Full Text quantitative rapid analysis for industrial product control. A major concern in energy-dispersive X-ray analysis is the practical inconvenience of cryogentic temperatures required for the c o m m o n l y used Si Li detector. Most of the first seven chapters reports on promising developments in alternative detector materials in particular the promising HgI2. Its energy resolution remains somewhat worse than the Si Li , but already finds quantitative application in the analysis of simple metal alloys, for example. Particularly promising results using polarized X-rays are reported, with detection limits and accuracy comparable to t h a t in wave-length dispersive systems. Desk-top minicomputers for on-line analytical control and data reduction are in frequent use. Several hardware and software designs are reported using cheap K minicomputers.
The magma generation leads to basalt-peridotite--ecologite and also to granitic systems. The diversification o f ascending magmas comprises differentiation, assimilation or contamination, magma mixing, magma b u o y a n c y , and also the mechanism of ascent. Changes in fabric and composition of rock bodies, without the intervention of a silicate melt are induced by various modalities: thermal, metasomatic, contact, regional, sub-sea-floor, burial, shear, shock or impact of meteorites. They result in crystalloblastic series crystallization strength of A.
Harker, , from most to least euhedral; metamorphic differentiation grade, zones, facies, polymetamorphism , all leading to characteristic compositions as fabrics and lineations.
Field relations are revealed by mylonite zones; contact aureoles; burial, regional and sub-sea-floor metamorphic bodies; high-pressure blueschists.
Serpentinite belts indicative of ancient subduction zones. A very rich chapter on the Origin o f fabric: 1 nucleation and crystal growth; 2 dislocations: edge dislocations; but also dislocations can be mobilized and even eliminated recovery ; 3 the distinction between stress and strain elastic or plastic ; ductile flow twin gliding , kinkband, point d e f e c t s bending, hydrolytic weakening, pressure solution, segregation layering. Metasomatism is studied in view of differentiation, zoning, rate theory and steps.
Proterozoic rocks. There are basaltic intrusions, anorthosites and rapakivis. Mobile belts as the Grenville Province are a part of the continental revolution. Mantle evolution Sr and Nd isotopes is dealt with and also core segregation.
An interesting chapter is devoted to Extraterrestrial petrology: the Moon, Mercury, Venus, Mars and the meteorites. Almost each chapter is followed by a summary, s tu d y questions and references.
Developments in Petrology, 9. This b o o k , in the author's words, a t t e m p t s to "present a more or less systematic review of metamorphic processes and metamorphosed rocks. The result makes for difficult reading, and in places incomprehension. The b o o k is organized into four main chapters, the first three dealing with m e t h o d s of study, physical conditions, and chemical character of metamorphism.
The f o u r t h chapter, which comprises m or e than a third of the book, is a discussion of the various kinds o f m e t a m o r p h i c rocks that f or m from sedim e n t a r y and igneous rocks under different m e t a m o r p h i c conditions.

Almost nothing is said of the origin and early history of the solar system, for which the study of meteorites is of key importance. On the other hand, the book contains a wealth of information on historical and phenomenological aspects.
The author is to be congratulated for assembling impressive and interesting illustrations.
In addition, the publisher should be commended for providing a well-produced book with nice binding, layout, and graphics at a reasonable price considering the format of the book and the number of illustrations. Apart from the uneven treatment of the subject, however, there are some flaws ranging from scientific misconceptions to inconsistencies and typos.
I assume that more scientific scrutiny and better proofreading would have helped to catch some of these mistakes. Among the scientific misconceptions are I meteorites of t mass do not vaporize completely upon impact p. Despite these inaccuracies, the bulk of the text is correct and readable.
In this respect, chapter 8 is especially deplorable. There should be just one sentence: If we are to attract quality students to petrology in the future, the black-magic approach to teaching must be discarded in favor of a fully quantitative approach.
The first chapter sets tbe tone, and includes a discussion of pressure distribution within the earth, temperature gradients and heat flow in the lithosphere, heat sources within the earth, and the steady-state geotherm. However, a list of chapter titles does not do justice to the contents. The chapter on intrusion of magma, for example, includes an introduction to fluid dynamics whereas that on the cooling of igneous bodies includes a very good summary ofthe theory of heat conduction error functions included!
The next four chapters deal with thermodynamics and phase equilibrium. Chapters 11 and 12 discuss the effects of volatiles on melt equilibria including an introduction to two-oxide thermobarometry and crystal growth, whereas magmatic processes and igneous rock associations arc covered in chapters I3 and I found the section on metamorphism to be patticularly good.
Philpotts covers all of the important topics and concepts in pages, yet coverage of some of these e. Also, metamorphism is largely governed by exactly the same principles described in earlier chapters in the book.
The final two chapters are on isotope geochemistry dating methods, evolution of isotopic reservoirs and stable isotopes and on the origin of rocks advective heat transfer, conditions for melting, melt generation and accumulation, mantle composition and partial melting. I do have some minor criticisms of the book. I think that more Philpotts. Prentice-Hall, X.
The problem with most texts, in my view, is that they emphasize petrogenesis. This approach usually involves presentation of a bewildering number of facts and descriptions of numerous localities followed by an attempt at synthesis to reach qualitative conclusions. All too often, the reader is left with the impression that nearly all of the major questions in petrology have been satisfactorily answered.
Nothing could be further from the truth. Petrology is a rapidly evolving subject, and petrogenetic models are discarded or modified as data accumulate and are interpreted. Consequently, books which emphasize petrogenesis are soon out of date and their main use is that they give an overview of the ideas prevailing just prior to the time of publication. As recognized long ago by Bowen, it is the basic principles that should be emphasized because these provide the coherent framework within which petrogenetic models must be constructed.
This is exactly the philosophy followed by Anthony R. Philpotts in Principles Igneous and Metamorphic Petrology. This book is a most welcome, long-awaited, and important addition to the geological literature. Philpotts treats petrology largely in terms of simple models that can be tested by quantitative analysis.
