Abstract Northwest Salair Ridge, is one of the oldest alluvial gold mining regions; it is located in the western part of the Altai-Sayan folded area. The placers localized along the Kharuzovka and Kamenka-Barabanovsky creeks (the right-branch of the Suenga River) were chosen for investigation. The only bedrock deposit in the study area is the Novolushnikovsky gold deposit located in the Suenginsky placer field of the Egoryevsky district. The source of gold supply for the Kharuzovka and Kamenka-Barabanovsky placers spatially related to the hypothetical continuation of the type II’ ore zones of the Novolushnikovsky deposit. The composition of gold grains derived from placers was determined based on a representative collection. A distinctive feature of native gold from type II’ ores is unusually high content of Hg, up to 20 wt%. The composition of gold grains from studied placers shows that the average Hg content is 1.5–5 wt%. However, there is a group of Hg-rich placers (

来自 Kamenka-Barabanovsky 和 ​​Kharuzovka 冲积砂矿(俄罗斯西西伯利亚西北 Salair Ridge)的原生金:类型特征和可能的基岩来源

摘要 西北塞莱尔岭,是最古老的冲积金矿区之一;它位于阿尔泰-萨彦褶皱区西部。选择沿 Kharuzovka 和 Kamenka-Barabanovsky 小溪(苏恩加河的右支流)定位的砂矿进行调查。研究区唯一的基岩矿床是位于 Egoryevsky 区 Suenginsky 砂矿场的 Novolushnikovsky 金矿床。Kharuzovka 和 Kamenka-Barabanovsky 砂矿的黄金供应来源在空间上与 Novolushnikovsky 矿床的 II' 型矿带的假设延续有关。来自砂矿的金颗粒的组成是根据代表性集合确定的。来自 II' 型矿石的天然金的一个显着特征是汞含量异常高,高达 20 wt%。来自研究砂矿的金颗粒成分表明平均汞含量为 1.5-5 wt%。然而,有一组富含汞的砂矿(
