Founded in 1807, the Geological Society of London has beenpublishing since 1845 and now distributes its journal to Fellowsthroughout the world. This Handbook is published as part ofa series of authoritative practical guides to field geology.

The Field Description of Metamorphic Rocks
"This handbook describes how metamorphic rocks and rock masses maybe observed, recorded and mapped in the field. Written at a levelsuitable for undergraduate students of geology, this book (as withits companion volumes in the series) has firmly established itselfas an essential tool for any geologist -- student, professional oramateur -- faced with the task of making a general description ofan area of metamorphic rocks. A clear, systematic frameworktogether with numerous diagrams, illustrations and checklistsenables 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 willalso interest many geologists who do not regularly work inmetamorphic terrains and will be particularly useful to engineeringgeologists and civil engineers who are often concerned withdescribing the fabrics of metamorphic rocks without being concernedabout their origins."
