Igneous Complexes of the Orochenka Caldera of the East Sikhote-Alin Belt: U–Pb (SHRIMP) Age, Trace and Rare Earth Element Composition, and Au–Ag Mineralization

Geology

Abstract

New data are presented on the geology and composition of volcanic and intrusive rocks of the Orochenka caldera, which is located in the western part of the East Sikhote Alin volcanic belt. The SHRIMP and ICP MS age of zircons of volcanic and intrusive rocks, respectively, and the composition of the volcanic rocks allow comparison of these complexes with volcanic rocks of the eastern part of the volcanic structure. New data indicate the period of transition between subduction to transform regimes.
