摘要
矿床的矿石与围岩具有相同的稀土元素组成,稀土参数和稀土模式也非常接近,且有一致的微量元素比值和分布形式,冷家溪群地层为金的矿源层,金从围岩中被活化和迁移出来,沉淀于断裂破碎带中,形成沉积改造金矿床。
The Huangjindong gold deposit occurs in Middle Proterozoic Lengjiaxi Group the source bed and iscontrolled by a fractured zone,with its REE compositions in ores as same as those in its countryrocks,and with the very same rare earth parameter and pattern.In addition,the ratios and distributionpatterns of microelements for the ores and country rocks of the deposit are also about the same.Thegold mineralizations were activated,and migrated from the country rocks and deposited in the fracturedzone to form this sedimentaryreformed type gold deposit.
