It is to the use of the comparative method that we owe the striking generalisations of Neuinayr and the philosophical views of Suess. Even in the study of a particular district, comparison with other areas is invaluable ;for the key to the geology will often be found in some far distant region. South Devonshire, for example, was very imperfectly understood until Mr. Ussher applied the knowledge which had been won in the Rhenish Mountains. There is, however, no text book in theE nglish language which jaffords sufficient help in such comparisons, for there is none which gives an adequate account even of the geology of Europe ;and it is with the object of supplying this deficiency, in part at least, that the translation of Dr. Kayser sL ehrbuch der geologischen Formationskunde has been undertaken. Dr. Kayser swork was intended primarily for use in Germany; but the space devoted to other countries is much larger than in earlier text books. In the present edition very considerable additions have been made to the portions descriptive of extra-G erman countries. These additions are most numerous in the first half of the work, while in the latter half the greatness of the subject and the limits of space have made themselves more severely felt. Extra-E uropean rocks have necessarily received but brief notice.

Forgotten Books' Classic Reprint Series utilizes the latest technology to regenerate facsimiles of historically important writings. Careful attention has been made to accurately preserve the original format of each page whilst digitally enhancing the aged text.
This book was originally published prior to 1923, and represents a reproduction of an important historical work, maintaining the same format as the original work. While some publishers have opted to apply OCR (optical character recognition) technology to the process, we believe this leads to sub-optimal results (frequent typographical errors, strange characters and confusing formatting) and does not adequately preserve the historical character of the original artifact. We believe this work is culturally important in its original archival form. While we strive to adequately clean and digitally enhance the original work, there are occasionally instances where imperfections such as blurred or missing pages, poor pictures or errant marks may have been introduced due to either the quality of the original work or the scanning process itself. Despite these occasional imperfections, we have brought it back into print as part of our ongoing global book preservation commitment, providing customers with access to the best possible historical reprints. We appreciate your understanding of these occasional imperfections, and sincerely hope you enjoy seeing the book in a format as close as possible to that intended by the original publisher.

Paperback. Etat : New. Print on Demand. This book provides a comprehensive study of the Earth's most ancient rock formations, known as the Archaean rocks. It highlights the unique characteristics of these rocks, including their crystalline structure, absence of fossils, and globally-consistent composition. The author explores the various theories on the origin of the Archaean rocks, ranging from their formation as the Earth's original crust to their transformation from pre-existing sediments or eruptive rocks through intense geological processes. The book examines the distribution and occurrence of Archaean rocks worldwide, analyzes their composition and structure, and discusses their significance in understanding the early history of the Earth. The author concludes that the study of Archaean rocks offers valuable insights into the processes that shaped our planet during its formative stages and provides a foundation for understanding subsequent geological events. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
