| 摘 要： | 通过二道沟金矿区火山—侵入杂岩、构造、矿床的研究,认为成矿与早白垩世斑状花岗间长岩同源;矿脉与岩脉、爆破岩伴生,时空关系密切;结合矿石、矿物、测温资料,确认二道沟金矿为岩浆中温热液金矿床。

| Abstract: | The Erdaogou gold deposit is a part of Erdaogou-Jinchanggouliang gold province in the west of Liapning Province.The basement rocks of the area are Arche-an Jianpin Group metamorphic basic-intermadiate volcanic rocks. The Meso-zoic volcanic-intrusive complex associated with gold mineralization is controlled by two northwest striking abyssal faults which are the Lingyuan-Beipiao fault and Jianpin-Mahugou one respectively.The host rocks of gold lodes are volcanics(in Erdaogou gold deposit) and Arc-hean metavolcanic rocks (in Jinchanggouliang gold deposit)accompanying with sub volcanics and explosion-breccias,which are distributed radiatingly around the por phyritic granodiorite(121.5 Ma of K-Ar age).It has been proved by the geology and geochemistry of the deposit that the Erdaogou gold deposit is of magmatic hydro-thermal orig'in and cogenetic with the porphritic granodiorite. |
