Cretaceous radiolarian fauna from the Kiselyovsky subterrane, the youngest accretionary complex of the Russian continental far east: Paleotectonic and paleogeographic implications
Abstract The Kiselyovsky subterrane is the northeastern section of the Kiselyovsko‐Manominsky terrane, a distinguishable tectonic unit in the north of the Sikhote‐Alin Range. The terrane has been treated as part of the accretionary wedge belonging to the Khingan‐Okhotsk active continental margin, bu...
