| Summary: | 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 the Kronotsky paleoarc (Khotin and Shapiro, 2006). A significant part of the accretionary complex is comprised by rocks of ophiolite association, namely mantle peridotites, gabbro, dolerites, basalts, hyaloclastites, jaspers and limestones. Our many-year studies showed that some Cretaceous volcanic and sedimentary rocks of the ophiolite complex can represent fragments of an intraplate seamount, which could belong to the Emperor Ridge. |
