Traité de Géologie

Abstract

THE third fascicule of Prof. Haug's “Traité de Géologie” completes this valuable textbook with an account of the post-Cretaceous formations. The author's treatment of the subject, as in the previous parts, is marked by the special importance given to the varying bathymetric conditions under which different parts and areas of a formation have been laid down. The present volume is also of interest as it presents a modern French classification of the post-Cretaceous rocks. Prof. Haug does not use the term Kainozoic, and does not adopt any one term for these formations. He divides the post-Cretaceous time into three eras: the Nummulitic, the Neogene, and the Quaternary. He has abandoned the generally accepted five periods, and rejects Lyell's nomenclature altogether. British geologists will probably not follow this course unless the reasons for the change are quite convincing.
