摘    要:板庙子金矿区主要矿石类型有含金黄铁矿型和含金多金属型,对两类矿石研究表明金赋存于黄铁矿和交代、穿切黄铁矿的黄铜矿中,主要与黄铁矿有关;对矿石中的A u、A g、Cu、Pb、Zn、Co、N i、B i、R b、S r、B a元素进行R型聚类分群,结果为A u B i、A g Zn Cu Co Pb N i、R b S r B a三群;对两类矿石与成矿关系密切的脉岩进行Q型聚类分群,结果表明金—黄铁矿型矿石与辉绿岩、煌斑岩、花岗斑岩有关,金—多金属型矿石主要与二长花岗斑岩、闪长玢岩有关,并与实际地质调查认识一致。由此明确了本矿区中金主要形成于金—黄铁矿阶段,少量形成于金—多金属阶段,随着岩浆由中性向酸性演化,成矿作用由贵金属向多金属矿化转变,并在空间上形成叠加。

关 键 词:金矿区  成矿阶段  微量元素  R型聚类分析  Q型聚类分析

Abstract:There are mainly two ore types in Banmiaozi gold mining area,namely,gold-bearing pyrite and gold-bearing polymetallic type,the research shows that gold occurs both in pyrite and replacement and transverse chalcopyrite which is related to the pyrite,most of gold exists in the pyrite;through R type clustering analysis of Au,Ag,Cu,Pb,Zn,Co,Ni,Bi,Rb,Sr and Ba,the result shows three coalescences by Au Bi, Ag Zn Cu Co Pb Ni and Rb Sr Ba;through the analysis of Q type clustering and vein related with mineralization,the result shows that gold-pyrite type ore is related with the diabase,lamprophyre and granite-porphyry;the gold-polymetallic type ore is related with the monzonitic granite-porphyry and diorite-porphyrite,the result also accords with the cognition from the practical geologic surveying.So the authors defined a conclusion that most gold derives from the gold-pyrite stage,others derive from gold-polymetallic stage,with the magma evolve from neutral rock to acidite,the mineralization evolve from noble metal to polymetale, and forming spatial superpose.
Keywords:gold mining area  metallogenitic stage  microelement  R type clustering analysis  Q type clustering analysis
