The implied background of the student seems unusual.
Also, there are instances where very specific or controversial details from the literature are given without indicating that they may not be widely accepted or even citing the appropriate reference e. Some problems in organization exist. For example, classification of rocks and rock series is split between Chapters 4 and 8.
Individual chapters may be oddly organized, as well, with Ch. This is one of the most important chapters in the book, and yet the various topics are presented in somewhat random sequence. Fractional crystallization is discussed last, after hybridization, assimilation, and autometasomatism deuteric alteration. It would seem more natural, in the chapter following the discussion of phase diagrams, to begin with fractional crystallization and discuss the various other processes afterward.
In keeping with the emphasis on field relations, the book includes chapters on "Volcanic Activity," "Forms and Structures of Intrusive Rocks" and "Petrography of Igneous Rocks".
These chapters are well-organized, but t h e y contain no figures whatever.
The intent presumably was to hold down the cost of the book. However, the professor who expects to use these chapters will find he needs a large collection of photographs and drawings of his own to supplement the text.
Timothy Grove Online NA Pages English This lecture note surveys the distribution, chemical composition, and mineral associations in rocks of the earth's crust and upper mantle, and establishes its relation to tectonic environment. The emphasis is on the use of chemistry and physics to interpret rock forming processes. Igneous and Metamorphic Petrology Aley K.

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.
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.
