Petrophysical Characteristics of the Intrusive Complexes of Different Age of the Gamow Peninsula (Southwestern Primorye)

Abstract

The petrophysical data on the granitoids of the Gamow Peninsula are presented and compared with those of the granitoid complexes distributed on the adjacent territory. The physical properties of the Late Permian and Early Jurassic granitoid complexes are considered. Granitoids of different age sharply differ in petrophysical properties. The Late Permian granitoids developed on the Gamow Peninsula have higher density and lower magnetic characteristics relative to the same rocks distributed on the adjacent continental territory. It is established that the petrophysical properties of the Early Jurassic granitoids are similar to those of one phase of the Late Permian granitoids. The simultaneous formation of these complexes is proposed.
