Abstract
The structures of the volcanic seamounts of the Atlantis-Great Meteor group, as well as areas of the archipelagos of the Cape Verde Islands, the Canary Islands and the Azores are analyzed. Their simplest type is a cone-like structure with one summit (Maio seamount). A more complex type consists of two closely spaced volcanic edifices (Nola seamount). The seamounts were also formed as a result of the activity of a central-type volcano and a fissure system (The-Paps seamount). A more complex morphology is presented by the mountains that were formed as a result of the activity of an underwater volcano of the central type, which was combined with the activity of three to four radial fissure volcanic systems (the Tropic seamount). The seamounts were also formed only during fissure eruptions (the Condor seamount, the Cadamosto seamount). These are ridges, tens of kilometers long without a clearly defined summit. All above types of seamounts, with their rise above sea level, subsequent abrasion and subsidence lead to the creation of flat-topped structures (guyots) (the Senghor seamount).
期刊介绍：
Russian Journal of Pacific Geology publishes the results of research on the Earth crust and mantle composition and provides articles on the geological structure and patterns of distribution of mineral deposits in the Pacific Ocean, marginal seas and continental margins. It discusses the topics of stratigraphy, sedimentology, magmatic activity, and seismicity. The journal deals with the problems of lithosphere plates tectonics, and offers the results of neotectonic, geomorphological, geodesic, environmental and mining studies in the Pacific region. The journal accepts theoretical, methodical and philosophical articles covering general issues of geology, geophysics, geochemistry, geoecology and mining. The journal also publishes critical notes and comments, and reviews.
