Uchaminsky Be–W–Au Ore Cluster in the Regional and Local Structures of the Lower Amur Region

详细

The Uchaminsky ore cluster is located on the Pilda–Limuri watershed in the long-known gold-mining area of the Lower Amur region. It is shown that the distribution of polygenetic and polychronous Be–W–Au mineralization is associated with the northeastern left-lateral strike-slip ore-magmatic tension duplex that was developed in a transtensional regime under general submeridional compression (transpression). The structural, lithological, and magmatic features of the strike-slip duplex are favorable for searching for new large-volume stockwork gold deposits and ore bodies.
