| The territory of Nemichan Mineral District is perspective for its gold and silver resources, and its geologic structure is examined in this paper. It contains a detailed mineralogic description of the Verkhnegayskoe occurrence, that is the best one geologically studied. The processes of a two-stage mineralization and metamorphism-related ore redistribution are described. In addition to this, three more objects of geological interest are shortly presented from viewpoints of their geological structures. The authors use the obtained information as a basis to conclude about volcanic and volcanic-plutonic characters of ore deposits under consideration in this paper. |
