Abstract

The use of morphostructural analysis and cosmogeological interpretation methods by the working with relief digital models (3D) which were created in the Google Earth Pro program based on the global bathymetric databases and maps (GEBCO_2014, GEBCO_2022 Grid) made it possible to obtain fundamentally new information on the qualitative and quantitative characteristics of the Mid-Pacific Mountains and structural elements of adjacent areas of the ocean floor. It was been established that the considered mountains are represented by compound complexes of ring and linear groupings of abraded paleovolcanic edifices and other focal structures that form relict magmatic swells and underwater mountain ridges, respectively. The parameters, morphological features, and basic regularities of focal structures of different sizes and location of occurrence depths were detected; the network of fracture zones and block morphostructures of the region were briefly characterized. The main factors and mechanisms of mountain formation are associated with mantle diapirism phenomena and scale basaltoid volcanism, which occurred in an impulsive regime throughout the Cretaceous.
