摘　　要：双王金矿具有多期多阶段叠加成矿成晕的特点 ,该矿床可分为 4个阶段 ,不同成矿阶段的元素组合是 :Ⅰ (阶段 )—Au ,As,Sb ,Mn ,Ni;Ⅱ—Au,Ag ,As,Sb ,Bi,Mo ,Mn ,Ni;Ⅲ—Au ,As,Sb ,Hg ,Mn ,Ni;Ⅳ—Au ,Ag,As,Sb ,Hg ,B ,Bi,Mo,Mn ,Ni,其中Ⅰ、Ⅱ、Ⅲ阶段为主成矿阶段。单阶段形成的矿体 (晕 )的垂直分带序列是(从上→下 ) :Hg ,B ,Sb ,As→Ag ,As→Bi,Mn→Ni。不同成矿阶段形成矿体 (晕 )在空间上叠加特点是 :从上→下 ,Ⅰ阶段由弱→强 ,Ⅱ、Ⅳ阶段由强→弱。据上述特点建立了矿床的原生叠加晕模式。Shuangwang gold deposit has features of multiphase and multistage superimposed mineralization and halo. This deposit can be divided into four stages. The element association at different metallogenetic stages are as follows:I(stage)—Au, As, Sb, Mn, Ni;Ⅱ—Au, Ag, As, Sb, Bi, Mo, Mn, Ni;Ⅲ—Au, As, Sb, Hg, Mn, Ni;Ⅳ—Au, Ag, As, Sb, Hg,B, Bi, Mo, Mn, Ni. stages Ⅰ, Ⅱ, Ⅲ are considered as the main metallogenetic stages. The vertical zoning sequence of primary halos by single-stage is as follows(from top to bottom):Hg, B, Sb, As→Ag, Au→Bi, Mn→Ni. The features of spacial superimposition of bodyies and halos in different minerallizing stages are as follows(from top to bottom):stage(Ⅰ)from weak to strong; stage(Ⅱ, Ⅲ)from strong to weak. The model of primary superimposed halo in the deposit has been established.
