Abstract

The Elegest-Mezhegei, Aptara, and Shivilig forecasted gold ore clusters and the Kharalyg and Irbitei forecasted gold-silver-polymetallic ore clusters were distinguished within the East Tannu-Ola iron-copper-polymetallic-gold ore region, based on examination of historical and new geological, geochemical, and metallogenical data. Subsequently, the Urgailyg, Proezdnoe, and Chumurtuk forecasted gold ore fields were delineated within the Elegest-Mezhegei cluster; the Despen ore field was delineated within the Aptara ore cluster; and the Ovur-Ongesh ore field was outlined within the Shivilig cluster. In addition, the Ulug-Sailyg and Ak-Charinsk gold-molybdenum-copper ore fields were distinguished outside the ore clusters. The article summarizes the investigation history, geological-structural position, geological features, and geochemical specialization of the rocks of the East Tannu-Ola region. Descriptions of the ore clusters embrace peculiarities of their geological structure, ore mineralogy, and native gold, as well as parameters of the gold-sulfide-quartz, goldskarn, gold-containing polymetallic VMS, and porphyry molybdenum-copper mineralized zones. The conclusions highlight the metallogenic epochs and distribution regularities of the gold and gold-containing mineralization within the region studied.

特瓦共和国东坦努—奥拉矿区金矿成矿作用

根据历史和新的地质、地球化学和成矿资料，在东坦努-奥拉铁-铜-多金属-金矿区划分了eleest - mezhegei、Aptara和Shivilig预测金矿群和Kharalyg和Irbitei预测金银多金属金矿群。随后，在鄂尔加里格、Proezdnoe、Chumurtuk预测金矿床圈定在eleest - mezhegei群内;在Aptara矿群内圈定了Despen矿田;Ovur-Ongesh矿田位于Shivilig集群内。此外，乌鲁格-塞利格和阿克-查林斯克金-钼-铜矿田在矿团外也有明显的区分。本文综述了东坦努-奥拉地区岩石的调查历史、地质构造位置、地质特征和地球化学专门性。对矿团的描述包括其地质构造、矿石矿物学和原生金的特性，以及金硫化物-石英、金矽卡岩、含金多金属VMS和斑岩钼铜成矿带的参数。研究结果突出了研究区内金矿及含金矿的成矿时代及分布规律。
