The Development of Geochemistry

As other branches of chemical and physical science developed on the basis of principles and fundamental laws it was not satisfactory to let geochemistry remain simply as a collector of test results. Even geochemical science started to use physicochemical ways of looking at things.

The development of geochemistry in America illustrates these points. Its history bears some similarity to the histories of other hybrid specialties that emerged around the turn of the century, but in several important ways it constitutes an exception to the normal pattern of development. It did not take shape in the university. Rather it found its first expression in the United States in the laboratories of the U.S. Geological Survey and the Carnegie Institution of Washington. Only very gradually did it find a place in the university curriculum. Nor did it grow in response to... 

A quick look at the reference list of this textbook (initially conceived for Itahan university students) is sufficient to appreciate the leading role played by North American scientists in the development of geochemistry, and it is a great honor for me to present my appraisal of this fascinating discipline to readers whose mother tongue is English. 

Who was Victor Goldschmidt and what role did he play in the development of geochemistry and cosmochemistry ... 

His other studies, collected in 25 books, are very interesting as well. He organized knowledge on isomorphism, a study which supported the development of geochemistry. 

It is known that the reliability of analytical information obtained depends particularly on the range of reference materials (RM) used. The most of RMs developed by the Institute of Geochemistry, SB RAS are included in the State Register of certified types of National Certified Reference Materials of Russian Federation. The reference materials are routinely analyzed for the stability and their life durations are timely prolonged. Developed RMs (27 samples) characterize mainly mineral substances. 

Obtaining of data concerning the chemical composition of water is critical significance for monitoring water reservoirs and forecasting the quality of drinking water from different water supply sources. A dry residue is commonly used with the methods AAS, ICP-AES, ICP-MS (analysis of liquid) widely applied for determination of water composition. So it is vital to create a standard sample of the composition of dry residue of ultra-fresh Lake Baikal water, its development launched since 1992 at the Institute of Geochemistry SB RAS. 

One of the early applications of ITTFA was developed by Hopke et al. in the area of geochemistry [ 12]. By measuring the elemental composition in the crossing section of two lava beds, Hopke was able to derive the elemental composition of the two lava bed sources. This application is very similar to the air dust case given in the introduction of this chapter (see Section 34.1). 

Developed from a symposium sponsored by the Division of Petroleum Chemistry, Inc., and the Division of Geochemistry of the American Chemical Society at the Third Chemical Congress of North America (195th National Meeting of the American Chemical Society), Toronto, Ontario, Canada,... 

Shortly after the development of the early mass spectrometers, Li isotopes were identified by Francis Aston (1932). Although mass spectrometric techniques are those most commonly applied to the measurement of isotope ratios in geochemistry, attempts to quantify Li isotopes have been made using non-mass based emission methods (e.g., atomic absorption Zaidel and Korennoi 1961 various nuclear methods Kaplan and Wilzbach 1954 Brown et al. 1978 ... 

We strongly recommend that these conventions be adopted at this early stage in the development of Mg isotope geochemistry and cosmochemistry to eliminate the current ambiguity in the meaning of the A symbol in the literature. Presumably, confusion will be kept to a minimum if the same meaning is assigned to the same symbols in different isotope systems where ever possible. 

The importance of aqueous solutions in geochemistry can be appreciated if we recall that two-thirds of the surface of our planet is covered by water and that aqueous fluids of various salinities are determinant in the development of volcanic and metamorphic processes in the earth s upper mantle and crust. 

In conjunction with monitoring herbicide and degradation product occurrence, USGS research during the past decade has emphasized the development of methods for the analysis of triazine herbicides and their degradation products. To research and develop analytical methods for pesticides, a laboratory for organic geochemistry was established by... 

Developed from a symposium sponsored by the Division of Geochemistry at the 197th National Meeting of the American Chemical Society, Dallas, Texas,... 

At this stage in the development of the subject of the geochemistry of sedimentary carbonates, we have dealt primarily with the mineralogy and basic physical chemistry of the carbon system and some of its important phases. In the following chapters, this information and additional data and interpretations are utilized to explain the behavior of sedimentary carbonates in shallow water and deep marine environments, and during early and late diagenesis. The...
