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。
The Jinchangyu gold deposit is a multi-system complex controlled deposit that developed in the Archean metamorphic rocks. It is composed of a group of intensive north-east-east compressive strain-fragment rock series that control the distribution of ore belts, Distribution in the zonal divisions. The production status of orebodies, ore bodies and veins is closely related to the fragment rock series. The geological age of mineralization occurred at least 1.7 billion years ago, and the motility metamorphism is the genesis of this deposit. This paper discusses the genesis of the deposit from three aspects: (1) different tectonic systems have different diagenesis and mineralization; (2) structural control of mineralization; (3) small and micro-structure control of ore.
