This book is a new approach in the development of global tectonics. It deals with a new variant of the Earth's expansion concept: the model of 'eduction', i.e. of lifting up the mantel material onto the Earth's surface in the active margins of oceans and non-closed character of the mantle currents. The author developed a thorough and comprehensive scientific scenario of tectonic evolution of the Earth using the idea of its radius increase. The most significant and interesting part of the book is a critical analysis of the history of development of plate tectonics. Another remarkable part of the book is the explanation of existing seismicity --- its specific and geographical distribution from the point of view of tectonic evolution of the lithosphere. This book should serve as a trigger for a critical review of contemporary tectonic concepts.
Seismofocal zones: some problems of depth geology and terms used; seismofocal zones and methods for their study; origin of marginal seas; gravity anomalies; heat flow; sediments and basement within the trenches. Critical overview of the subduction concept: development of subduction views; difficulties in explaining the subduction process; ocean-margin accretion and some related questions; structure of the Sunda Trench-Himalayas. Eduction: main premises for the eduction concept; consequences of eduction; interpretation of seismological data - subjects and methods of investigation, education interpretations; gravity anomalies and relief of active margins; geological eduction model - tectonic deformations in an eduction process, evidence of eduction. The mesozoic active margin of north-east Asia: main tectonic features of basement of the Okhotsk-Chukotka; volcanic belt and its perivolcanic area; Oloi-Anyui folded system in western Chukotka - geosynclinal zones, southern margin of the Oloi-Anyui geosynclinal system and Yarakvaam block, structures dividing geosynclinal zones, reconstruction of the geosynclinal system pattern and age of folding; intrust massifs; development of the Koryak geosyncline - Talovka-Main Rise, the northwestern paleocontinental slope, the spatial interrelation of the Koryak geosyncline with more ancient systems, time of the opening, the form of opening, educational basement, age of the sedimentary cover base, complications in the opening of the geosyncline - Velikorechensky through migration of geosynclinal basins and areas of folding after the early cretaceous, migration of volcanism. Deep-sea drilling oceanward from marginal trenches: Wharton Basin - views on origin of Wharton Basin, sedimentary cover in drilling holes, composition of oceanic basement in Wharton Basin; Pacific Ocean: northeastern part of the Pacific, northwestern Pacific, drilling results near Mariana Trench, Cherty Clastic Suite of western margin of the Pacific. Geological history of the Mediterranean region and western Tethys in the cenozoic and mesozoic: opening of the Mediterranean basins - matching the Mediterranean Sea surroundings, Mediterranean basins and original sizes of the East Mediterranean Basin, deep-sea drilling data, history of opening; main structural features of the western Alpine-Himalayan folding belt before the opening of the Mediterranean basins.
