- Abstract
Trench and borehole sampling data were used to investigate the composition of the Au mineralisation and the metasomatically altered rocks at the Zolotoye deposit in Russia. The data show the presence of mineralised zones 1-28 m thick with vein/veinlet silicification and with an Au grade of 1.2-5.8 g/t, and metasomatic zones with a grade of 0.2-2.8 g/t Au at intervals of 2-47 m. U-Pb and Rb-Sr dating indicate two phases of beresitisation at 698-720 and 555-600 Ma. The mineral compositions of Au-bearing metasomatites within primary and oxidised ore zones include pyrite, arsenopyrite, magnetite+haematite, anatase, quartz, albite, chlorite, calcite, muscovite, kaolin+halloysite, limonite and goethite., Trench and borehole sampling data were used to investigate the composition of the Au mineralisation and the metasomatically altered rocks at the Zolotoye deposit in Russia.
