In the preface for the First Edition of Glacial Geology we wrote that this book is the product of two things; an enthusiasm for glacial geology and a perceived need for a student text with which to stimulate this enthusiasm in others. Thirteen years on we still believe this to be the case. The First Edition has sold well and has been well-received by undergraduates studying the subject. In the First Edition of Glacial Geology we also wrote that the aim of the book is simple: to provide an account of glacial geology which is accessible to undergraduates and uncluttered from unnecessary detail. Although we have taken the opportunity to update and revise a lot of the content in this Second Edition, reflecting new developments in the subject, we have tried to stay true to this original aim. We hope you will still find this an accessible and helpful treatment of the subject and that by reading this book you will share some of our enthusiasm for glacial geology. <...>

Книга создана с целью определения картографических памятников на которых с древнейших времен изображалось Черное и Азовское моря. Это пятая часть из книг, охватывающих период испокон веков до 1800 г. В книге приведены карты созданные мировой цивилизацией в период 1750-1800 гг.

Compared with other mineral commodities, especially metals, whose utility has become evident by centuries of trial and error, the appreciation of uranium has developed from theories based in physics in the 1930s to exploit the unique energy density of uranium’s transformation in nuclear fission. Initially this was in the crucible of a world war, but always beyond military uses was the promise of the “uranium boiler” canvassed in the second British MAUD (Military Application of Uranium Detonation) report in July 1941—the work of “one of the most effective scientific committees that ever existed.” <...>

This book has been compiled and written by members of the Commission on Geomorphological Survey and Mapping of the International Geographical Union. Originally proposed in 1976 as a text to accompany and explain the lnternationtll Geomorphological Map of Europe (1: 2.5 million), the oudine of the book was prepared by the Commission at a meeting in Nove Mesto, Czechoslovakia, in 1977. Since then, there has been a considerable delay in publishing the International Map; meanwhile, work on this book progressed and has overtaken the schedule for printing the Map. At the same time, the book has been enlarged and its aims have changed to some extent: it is no longer envisaged simply as an explanation of the Map but as a work in its own right, providing the first comprehensive survey of the geomorphology of Europe <...>

The Cenozoic volcanism in the Tyrrhenian Sea region shows a very wide range of petrological, geochemical and isotopic compositions, which cover almost entirely the field of igneous rock occurring worldwide. Volcanic activity took place contemporaneously with the opening of the Ligurian-Provenзal and Tyrrhenian Sea basins, and with the formation of the Apennine-Maghrebian chain.

The basic purpose of this book is to present an analysis of the various geochemical methods applicable in the search for all types of thorium and uranium deposits. It is hoped that the data and comments presented will stimulate greater use and research in the methods, especially in those that have up to the present received relatively little attention <...>

Рений, германий, кобальт, никель, вольфрам — что между ними общего, почему столь разные металлы оказались под одной обложкой? В пяти новеллах авторы приводят обширный историко-фактографический материал по каждому из металлов, от первого письменного упоминания вплоть до использования в современной промышленности. Каждый рассказ это полноценный адаптированный для неспециалиста минерально-сырьевой обзор с расширенной исторической частью.

Для геологов, студентов геологических специальностей, любителей природы и всех, интересующихся историей геологических наук.

This book contains three major physical phenomena for active source seismology: underwater explosions, underground nuclear explosions and large-scale on-surface chemical explosions.
In particular we attempted to demonstrate how to use the technologies and applications in active source seismology and seismo-acoustics rather than the theoretical approach for the resolution as forensic explosion seismology in the light of an application for Defense Sciences.
