Abstract—This paper focuses on new data for palladium-bearing mineral phases in the ores of the Malmyzh porphyry gold–copper deposit situated approximately 220 km northeast of Khabarovsk in the Russian Far Eas. The Malmyzh area comprises the Early Cretaceous terrigenous sediments, which are intruded by the Albian to Cenomanian diorite and granodiorite stocks. The platinum group minerals (PGM), sopcheite, merenskyite, kotulskite, naldrettite, and arsenopalladinite, were identified during a detailed study of chalcopyrite veinlets at the Freedom site of the Malmyzh porphyry Cu–Au deposit. The relationship with other minerals indicates that these PGM are later than chalcopyrite.

摘要— 本文重点介绍了位于俄罗斯远东地区哈巴罗夫斯克东北约 220 公里处的 Malmyzh 斑岩金铜矿床矿石中含钯矿物相的新数据。Malmyzh 地区包括早白垩世陆源沉积物，这些沉积物被 Albian 到 Cenomanian 闪长岩和花岗闪长岩储量侵入。在对 Malmyzh 斑岩 Cu-Au 矿床 Freedom 矿点的黄铜矿细脉进行详细研究期间，发现了铂族矿物 (PGM)、sopcheite、merenskyite、kotulskite、naldrettite 和arsenopalladinite。与其他矿物的关系表明，这些铂族金属晚于黄铜矿。
