The Rotational Tectonics of the Agnie–Afanas’evskii Ore Cluster in the Lower Amur Region

Abstract

The geodynamic setting of the Agnie–Afanas’evskaya auriferous rotational structure, genetically related to a transtensional left-lateral duplex zone which was formed against the background of the regional roughly north–south lateral contraction (transpression), is discussed. Regional dislocations are accompanied by local dislocations caused by internal stresses, which account for the details of the structural pattern of the gold deposit. This enables us to forecast auriferous stockwork bodies on a new basis.
