This book is an illustrative introduction to metamorphic rocks as seen in the field, designed for advanced high school to graduate-level earth science and geology students to jump-start their observational skills. In addition to photographs of rocks in the field, there are numerous line diagrams and examples of metamorphic features shown in thin section. The thin section photos are all at a scale and in a context that can be related to views seen in the field through a hand lens.
providing photographs of metamorphic rocks in the field.photomicrographs at a scale that translates to a hand lens views.line drawings outlining key theoretical concepts.includes metamorphic rocks related to faulting, metasomatic processes, and partial melting.with descriptions of illustrations that include what one can see and how to look for it.content is accessible for students from high school to graduate school.this book has been taken over from Manson publishing, and is part of their successful series of practical books for study and reference, produced to the highest standards in full colour and at affordable prices.
