山西堡子湾金矿床黄铁矿标型特征

从成因矿物学及找矿矿物学观点出发，系统研究了堡子湾金矿床黄铁矿的产状，形态，化学成分，热电性质和热爆特征，该矿床黄铁矿富含Co,Ni,As,Ag,Au与W，Cu,Hg,Ag，As，Bi,Ni,Co,Pb相关性较好，构成特征元素组合，与通常认为的与火山－次火山热液有关的明矾石－高岭土型浅成中低温热液型金矿床特征元素及其组合基本一致。黄铁矿空穴型导电性与明矾，石－高岭土型浅成中低温热液型金矿床特征元素圾其组合基本一致。黄铁矿空穴型导电性与As,Au正相关，与Co，Ni呈明显的负相关，P型和N型导电性是由As/(Co Ni)值决定的。利用黄铁矿热电性及热爆特征空间分带与赋矿空间的对应关系进行成矿预测，效果明显。

Typomorphic characteristics of pyrite in the Puziwan gold deposit,Shanxi

Utilizing the theories of minerageny and prospecting mineralogy,we studied the attitude,morphotype,chemical composition,pyroelectricity and thermal explosion of pyrites in the Puziwan gold deposit.The pyrites of the doposit are enriched with Co,Ni,As and Ag.Au has well correlation with Cu,Hg,Ag,As,Bi,Ni,Co,Pb.These have formed the characteristic association of elements which are in coincidence with those of alunite Kaolin type mesothermal epithermal gold deposits related to volcanic subvolcanic hydrothermal solutions. The hole type conductance of pyrite appears positive correlation with As,Au,and appears negative correlation with Co,Ni.The P type and N type conductance of pyrites are dominated by As/(Co+Ni) value.It has great efficiency in metallogenic prognosis by the corresponding relation between the space zoning of the pyroelectricity and thermal explosion of pyrite and host space of ore deposits.
