At a time when 'textural' evidence is regarded as being 'obvious' ( . . . ) it becomes more and more difficult to find illustrations or even descriptions of the arrangements of the various constituents of 'traumatized' rocks. It is helpful in consequence to advise geology students that the study of thin sections is not only concerned with the identification of their mineral content. To do so would mean they could not see the wood for the trees. Accurate identification of the indi vidual minerals that form rocks is fundamental in their description but the analysis of their textures and habits is also essential. Study of textural features enforces constraints upon the inter pretation of the origin and history of a rock. The analysis of micro textures cannot and should never be an aim in itself, out must be sup ported by qualitative and quantitative correlations with theories of petrogenesis. The aim here is to help the reader to bridge the gap between his observations of rocks unqer the microscope and petrogenetic theories. The habits or architectures of crystals in rocks may resemble those studied by metallurgists and glass scientists. Analysis of micro textures is undergoing change engendered by comparisonS between manu factured and hence minerals. This can be seen from the increased number of publications dealing with crystal ~rowth or deformation processes at microscopic scales to which the name of 'nanotectonics' has been applied.

Along the Atlantic seaboard, from Scotland to Spain, are numerous rock carvings made four to five thousand years ago, whose interpretation poses a major challenge to the archaeologist. In the first full-length treatment of the subject, based largely on new fieldwork, Richard Bradley argues that these carvings should be interpreted as a series of symbolic messages that are shared between monuments, artefacts and natural places in the landscape. He discusses the cultural setting of the rock carvings and the ways in which they can be interpreted in relation to ancient land use, the creation of ritual monuments and the burial of the dead. Integrating this fascinating yet little-known material into the mainstream of prehistoric studies, Richard Bradley demonstrates that these carvings played a fundamental role in the organization of the prehistoric landscape.

This volume combines historical research and linguistic fieldwork with native speakers from across the United States to present the first comprehensive, up-to-date, scholarly dictionary of American placenames derived from native languages." "Linguist William Bright assembled a team of twelve editorial consultants - experts in Native American languages - and many other native contributors to prepare this lexicon of eleven thousand placenames along with their etymologies. New data from leading scholars make this volume an invaluable reference for students of American Indian culture, folklore, and local histories. Bright's introduction explains his methodology and the contents of each entry. This comprehensive, alphabetical lexicon preserves native language as it details the history and culture found in American indian placenames.

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. The volume is in a robust and handy size, with colour coded chapters for ease of use and quick reference in the field. 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.

The first edition of this book was published in 1965 and its French translation in 1966. The revised second edition followed in 1967 and its Russian translation became available in 1969. Since then, many new petrographie observations and experimental data elucidating reactions in metamorphie rocks have made a new approach in the study of metamor phic transformation desirable and possible. It is feIt that this new approach, attempted in this book, leads to a better understanding of rock metamorphism. The concept of metamorphie facies and subfacies considers asso cations of mineral assemblages from diverse bulk compositions as char acteristie of a certain pressure-temperature range. As new petrographie observations accumulated, it became increasingly difficult to accommo date this information within a manageable framework of metamorphic facies and subfacies. Instead, it turned out that mineral assemblages due to reactions in common rocks of a particular composition provide suita ble indieators of metamorphie conditions. Metamorphic zones, defined on the basis of mineral reactions, very effectively display the evolution of metamorphic rocks. Thus, the importance of reactions in metamor phic rocks is emphasized. Experimental calibration of mineral reactions makes it possible to distinguish reactions which are of petrogenetic sig nificance from those which are not. This distinction provides guidance in petrographie investigations undertaken with the object of deducing the physieal conditions of metamorphism. Within a metamorphie terrain, points indicating the same reaction constitute a line or a band, here designated by the term isoreaction-grad.
