Epilogue – The rhymes, musings and riddles of the International Community of Geological Surveys (ICOGS)
Abstract Building on the present volume, which provides a snapshot of Geological Survey organizations (GSOs) from around the world in 2020, this epilogue provides a retrospective on past efforts to form an international consortium of GSOs. These efforts have had the noble aim of bringing GSOs together to address problems of global scale, but have not fully succeeded in building a sustainable organization. The paper summarizes international discussions held over the past three decades, provides some analysis and makes some suggestions on how a world association of GSOs may become useful, credible and workable.

ORIGIN OF THE AMERICAN QANTITATIVE IGNEOUS ROCK CLASSIFICATION: PART 2
Abstract Since Karl Pearson wrote his paper on spurious correlation in 1897, a lot has been said about the statistical analysis of compositional data, mainly by geologists such as Felix Chayes. The solution appeared in the 1980s, when John Aitchison proposed to use Iogratios. Since then, the approach has seen a great expansion, mainly building on the idea of the ‘natural geometry’ of the sample space. Statistics is expected to give sense to our perception of the natural scale of the data, and this is made possible for compositional data using Iogratios. This publication will be a milestone in this process. This book will be of interest to geologists using statistical methods. It includes the intuitive justification of the methodology, convincing through case studies and presenting user-friendly software, which includes a section for those who need to see the proof of the mathematical consistency of the methods used.
Abstract This volume is a collection of papers on the history of twentieth century geology, of which eight were presented at a Symposium organized by the International Commission on the History of Geological Sciences (INHIGEO) for the International Geological Congress at Rio de Janeiro in 2000. The book offers a conspectus of selected developments of twentieth century geology. It has grown from largely a field discipline, chiefly concerned with rocks at the Earth's surface, to one that extends to the planet's interior, and to space beyond. New ideas, instruments, and techniques have extended the scope of earth science to the macro and the micro. Theories abound. One paper raises some of the social and political problems faced by modern geology. The volume is intended as a prolegomenon to some future synthetic understanding of twentieth century earth sciences. It should appeal to a wide range of geoscientists and historians of science.
