Geosynclines

Geosynclines is devoted to the geosynclines concept, which states that the most elevated parts of the earth's crust—the mountains—had risen by a gigantic inversion of relief from the more depressed regions where they had originated. This book re-examines the concept in light of further geological evidence. The book is organized into four parts. Part I presents a detailed account of the birth and development of the geosynclinal concept. It shows that only the European (Alpine) concept of the geosyncline involves a fundamental palaeogeographical differentiation of mountain chains, and that it is from this standpoint that the American concept must be considered if it is to be placed in a more general framework. Part II attempts to define the geosynclinal concept in the Alpine sense of the term: i.e., in the light of current views on the Mediterranean chains of the Alpine cycle, which are the best documented. Part III collates the information acquired on the various aspects of geosynclines as exemplified by the Mediterranean chains of the Alpine cycle. Part IV discusses the degree to which the ""Alpine"" concept of the geosyncline may be extended in time.
