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.

GEOLOGICAL FIELD TECHNIQUES The understanding of Earth processes and environments over geological time is highly dependent upon both the experience that can only be gained through doing fieldwork, and the collection of reliable data and appropriate samples in the field. This textbook explains the main data gathering techniques used by geologists in the field and the reasons for these, with emphasis throughout on how to make effective field observations and record these in suitable formats. Equal weight is given to assembling field observations from igneous, metamorphic and sedimentary rock types. There are also substantial chapters on producing a field notebook, collecting structural information, recording fossil data and constructing geological maps. Geological Field Techniques is designed for students, amateur enthusiasts and professionals who have a background in geology and wish to collect field data on rocks and geological features. Teaching aspects of this textbook include: step-by-step guides to essential practical skills such as using a compass-clinometer, making a geological map and drawing a field sketch; tricks of the trade, checklists, flow charts and short worked examples; over 200 illustrations of a wide range of field notes, maps and geological features; appendices with the commonly used rock description and classification diagrams; a supporting website hosted by Wiley-Blackwell is available at www.wiley.com/go/coe/geology

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.

Describes the methods, procedures, and specialized equipment of field work in geology and includes a guide to making maps of specific areas.

A pocket-size text in a spiral notebook, Procedures in Field Geology was written to provide a presentation of essential field procedures without the bulk and cost of a comprehensive textbook. The field procedures in the text are those that emerged through years of teaching in the Wind River Mountains in Wyoming.

A modern quantitative approach to structural geology and tectonics for advanced students and researchers.

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.

This is the first field guide written for the general public and beginners in geology in New Zealand. Now fully revised and updated, it shows travellers in New Zealand something of the tremendous variety of our rocks, minerals and fossils and describes what to look for in many areas where rock formations are prominent. It covers the history of New Zealand from its beginnings on the sea floor some 600 million years ago to its present patchwork landscape of volcano, range and plain. This land was formed from many different layers of rock - volcanic flows, forest debris, ocean mud. All these have special characteristics, which are explained and illustrated to enable readers to find the layers and understand their origins and what they can tell us about the landscapes of the past. The crystals that grew in the rocks and the remains of living creatures that were preserved are also illustrated and described. Written in simplified terms, it includes an introductory chapter on general geology, A geological time chart and quick reference maps of the North Island and the South Island for travellers.

Geology is the scientific study of the Earth's surface, its evolution and the processes that have led to its change. The demonstration of the age of the Earth, chronicling of the Earth's geological history, evidence for plate tectonics, and the understanding of past climates have been possible because of advancements in the field of geology. Rock analysis is the most significant area of geological studies. Rock can be of three types, namely sedimentary, igneous and metamorphic. The techniques used in geological investigations are fieldwork, chemical analysis, numerical modeling, rock description and physical experimentation. Hydrocarbon and mineral exploration, hydrological studies, understanding of natural hazards and past climates, etc. are explored from within the framework of geology. This textbook is a valuable compilation of topics, ranging from the fundamental to the most complex theories and principles in the field of geology. It further elucidates the techniques and applications of geology in a multidisciplinary manner. The book strives to be a complete source of information for all students who are looking for an elaborate reference text on geology.
