【摘要】 金厂峪金矿床为多体系复合控制的矿床,发育在太古界变质岩系中,由一组密集的北北东向挤压应变带——破片岩系,控制矿带展布,矿体主要分布在条带状分异岩内。矿带、矿体和矿脉的产出状态与破片岩系紧密相关,成矿地质年龄至少发生在17亿年前,动力变质分异作用为本矿床的成因。本文从三个方面讨论了矿床成因问题:(一)不同构造体系具有不同的成岩成矿作用;(二)构造复合控制成矿作用;(三)小型及微型构造控矿。更多还原

【Abstract】 The characteristics and concentration regularities of Jinchangyu gold ore deposit,one of the five major gold ore diposits in China,are discussed under the guidance of Geomechauic theory and Prof.Yang Kaiqing’s theory of tectonic diagenesis and minerogenesis.The subject that the different structural systems have different diagenesis and minerogenesis is discussed.The palaeomeridional tectonic system is the leading diagenetic and minerogenetic system of the gold ore,while the latitudinal Malanyu anticlinorium tectonic system of Yanshan phase has controlled the occurrence location of the gold ore.Jinchangyu xi-type structure is the tectonic conditions of the concentration of the gold ore.The regularities of ore-control and minerogenesis of the tectonic system is described,and the relationship between minor or micro structures and mineralization enrichment is summarized.更多还原
