Structure and evolution of the Badzhal volcano-­plutonic belt (Far East, Russia)

The largest element of the Songhuajiang-­Badzhal volcanic-­plutonic system, the Badzhal volcanic­-plutonic belt occupies the central position therein. Its structural elements are volcanic troughs, grabens, ring and linear faults. The volcanic-­plutonic belt originated in the Aptian as a system of grabens, infilled by molasses and alkaline basaltoids, resulting from the left-­lateral motion along the faults forming the “horse tail” termination of the Tan Lu fault system. Upwarped doming and dyke emplacement into the cracks of the dome completed the evolution of the belt in the Maastrichtian.
Keywords: the Badzhal volcanic-­plutonic belt, volcanic troughs, grabens, strike­slip duplexes.
