Indicator and Isotope Geochemical Characteristics of Iron Sulfides from the Golets Vysochaishy Deposit, East Siberia

This paper provides new data on various pyrite and pyrrhotite generations at the Golets Vysochaishy gold deposit, Bodaibo district, Irkutsk Oblast. These generations are distinguished by morphological, geochemical, and isotope (δ 34 S) features. The established features of pyrite generations reflect...

Description
Summary:This paper provides new data on various pyrite and pyrrhotite generations at the Golets Vysochaishy gold deposit, Bodaibo district, Irkutsk Oblast. These generations are distinguished by morphological, geochemical, and isotope (δ 34 S) features. The established features of pyrite generations reflect the evolution of the Golets Vysochaishy deposit. Each pyrite generation is associated with a certain evolutionary stage of Neoproterozoic rocks in the region: (1) diagenesis (610 Ma), (2) catagenesis (570–520 Ma), (3) metamorphism (~450–430 Ma), and (4) tectono-magmatic activation (330–270 Ma). The 40 Ar/ 39 Ar ages of the third and fourth pyrite generations correspond to those of previously determined gold mineralization and granite magmatism.
