other persons helped in one way or the other, either by providing samples with inter-

discussing the meaning of microstructures. Their help is also gratefully acknowledged.

funding for our research, the results of which have been used in this book; this support
is gratefully acknowledged. R.A.J.T. thanks the Brasilian Research Council (CNPq)

About This Book
This book deals with the description and interpretation of small scale structures in
deformed rocks as seen in thin section through the optical microscope. The book is
meant for advanced undergraduate and graduate students, and is best used in combi-
nation with a practical course where thin sections can be studied and discussed. In our
experience, a collection of 100–200 thin sections with examples from structures treated
in our Chapters 3–9 are sufficient for such a course.
In Chapter 1 the ‘philosophy’ of how we think that microstructures can be under-
stood is discussed, including their usefulness in tectonic studies. Chapter 2 gives a
simplified, non-mathematical background in kinematics and rheology, meant to ex-
plain the terminology used in the interpretation of microstructures. Deformation on
the grain scale and deformation mechanisms are treated in Chapter 3. Chapters 4 to 7
form the core of the book and deal with the most commonly observed microstruc-
tures. In Chapter 8 some primary microstructures from igneous and sedimentary rocks
are discussed, and in Chapter 9 a brief outline is given of a new development in micro-
tectonics which we called microgauges: structures that can be used to obtain quantita-
tive data from deformed rocks. Chapter 10 describes a number of additional tech-
niques other than optical microscopy. These techniques either use thin sections, or
can be used in combination with optical microscopy to obtain additional data. The
descriptions are short but should allow the reader to decide if it is advantageous to use
an unfamiliar technique, available outside the home department. Chapter 11 gives an
overview of the current state of the art of experimental studies. Chapter 12 describes
problems involved with sampling and preparation of thin sections, including the prob-
lem of the interpretation of three dimensional structures using two-dimensional sec-
tions. A glossary and index are given at the end of the book; the definitions in this
glossary reflect our opinion on the meaning of the terminology as used at present. A
number of boxes explaining subjects in more detail are present in several chapters.
Figures in these boxes are numbered separately, starting with “B.” and the chapter
number.
