Far East Geological Institute FEB RAS Hydrothermalites of Milogiadovo area (South Primorye) and their spatial relation with gold-silver occurrences
We have studied the structure of the massif of secondary quartzites known as «Kosmos» that occurs in the southern part of the East-Sikhote-Alin volcanic belt. E. Marcoux's model was used to explain possible spatial relations of the quartzite massif and a large Milogradovo occurrence of gold-silver mineralization located at a distance of about 8 km from the «Kosmos». The absence of intensive metasomatic alterations («cherty cap in the argillization field») within the ore-bearing area is, probably, due to the influence of the post-ore denudation processes.
