摘要: 北山北带位于甘肃省西北部,南起于破城山-公婆泉北山一带,北止于中蒙边境;为中朝板块和西伯利亚板块的对接部位。带内金矿化分布广泛,已发现金矿床(点)二十余处。该带研究程度较低,本文就现有的工作成果对北山北带金矿产出的地质背景、金矿成矿特征阐述一些粗浅看法。Abstract: The north belt of Beishan is located in the northwest of Gansu province, it is the matching belt between Sino-Korean and Siberian plates. Gold metallization occurs in the area and more than 20 gold deposits (ore spots) discovered. This paper discusses geological setting and gold metallization feature.
