| 摘 要： | 冀东金厂峪金矿产出的地质背景属于太古宙花岗岩—绿岩带构造体制,在与国外太古宙绿岩带镁铁质岩石中石英脉型金矿进行地质对比后,认为该金矿属于活化绿岩带金矿。在研究矿床地质特征、地球化学特征、成矿作用特点和成矿时代等基础上,认为矿质来源于地壳深部,并提出了金厂峪金矿床的两期成矿作用模式。

| Abstract: | The Jingchangyu gold deposit is well known as the largest gold deposit in Eastern Hebei province, China This gold deposit has been mined about one hundred years, its detail geologic prospecting was made in 1960's, and genesis studied in 1970's. The following genetic theories are proposed i.e.magmatic hydrothermal genesis, metamorphermal genesis, migmatitic hydro-thermal genesis and dynamical metamorphic genesis. It is believed that the gold deposit belongs to activated greenstone belt, as compared with quartz vein type gold deposit, and with some mafic rocks of the Archean greenstone belt in the world. Based on study on geology, geochemistry mineralization, metallogenetic epoch and so on, it is indicated that the minerals were derived from the deep crust. Meanwhile, the two-stage minerlization is proposed in Jin. changyu gold deposit. |
