摘要
该金矿床位于外方山断隆与旧县—大章断陷盆地结合部位的东部,是典型的受构造控制的构造蚀变岩型金矿床。构造活动的多期性形成了构造岩的复杂性。多期次成矿导致金矿体在走向上、倾向上都具侧列再现、相互叠加等组合特征;每一期次成矿都表现了各自的地球化学特征和元素组合特征;成矿指示元素在垂向上具有各自的规律性。以上研究成果对本区及类似地区的金矿的地质找矿具有重要的指导意义。
The Dongwan Au deposit lies in the east of the intersection of the Waifangshan fault uplift and the Jiuxian - Dazhang faulted basin. The Au deposit is a typical tectonic - altered rock type one. Multi - stage tectonism resulted in complexity of tectonite. Multi - stage ore - formation resulted in superimposition of geochemical features and element associations. The respective ore-forming indicator elements have individual laws, respectively. The above- mentioned resuits are of importance to searching for Au ores in this region.
