    The Taihua greenstone belt, with a length of 700km, consisting chiefly of a series of volcanic-sedimentary rocks of late Archaean Taihua group with an isotope age of 2600m. y., is located on the south-western margin of the north China platform. This series of rocks has been metamor phosed into greenlandite-hornblende facies. In Wuyang, komatiite has been developed to associate with oceanic tholeiite. This rock suite, with a high abundance of Au-Ag, formed a tight linear fold, in which fractures were well developed. Magmatite is mainly composed of basic volcanic rocks and granite. Gold deposits are occurred in the northwestern section of the greenstone belt. chiefly in the fractures of the axis of a compoundanticline striking approximately to the eastwest direction. Two types of gold deposits are recognized: 1—auriferons quartz; 2—goldbearing altered rocks. Gold mineralizations are developed in metamorphic rocks underlying the Taihua group with distinct stratabound feature. Ore minerals are complex in constituent, varied in fabric and uneven in tenor distribution. The mineralization of gold is multiple both in their mineralization of gold is multiple both in their mineralization period and stage.The ore lead isotope is the ancient weak anomalous lead with a model age of 700-900m. y.The gold deposits,granites and rock series of Taihua group have a similar sulfur isotope ratio but their ages are quite different. This fact shows the heredity and the strata feature of sulfur isotopes. From the isotopic constitutions of hydrogen and oxygen a metamorphic water feature is shown. The mineralizing fluid came from the Taihua group. The mineralization pattern is: volcanic-sedimentary-regional metamorphic-migmatitic-dilatancy-reformation-superimposed. Four prospect areas have been suggested by the author.

    太华绿岩带位于华北地台西南缘,长约700公里,由晚太古代太华群火山—沉积岩系组成,其同位素年龄约26亿年,已变质到铁铝榴石角闪岩相。在舞阳发育有与大洋拉斑玄武岩共生的科马提岩。这套岩系金、银丰度高,形成紧密的线状褶皱,断裂构造极为发育。岩浆岩以基性火山岩和花岗岩为主。金矿分布于该绿岩带的西北段,主要产于近东西向的复背斜轴部断裂中。金矿化类型有含金石英脉型和含金蚀变岩型。金矿化主要赋存于太华群下部变质岩中,具明显的层控特征。矿石成分复杂,组构多种多样,金品位不均匀。金的成矿作用具有多期性和多阶段性。矿石铅同位素为古老弱异常铅,模式年龄为7~9亿年。金矿床,花岗岩和太华群的硫同位素组成相似,但它们的年龄相差甚远。这显示了硫同位素的继承性和层控性。氢、氧同位素组成显示变质水特征。成矿流体来自太华群。成矿模式:火山—沉积—区域变质—混合岩化—扩容成矿—改造—叠加作用。作者提出四个成矿远景地段。

    The geological characters, material composition and texture-structure characters of the gold ore bodies and the occurence of gold are systematically discussed, and the enrichment regularities and the mineralization of the gold deposits are also summarized from three types of gold deposits, i.e contact-fragmentation zone type, gossan type and silicification-fragmentation zone type.
