Alteration-mineralization zonality of the Teploe 2 and Intruzivnoe molybdenum prospects in the Djetsky ore cluster, Eastern Sayan

Molybdenum mineralization in the Eastern Sayan is represented by the stockwork, vein, and skarn types. The article is devoted to molybdenum ore occurrences of the Dzhetsky ore cluster of the Sisim-Divnogorsk minerogenic zone, that are characterized by the stockwork type mineralization. The Dzhetsky ore cluster is located 160 km northeast of Abakan and 150 km south of Krasnoyarsk. The study included investigations of the host rocks, ores, and ore-accompanying metasomatic alterations; their mineral assemblages; and the morphological types, relationships, and spatial distribution of the ore segregations. It has been demonstrated that the alteration-mineralization zonality of the Teploe 2 and Intrusivnoe molybdenum prospects of the Dzhetsky ore cluster is represented by the propylite type metasomatic alterations that are superimposed in the central segments of the ore occurrences by veinlet silicification bearing copper-molybdenum mineralization.
