Deep Structure of the Lithosphere along the Spassk-Dalniy–Zerkalnaya Bay Geotraverse Based on Multidiscipline Exploration Data

The article demonstrates the possibility of joint interpretation of seismic, density, magnetic, and geoelectric models of the deep structure of the lithosphere along the Spassk-Dalniy–Zerkalnaya Bay geotraverse. Seismic and density boundaries form the main structural framework of the integrated model of the lithosphere. Magnetic heterogeneities map the elements associated with magmatism. The electrical model reflects the most recent processes of matter redistribution. The resulting integrated geophysical model demonstrated that for the identified terranes on the surface and most of the faults separating them, the structural style is well expressed only within the upper and middle parts of the crust to a depth of 10–20 km. The lithosphere of the Khanka superterrane retains its structure both in the crust and mantle. Structures of the crust and upper mantle of the Sikhote-Alin orogenic belt are different and associated with each other through highly conductive areas and zones.
