Igneous rocks of the West Sakhalin Terrane of Sakhalin Island

Аннотация

It has been determined that the Rozhdestvenka Formation of the West Sakhalin Terrane composed of Late Mesozoic igneous rocks is a fragment of the accretionary prism of the Rebun–Kabato–Moneron–Samarga island-arc system. Volcanic eruptions, as well as destruction of the Rebun–Kabato–Moneron–Samarga island-arc and the East Sikhote-Alin volcano plutonic marginal continental belt, were the sources of pyroclastic and clastic material entering the sedimentary basin, where the Pobedinsk and Krasnoyarka suites of the West Sakhalin Terrane were formed.
