Nothing could be further from the truth. Petrology of Sedimentary Rocks. 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. Igneous rocks: Read more.
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. Accordingly, description of field aspects and of rock associations is kept to a minimum, and there is no lengthy discussion of petrogenesis on the basis of magma-type, metamorphic rock-type, or tectonic environment.
Roth physical and chemical aspects of petrology are clearly and lucidly explained, and the text is punctuated by numerous, helpful illustrations. Thankfully, Philpotts does not sidestep the need to quantify petrologic, geophysical, and geochemical phenomena.
Indeed, one of the strong points about the book is that the mathematics necessary to understand the basic concepts is not only included, but derivations of important relationships are given in full.
Problem sets given at the end of each chapter reinforce and extend the concepts described in the text and provide many ready-made examination questions for the instructor , and are an integral part of the material covered. Use of this text should convince all geology students of the need to formulate models in mathematical terms, and of the need to learn to Institute ofGeochemistry University of Vienna A Vienna, Austria Christian Koebert Book Reviews discussion of trace element systematics would have been useful.
After all, interpretation of trace element data is critical for constraining the role of processes such as assimilation and magma mixing, as well as for inferring the characteristics of the source regions of magmas. Similarly, I would like to have seen the chapter on isotope geochemistry placed earlier and greater use of isotopic data made in the section on assimilation.
However, these are minor points and reflect my own prejudices. This book is designed as an introductory text for students who have completed undergraduate coursework in physics, chemistry and calculus. It could be used both for undergraduate and beginning-level graduate courses, and would serve as a useful supplementary text for introductory courses in other subjects e. Percolation and rocks.

Concerning rock body formation, chemical composition and fabrics are considered carefully. Interpretative Petrochemistry investigates the magmatic differentiation either by liquid immiscibility, or volatile transfer, or separation of crystals and liquid , the gravitational segregation, and Stokes' law. The reader is initiated to various variation diagrams. Many special terms are d e f n e d: Among others siderophile, chalcophile and lithophile elements are noted, and among the last rare-earth elements REE , and also oxygen, rubidium, strontium, samarium and n e o d y m i u m isotopes.
Calc-alkaline volcanic rocks, from rhyolite to basalt and calc-alkaline plutonic rocks, from granite to gabbro, are carefully studied. For granites, the Tuttle--Bowen classification is outlined: Composition patterns. I igneous type: Here the bulk of oceanic and plateau basalts are set alkali-olivine, tholeiitic basalt Hawaiian-type flows ; also gabbroic, ultramafic and serpentinized ophiolites from oceanic rifts. Alkaline rocks.
There are basanites and phonolites, the alkaline suite shoshonite, nephelinite, ijolite , carbonatites, fenitization, and finally the kimberlites with diamond.
Constitution o f magmas. The magmas may be considered from several viewpoints: The crystallization of a magma of constant or variable composition results in nucleation and crystal growth, according to the Clapeyron equation, chemical potential, sequential precipitation, the Gibbs phase rule, the Lever rule, congruent and incongruent melting, notwithstanding the role of volatiles.
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: 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: 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:
