Opis

Geological Society of London Handbook Series Edited by Keith Cox Founded in 1807, the Geological Society of London has been publishing since 1845 and now distributes its journal to Fellows throughout the world. This Handbook is published as part of a series of authoritative practical guides to field geology. The Field Description of Metamorphic Rocks
"This handbook describes how metamorphic rocks and rock masses may be observed, recorded and mapped in the field. Written at a level suitable for undergraduate students of geology, this book (as with its companion volumes in the series) has firmly established itself as 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 diagrams, illustrations and checklists enables readers to produce useful and broadly similar descriptions, despite possible differences of background or specialist interest. This well-written and well-produced little text will, I am certain, become standard reading for most geology undergraduates. It will also interest many geologists who do not regularly work in metamorphic terrains and will be particularly useful to engineering geologists and civil engineers who are often concerned with describing the fabrics of metamorphic rocks without being concerned about their origins."
