金家庄金矿床位于河北省赤城县小张家口超基性岩体最西端,崇礼—赤城深大断裂带南部。该矿床产于超基性岩中的断裂带内,金、银品位较高,具有一定规模。近两年通过开采和进一步工作,获得下列初步认识: 1.金矿床地质特征:该矿床构造活动多期多次,岩浆活动强烈,变质作用、混合岩化作用及热液蚀变普遍发育。矿区内主要地层为太古界片麻岩、变粒岩夹少量透辉大理岩,其上
The Jinjiazhuang gold deposit is located in the westernmost part of the Xiaochangjiakou ultrabasic rock mass in Chicheng County, Hebei Province, and to the south of the Chongli-Chicheng Deep Fault Zone. The deposit is produced in the ultramafic rocks in the fault zone, gold, silver grade is higher, with a certain scale. In the past two years, the following preliminary understanding has been obtained through mining and further work: 1. Geological characteristics of gold deposits: The tectonic activity of this deposit is multi-time and multi-times with strong magmatic activity, metamorphism, mixed rockification and hydrothermal alteration. The main strata in the mining area are Archean gneiss, granulite with a small amount of translucent marble, on which
