Special Techniques
10.1 T his book is mostly concerned with the study of microstructures in normal
Introduction thin sections under the petrographic microscope. This is a fast, cheap method
which gives a lot of information on rock deformation, but other techniques are
10.2 also available for the study of small scale structures. In this chapter we give a
Techniques to Study short outline of all these techniques, some of which are relatively new. The aim is
Deformation Fabrics not to give a full introduction to each technique, or to allow the reader to use
these techniques independently. Rather, we wish to introduce alternative tech-
10.3 niques up to a level where the reader will be able to decide if a particular tech-
Methods to Measure nique is useful and applicable to his specific type of samples and scientific prob-
Lattice-Preferred lem. A choice of literature is provided for further reading on each subject. Infor-
Orientation mation is also given on methods of sample preparation. Since this book deals
with microstructures, we restrict ourselves to analytical laboratory techniques
10.4 that use minerals in their original arrangement in the rock, similar to that in a
Chemical and thin section, excluding techniques that use powdered or dissolved rocks or min-
