Types and physical properties of igneous rocks of Popov Island in Peter the Great Bay of the Sea of Japan.

This paper presents the results of geological and petrophysical research carried out on Popov Island by the Pacific Oceanological Institute of the Far East Branch of the Russian academy of Sciences during 2003-2009. As a result, 7 types of rocks were identified. Their density and magnetic susceptibility have been determined. It was established that the rock types are clearly differentiated with respect to their physical parameters. The identified relationship allows one to use these physical properties, first of all, for the geological interpretation of the gravity and hydromagnetic survey carried out in the surrounding water area of Peter the Great Bay and, secondly, as an additional indicator for igneous rock typification on other islands of the region. Such comprehensive and integrated research was carried out for the first time in this area. The results obtained are important for solving the problem of the structural, compositional, and genetic relationships between the terrestrial and marine structures at the junction zone between the Japanese Basin and the adjacent continent.
