Geology In The Field

Replaces Compton's Manual of Field Geology (1962). A guide to advances in the increasingly broad and interpretive discipline of formation mapping theory. Thorough, yet compact enough for use in the field, it consists of brief descriptions of textures and structures useful in interpreting depositional environments, kinds of volcanic activity, and plutonic events and conditions. Included are procedures often reserved for the laboratory or office: staining rocks, correcting orientations of current indicators, constructing profile sections of folds, measuring strains, making photogeologic interpretations, and more. Covers pre-field considerations, methods of observation and measurement, recognition of key geologic features, and preparation of a report. Illustrated with composite drawings. Fourteen appendixes provide systemized data and procedures.

This book is a field guide that describes and explains the commonest minerals and rocks as well as introducing the most important fossil groups. In addition, a variety of geological structures are described and illustrated in the numerous diagrams and photographs. The guide is your perfect companion for hikes or walks in the countryside, inviting you to discover the geology hidden behind the landscapes surrounding us, as well as helping you to recognise the various minerals, rocks and fossils, you might encounter. Geology is a science that only really comes to life when we are outside, for example, on walks or hikes along the coast or through national parks. With a little knowledge you will be able to experience the landscape in a completely different way. The rocks will “come alive”, so to speak, and you will be able to read their history like a book - understanding the range and complexity of geological processes which have formed the Earth beneath our feet. Such processes - an interplay of magmatism, tectonics, metamorphosis and sedimentation, as well as climate and sea-level change - have shaped the Earth over millennia and continue to do so even at the present time. The book is aimed at nature lovers of all types, as well as students of geology – in fact, anyone who is interested in the world around us. It will provide the perfect companion for walks or hikes in the countryside. This book is a translation of the original German 1st edition Pocket Guide Geologie im Gelände by Tom McCann, published by Springer-Verlag GmbH Germany, part of Springer Nature in 2019. The initial translation was done with the help of artificial intelligence (machine translation by the service DeepL.com). A subsequent detailed revision by the author ensures that the book reads stylistically like a conventional translation. Springer Nature works continuously to further the development of tools for the production of books and on the related technologies to support the authors.

This book helps a novice to explore the terrain independently. Geoscience fieldwork with a focus on structural geology and tectonics has become more important in the last few years from both academic and industrial perspectives. This book also works as a resource material for batches of students or geological survey professional undergoing training as parts of their course curriculum. Industry persons, on the other hand, can get a first-hand idea about what to expect in the field, in case no academic person is available with the team. This book focused on structural geology and tectonics compiles for the very first time terrains from several regions of the globe.

This book features information not found in other field geology texts, including identification and modern classification of rocks, means of recognizing and interpreting primary structures in rocks (which reveal their origin), coverage of engineering geologic maps, and recognition of recently active faults. The book follows the typical sequence of a student's experience in learning field work - starting with the first observation of an outcrop and proceeding to methods of measurement and mapping, ending with a preparation of a full geologic report.

Although there are numerous publications on the geology of high-grade gneiss terrains, few descriptions exist of how to map and carry out structural analysis in these terrains. Textbooks on structural geology concentrate on technIques appli cable to low-grade terrains. Geologists who have no experience of mapping high-grade gneisses are often at a loss as to how to apply techniques to high grade rocks that were developed for low to medium grade metamorphic terrains. Any study of deep crustal processes and their development through time should begin with examination of the primary data source - outcrops of high grade metamorphic terrains. We feel that the urge to apply advanced techniques of fabric analysis, petrology, geochemistry, isotope geochemistry and age deter mination to these rocks often results in brief sampling trips in which there is little, if any analysis of the structural and metamorphic history revealed by outcrop patterns. Many studies of the metamorphic petrology and geochemistry of high-grade gneiss terrains make ineffective use of available field data, often because the authors are unaware of structural complexities and of the ways to recognise and use them. This is unfortunate, because much data can be collected in the field at minimal cost that cannot easily, if at all, be obtained from material in the laboratory. The primary igneous or sedimentary nature of a rock, the relative age of intrusive veins, and the sequence of deformation that they under went, can usually best be determined by straightforward observation in the field.

An excellent field reference to aid in recognizing, interpreting and describing geologic features at the outcrop. Detailed descriptions, illustrations and photographs of geologic features in their field setting.

Presents an illustrated field guide to geology that explains the evolution of the Earth.
