Fragments of Cretaceous seamounts in accretionary structure of the Kamchatsky Mys Peninsuls (Kamchatka, Russia)

The geological structure of the Kamchatsky Mys peninsula is determined by its position at the junction of major structures in the NW Pacific - the Kuril-Kamchatka island arc, Aleutian island arc and submarine Emperor Ridge. The southern part of the peninsula is composed by the accretionary prism of...
