Geology and Tectonics through Earth's history and selected gold deposits of Hebei Province, NE china, are briefly described in this monograph. Additionally, instructive maps, diagrams and photographs as well as aspects of metallogenesis and a proposed metallogenetic model make it valuable for scientists and practitioners working in the field of geology of Precambrian rocks associated with gold deposits.

The journey to the centre of the earth is a voyage like no other we can imagine.Over 3,000 km below the earth's surface an extraordinary inner world the size of Mars awaits us.Dive through the molten iron of the outer core and eventually you will reach a solid sphere - an iron-clad world held within a metal sea and unattached to anything above.At the earth's core is the history of our planet written in tempe...

This concise, accessible, market-leading textbook brings together the wide-ranging fundamentals students need to understand rocks and minerals, and shows them how they relate to the broader Earth, materials and environmental sciences. Designed specifically for one-semester courses, it is beautifully illustrated to explain the key concepts in mineralogy and petrology. This edition has been fully updated based on classroom experience, and new features include a completely new chapter providi...

This book contains a wealth of information on all aspects of amber, it’s appearance, diagnostic properties, common treatments and imitations. Designed for the beginner or experienced, it will greatly assist those wishing to find out more about how to correctly identify amber. There is information on the physical and optical properties of amber. There is also details on the correct readings for amber, from various gemmological instruments, such as ultra-violet light, refractometer, to name ...

The analysis of polar ice cores has proven to be very instructive about past environmental conditions on the time scale of several climatic cycles, and recent drilling operations have provided information of great value for global change issues.The book presents the most recent data extracted from Greenland ice cores and surface experiments and compares them with former Antarctic results. It contains background articles, original contributions and group reports of interest to scient...

Key biogeochemical events in the ocean take place in less than a second, are studied in experiments lasting a few hours, and determine cycles that last over seasons or even years. Models of the controlling processes thus have to take into account these time scales. This book aims at achieving consensus among these controlling processes at all relevant time scales. It helps understand the global carbon cycle including the production and breakdown of solved organic matter and the production,...

This book is a collection of ISRM suggested methods for testing or measuring properties of rocks and rock masses both in the laboratory and in situ, as well as for monitoring the performance of rock engineering structures. The first collection (Yellow Book) has been published in 1981. In order to provide access to all the Suggested Methods in one volume, the ISRM Blue Book was published in 2007 (by the ISRM via the Turkish National Group) and contains the complete set of Suggested Methods ...

" ... as soon as one has traversed the greater part of the wild sea, one comes upon such a huge quantity of ice that nowhere in the whole world has the like been known." "This ice is of a wonderful nature. It lies at times quite still, as one would expect, with openings or large fjords in it; but sometimes its movement is so strong and rapid as to equal that of a ship running before the wind, and it drifts against the wind as often as with it." Kongespeilet - 1250 A.D. ("The Mirror of King...

Covering a key connection between geological processes and life on Earth, this multidisciplinary volume describes the effects of volcanism on the environment by combining present-day observations of volcanism and environmental changes with information from past eruptions preserved in the geologic record. The book discusses the origins, features and timing of volumetrically large volcanic eruptions; methods for assessing gas and tephra release in the modern day and the palaeo-record; and th...

This book contains a wealth of information on all aspects of the mineral feldspar, and its varieties. Designed for the beginner or experienced, it will greatly assist those wishing to find out more about how to correctly identify feldspar minerals. Each feldspar variety is shown, with information on the physical and optical properties. There is also details on the correct readings for feldspar and its many varieties, from various gemmological instruments, such as chelsea filter, spectrosco...

Preface Uranium is a radioactive element and a heavy metal which is naturally occurring in ground and surface water. Although uranium is enriched in granites and gneiss ground water from these host rocks often shows low to intermediate uranium con centrations, while some ground waters from sandstone and carbonate aquifers show elevated uranium concentrations up to several hundred mg/1 without man made impact. On the other side, surface water contains increased anthropogenic uranium concent...
