Structural geology / Структурная геология

Much new information on structural geology has been published since the last edition of this book. Obviously the more significant new data should be introduced into an elementary text. But in order to keep the length within reasonable bounds it would be necessary to eliminate some of the older material. This is not easy to do. Some might be eliminated completely and some might be shortened, but presumably the original text was as concise as possible.As in the past, the principal purpose has been to present the basic principles of structural geology. There has never been a pretense to cover global tectonics, such as the evolution of mountain ranges, continents, and ocean basins. In the second edition I said: “Oceanography ... is discovering many exciting facts about the topography and composition of the floors of the oceans, facts that are already revolutionizing our thinking about the crust of the earth.” But little did I anticipate the full magnitude and impact of these discoveries. However, a synthesis of the tectonics of the ocean basins is beyond the scope of this book. <...>
