Riassunto

This study of igneous petrology shows how data derived from petrographic, geochemical and field studies can be used in the formulation and testing of petrogenetic hypotheses. It also deals with methodology as an important aspect of igneous petrology. Exercises are added to most chapters, and answers are given separately: the treatment is carefully graded in terms of difficulty and degrees of specialization.
