,Hebei province occurred in metamorphic unit of Archean Fuping group.The ore bodiies are spatially controlled by structural shatter zone. The fracture controlling ore body have characteristics of multiple stages and composite as well as long time activity. The magmatic rock is very abundant. The Mapeng magma body is I-type granite. Its gold abundance value is 0.0097 ppm.Sulfur, Carbon,Oxygen as well as lead isotopes indicate that ore-forming fluid were derived from the magma rock.The Co/Ni ratio of pyrite is 2.59; The Au/Ag ratio is less than 0.5; the ore-forming temperature is about 190-373℃; Cl is more than F-,and Na+ is more than K+ in composition of quartz inclusions. These indicates that gold was probably transported as[AuCl2]-, [AuCl4]-, or[Aus]-in hydrothermal solution.Tuling,Shihu gold deposit in the Taihang mountain region is of vein-type gold deposit of post-magmatic hydrothermal.更多还原
