Redox conditions of formation of the Priiskovy massif rock and their metallogenic consequences (South Sikhote-Alin, Primorye)

A key discovery reveals that the Priiskovy massif's amphibole granodiorites, formed during the Cenomanian period (96.91 ± 0.88 and 96.5 ± 1.2 Ma), exhibit distinct redox conditions influencing metallogenic patterns in South Sikhote-Alin, Primorye. The study identifies that magnetite-series rocks under oxidizing conditions are associated with gold deposits and polymetallic mineralization, while ilmenite-series rocks under reducing conditions host tin deposits and occurrences. This spatial distribution explains the localization of ore deposits within the massif, providing insights into the geological processes governing mineralization in this UNESCO World Heritage Site.
