摘要

俄罗斯最大的Gorevskoye铅锌矿(Gorevsky GOK, Novoangarsky OK)的开发将取决于安加拉多金属矿区，特别是拉索金斯基矿群的前景。在综合分析前人和目前研究的地质和地球物理资料的基础上，预测该区内存在褐铁矿-黄铁矿-多金属(块状硫化物)矿床。矿石定位的主要岩性和地层学标准是由它们局限于上里芬岩potosky套上亚组的高碳黑石英绢云母片岩确定的。在该充填体的顶部，局部发育70 ~ 140 m厚的层状块状黄铁矿多金属矿石。根据PPA数据，岩心铅锌含量从百分之一到百分之几不等，根据ICP-AES方法:0,1 - 3,7 % Pb, 0,1 - 6,4 % Zn, Pb: Zn比为1∶(1 - 10)。

Geology and pyrite-polymetallic mineralization of the forecasted Limonite deposit, Rassokhinsky ore cluster (Yenisei ridge)

The development of Russia’s largest Gorevskoye leadzinc deposit (Gorevsky GOK, Novoangarsky OK) will depend on promising deposits of the Angara polymetallic ore region, in particular, those of the Rassokhinsky ore cluster. Based on the analysis of geological and geophysical information of previous and current studies, a major Limonite pyrite-polymetallic (massive sulfide) deposit is forecasted within it. The main lithological and stratigraphic criterion for the localization of ores is determined by their confinement to high-carbon black quartz-sericite schists of the upper subformation of the Potoskuy suite of the Upper Riphean. In the top of this pack, layered and massive pyrite-polymetallic ores, 70– 140 m thick, are localized. Based on PPA data, lead and zinc content in core varies from fractions of a percent to several percent, based on the ICP-AES method: 0,1– 3,7 % Pb, 0,1–6,4 % Zn, Pb : Zn ratio is 1 : (1–10).
