This hand pocket-sized field guide describes how metamorphic rocks and rock masses may be observed, recorded and mapped in the field. Written at a level suitable for earth science undergraduate students, The Field Description of Metamorphic Rocks is an essential tool for any geologist – student, professional or amateur – faced with the task of making a general description of an area of metamorphic rocks. A clear, systematic framework, together with numerous colour diagrams, illustrations and checklists, enables readers to produce useful and broadly similar descriptions, despite possible differences of background or specialist interest. Additional information is also provided to aid those who are undertaking a field mapping and report course.
