本文介绍了俄罗斯东北部南奥莫朗金-银矿床的地质特征,包括矿床的深部构造特点、矿床构造、矿体形态、矿石物质成分及矿化分布规律等。该矿床产在亚诺科雷马地槽系内的奥莫朗地块内;中生代的构造-岩浆活化作用对成矿有重要作用;金-银矿化受长期活动的SN向深断裂及与其交切的NE向断裂所形成的构造结所控制。这一类型矿化产出的大地构造环境与俄罗斯东北部鄂霍茨克-楚克奇地区已知的火山成因的金-银矿化显著不同,因此可以另一种观点来评估该地区中生代褶皱带和中间地块的成矿潜力。
This article describes the geological features of the South Omoor Au-Ag deposit in northeastern Russia, including the deep structural features of the deposit, the structure of the ore deposit, the ore body morphology, the ore composition and mineralization and distribution. The deposit is located within the Omalang block in the Yanoccolacia trough; Mesozoic tectono-magmatic activation plays an important role in metallogenesis; gold-silver mineralization is affected by long-term SN trending faults and The intersection of the NE and the fault structure formed by the junction control. The tectonic setting of this type of mineralization is significantly different from the gold-silver mineralization of the known volcanic origin of the Okhotsk-Chuchic region in northeastern Russia, so another view can be given to assess the Mesozoic fold Belt and the middle of the metallogenic potential of the block.
