A pictorial guide to metamorphic rocks in the field / Практическое полевое руководство по метаморфическим горным породам
This book is a photographic introduction to metamorphic rocks. It is meant to be a survey of mostly typical metamorphic rocks, minerals, and structures as they appear in the field, and the metamorphic processes that make them. Its purpose is to help guide the eye of any student of geology to better see the geologic features in metamorphic rocks that might otherwise remain invisible or obscure. This book is a training tool, one of many, to help budding geologists of metamorphic rocks, young and old. <...>
