The founders of geology at the beginning of the last century were suspicious oflaboratories. Hutton's well-known dictum illustrates the point: "There are also superficial reasoning men . . . they judge of the great oper ations of the mineral kingdom from having kindled a fire, and looked into the bottom of a little crucible. " The idea was not unreasonable; the earth is so large and its changes are so slow and so complicated that labo ratory tests and experiments were of little help. The earth had to be studied in its own terms and geology grew up as a separate science and not as a branch of physics or chemistry. Its practitioners were, for the most part, experts in structure, stratigraphy, or paleontology, not in silicate chemistry or mechanics. The chemists broke into this closed circle before the physicists did. The problems of the classification of rocks, particularly igneous rocks, and of the nature and genesis of ores are obviously chemical and, by the mid- 19th century, chemistry was in a state where rocks could be effectively analyzed, and a classification built up depending partly on chemistry and partly on the optical study of thin specimens. Gradually the chemical study of rocks became one of the central themes of earth science.

Elemental Analysis in Geochemistry: A. Major Elements provides an introduction to basic classical and modern instrumental ""macro"" methods for geochemical research. The intention is to acquaint the beginning analyst or geochemist with the minimum of analytical methods required to satisfactorily perform a complex silicate or similar analysis. By combining classical and modern instrumental methods in one book, strong emphasis is put on the importance of the analyst's ability to grasp the general structure and relation of some of the most frequently used analytical techniques. The book begins with basic concepts such as the preparation and decomposition of samples; statistical evaluation; and methods of separation and analysis. It outlines the classical qualitative separation scheme, which is very useful in understanding the analytical problems of complex mixtures, especially when hydrogen sulfide group metals are present. It discusses analytical techniques such as the detection and quantitative gravimetric analysis of silicon; volumetric or titrimetric methods; emission photometric analysis; atomic absorption spectroscopy; nondestructive instrumental methods; methods in X-ray spectrochemistry; and developments in neutron activation analysis.

Chemical principles are fundamental to the Earth sciences, and geoscience students increasingly require a firm grasp of basic chemistry to succeed in their studies. The enlarged third edition of this highly regarded textbook introduces the student to such ‘geo-relevant’ chemistry, presented in the same lucid and accessible style as earlier editions, but the new edition has been strengthened in its coverage of environmental geoscience and incorporates a new chapter introducing isotope geochemistry. The book comprises three broad sections. The first (Chapters 1–4) deals with the basic physical chemistry of geological processes. The second (Chapters 5–8) introduces the wave-mechanical view of the atom and explains the various types of chemical bonding that give Earth materials their diverse and distinctive properties. The final chapters (9–11) survey the geologically relevant elements and isotopes, and explain their formation and their abundances in the cosmos and the Earth. The book concludes with an extensive glossary of terms; appendices cover basic maths, explain basic solution chemistry, and list the chemical elements and the symbols, units and constants used in the book.

Updated throughout with the latest data and findings, the Second Edition of Essentials of Geochemistry provides students with a solid understanding of the fundamentals of and approaches to modern geochemical analysis. The text uses a concepts of chemical equilibrium approach, which considers the reactions that occur as a result of changes in heat production and pressure within the Earth to introduce students to the basic geochemical principles. This text is for those who want a quantitative treatment that integrates the principles of thermodynamics, solution chemistry, and kinetics into the study of earth processes. This timely text contains numerous examples and problems sets which use SUPCRT92 to allow students to test their understanding of thermodynamic theory and maximize their comprehension of this prominent field. New sections introduce current “hot” topics such as global geochemical change with the short and long term carbon cycle, carbon isotopes and the Permo-Triassic extinction event, kinetics and the origin of life and the use of boron and nitrogen isotopes.

Radioanalysis in Geochemistry

Radioanalysis is indispensable to the present-day geologist and geochemist, due to its three main applications: activation analysis; radiotracer experiments; and the measurement of natural'' radioactivity. The aim of this monograph is to summarize that part of the use of radioanalysis which emerges from a confrontation with other analytical methods. After an introductory chapter on the scope of radioanalysis and the aim of the book, Chapter 2 deals with sampling procedures for rocks/minerals, sediments and water. In activation analysis the emphasis is on neutron activation and related prompt methods, with either the nuclear reactor or the neutron generator. The use of the cyclotron and the linear accelerator come into view only when they offer unique or superior results. Distinction is made between the purely instrumental procedures (Chapter 3) and those which imply pre- or post-irradiation separations. Elements are discussed according to the groups of the periodic table. Radiotracer experiments are described, based on mass- and activity-balances. Only those radiotracers which are commonly available are considered.
