PREFACE

Following their recognition by Gümbel (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 IUGS 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. Chapter 8 shows why more workers are coming to see lamprophyres as nearer the centre than the periphery of modem petrology. Chapter 9 briefly outlines reasons for the growing economic interest in lamprophyres. The Bibliography offers some 1,500 references. Appendix. A compiles the many abbreviations and symbols used. Appendix B aims to help non-specialist readers to steer their way through the terminological morasse formerly surrounding lamprophyres; geological terms cited in the text that do nor agree with the usage in Appendix B are placed in "quotes". Appendix C, a primary raison d’ étre of this book, documents and (with Figs.2.1-2.13) locates = 500 lamprophyre occurrences for the first time. Appendix D details the computerized database LAMPDA on which the book is largely based. Tables/Figures in the Appendices are referred to in the form 'Table C1' (i.e. Table C1 , Appendix C), whilst those in the text receive decimal numbers, e.g. 'Table 3.1'

The entire text and figures of this book were generated on a Macintosh® IIx microcomputer and Laser Writer® IINIX, for photographic reproduction by the publishers.

Constructive comments from interested readers, helping towards the eventual preparation of a more comprehensive, seasoned future edition, would be most welcome.
