Theory of Continental Drift: a Symposium on the Origin and Movement of Land Masses, both Inter-Continental and Intra-Continental, as proposed by Alfred Wegener

Abstract

THE complex problem of continental drift has everywhere been the subject of animated discussion in geological circles during recent years, and the publication of the papers presented at a symposium held in New York late in 1926 serves a valuable purpose in bringing together the considered opinions of some of the leading geologists of America and Europe. The American Association of Petroleum Geologists is to be congratulated not only on having staged a spirited and fruitful discussion, but also on its enterprise in making the contributions available in printed form to a worldwide audience. The book opens with a broad-minded and constructive review of the problem by Dr. van der Gracht; this is followed by papers from thirteen other authors, for the most part severely critical; and finally, Dr. van der Gracht summarises the various arguments brought forward, and restores the balance by showing that many of the objections raised need not stand unanswered.
