At last geochemists are offered one comprehensive reference book which gives the Eh-pH diagrams for 75 elements found in the earth's surface environment, including transuranic and other radioactive species.
Discusses the global evolution of the earth, such as core-mantle separation, mantle-crust evolution, origin of ocean-atmosphere system, on the basis of isotope earth science andpaleomagnetism, where recent devlopment in planetology andastrophysical theories are extensively taken into account.
On May 25,1978, the Commission on Toxicology ofthe Division of Clinical Chemistry of the International Union of Pure and Applied Chemistry (IUPAC) established its Subcommittee on Environmental and Occupational Toxicology of Cadmium following aseries of Commission meetings in Kristiansand, Norway.
A distinction between contamination and pollution is useful when we wish to consider what strategies to adopt in researching the impact of anthropogenic activities on the marine environment.
In Nordic literature a remarkable discussion of the northern light appears in Kongespeilet (The King's Mirror) a thirteenth-century Norwegian chronicle.
It is now well known that the mid-ocean flow is almost everywhere domi- nated by so-called synoptic or meso-scale eddies, rotating about nearly vertical axes and extending throughout the water column.
I am pleased to be able to introduce this book by Monsieur lean-Claude Gall, firstly because it is a book, secondly because its author has been a colleague for 15 years, and finally because it is a book which demonstrates the growing importance of Palaeobiology.
Coated grains have always attracted attention, at first of naturalists, and later of geologists, and the interest in these peculiar bodies was re- lated both to their intriguing form and their significance in facies inter- pretation and sedimentology and to their relevance to accumulations of hydrocarbons and other mineral deposits.
Progress in Precambrian geology has been exceptionally great, indeed quite striking for geologists of the older generation; only some 30-40 years ago the Precambrian appeared as an uncertain and even mystic prelude to geologic evolution.
When, in 1966, the Gennan Research Society directed the attention of oceanographers in the Federal Republic of Ger- many to problems of marine pollution, I was not enthusiastic.
The enormous public interest of specialists as well as of engaged and concerned citizens in the energy problem can be understood in view of the fact that the future of national and world-wide economy depends on the availability of sufficient primary energy.
Students of a phenomenon as common but complex as andesite genesis often are overwhelmed by, or overlook, the volume and diversity of relevant information.
In these days of information explosion and high-cost publishing, it is perhaps only reasonable for an author to convince the reading public that it is getting something worth reading.
Our colleagues from the French-speaking parts of Switzerland - the Suisses romands - and above all the committee of the 3rd Cycle, e Earth Sciences (3 Cycle, Sciences de la Terre) honored us by asking us to give a course on Isotope Geology for the year 1977.
Colloid science has been applied by soil chemists and clay mineral- ogists for many years, and some of the most important studies on the behavior of colloids have been contributed by them.
The problem of time-and strata-bound formation of ore deposits has during the past decade become one of the most debated topics in cur- rent international discussion.
