New Data On Ree Distribution In Rocksof Late Paleozoic Gold-bearing And Gold-free Diorite- granodiorite-adamellite Series In The Eastern Slope of The South Urals

摘要

The eastern slope of the South Urals comprises three belts with development of intrusions belonging to the diorite-granodiorite-adamellite series: western, central, and eastern (Fig. 1). The western belt terminates the formation of the Middle-Late Devonian (Frasnian) Magnitrogorsk-Mugodzhary island arc [1]. The central belt corresponds to relict structures of the Middle-Late Devonian marginal volcanic belt [2]. The eastern belt is represented by the Early Carboniferous activation zones of the Transuralian Uplift, the formation of which is related to the ascending mantle diapir [3-5].
