Following their recognition by Gumbel (1874), lamprophyres were treated for an entire century as little more than obscure curiosities. Although this situation has changed recently, with a flowering of publications and active workers, lamprophyres remain almost the only group of igneous rocks which have not yet received attention in a dedicated monograph. In five exploratory reviews (1977-1987), the writer aimed to set out what was known about these rocks. The lUGS Subcommission on igneous rock systematics had meanwhile presented its nomenclatural framework (Streckeisen 1979). All this has now been overtaken by a recent explosion of interest, epitomized not least by lamprophyres' greater prominence in the 4th International Kimberlite Conference Proceedings. More data have become available since 1985 than over the entire previous century, and it is obviously impossible for such an extraordinary outpouring to be fully reviewed in this first, preliminary book. At the risk of dissatisfying some readers, therefore, this book concentrates on factual matters, and on a broad overview rather than minutiae. Because not even a world map of known lamprophyres was previously available, almost half the book is deliberately taken up by the first global lamprophyre compilation, and its commensurately extensive Bibliography. Such a compendium of largely objective information is believed to be of more immediate interest and lasting value than a premature pottage of petrogenetic polemic. Chapters 1-7 bring previous studies up to date, and concentrate on factual information.

This volume illustrates some of the significant aspects of magmatic activity from Devonian (408 million years ago) to early Permian (270 million years ago) times in SW England. This period covers the progressive development of the Variscan mountain-building episode, from initial basin formation to final deformation and the subsequent development of a fold mountain belt - the Variscan Orogen. Both extrusive (volcanic) and intrusive (plutonic) rocks are found in the orogen, and chart the various stages of its magmatic development. The sites described in this volume are key localities selected for conservation because they are representative of the magmatic history of the orogen from initiation to stabilization. Some of the earliest volcanic activity in the Devonian is represented by submarine basaltic and rhyolitic lavas developed in subsiding basins, caused by the attenuation of the existing continental crust. In some cases, extensive rifting and attendant magmatism produced narrow zones of true oceanic crust, whereas elsewhere basaltic volcanism is related to fractures in the continental crust at the margins of the basins. After the filling of the sedimentary basins, and their deformation caused by crustal shortening (late Carboniferous Period), further activity is manifested by the emplacement of the Cornubian granites and later minor basaltic volcanism in the early Permian. Accounts of the constituent parts of this history have enriched geological literature from the nineteenth century onwards, and have contributed to the advancement and understanding of magmatic and tectonic processes.

This book takes a new approach to writing about the past. Instead of studying the prehistory of Britain from Mesolithic to Iron Age times in terms of periods or artifact classifications, Tilley examines it through the lens of their geology and landscapes, asserting the fundamental significance of the bones of the land in the process of human occupation over the long durée. Granite uplands, rolling chalk downlands, sandstone moorlands, and pebbled hilltops each create their own potentialities and symbolic resources for human settlement and require forms of social engagement. Taking his findings from years of phenomenological fieldwork experiencing different landscapes with all senses and from many angles, Tilley creates a saturated and historically imaginative account of the landscapes of southern England and the people who inhabited them. This work is also a key theoretical statement about the importance of landscapes for human settlement.

Volume 26 of Reviews in Mineralogy provides a multidisciplinary review of our current knowledge of contact metamorphism. As in any field of endeavor, we are provided with new questions, thereby dictating future directions of study. Hopefully, this volume will provide inspiration and direction for future research on contact metamorphism. The Mineralogical Society of America sponsored the short course on Contact Metamorphism, October 17-19, 1991, at the Pala Mesa Resort, Fallbrook, California, prior to its annual meeting with the Geological Society of America.

This book represents an innovative experiment in presenting the results of a large-scale, multidisciplinary archaeological project. The well-known authors and their team examined the Neolithic and Bronze Age landscapes on Bodmin Moor of Southwest England, especially the site of Leskernick. The result is a multivocal, multidisciplinary telling of the stories of Bodmin Moor—both ancient and modern—using a large number of literary genres and academic disciplines. Dialogue, storytelling, poetry, photo essays and museum exhibits all appear in the volume, along with contributions from archaeologists, anthropologists, sociologists, geologists, and ecologists. The result is a major synthesis of the Bronze Age settlements and ritual sites of the Moor, contextualized within the Bronze Ages of southwestern and central Britain, and a tracing of the changing meaning of this landscape over the past five thousand years. Of obvious interest to those in British prehistory, this is a substantial presentation of a groundbreaking project that will also be of interest to many concerned with the interpretation of social landscapes and the public presentation of archaeology.
