This is a book about the petrology of kimberlites. It is not about upper mantle xenoliths, diamonds, or prospecting for kimberlites. The object of the book is to provide a comprehensive survey and critique of the advances which have been made in kimberlite studies over the last twenty-five years. Kimberlites are rare rock types; however, their relative obscurity is overriden by their economic and petrological importance to a degree which is not shared with the commoner varieties of igneous rocks. Kimberlites are consequently of interest to a diverse group of earth scientists, ranging from isotope g~ochemists concerned with the evolution of the mantle, to volcanologists pondering the origins ...
This remarkable volume presents the first revision to the classification system of diamond-bearing rocks in over eighty years. Presenting the latest mineralogical data, this book offers a detailed description of the mineralogy and geochemistry of kimberlites, orangeites, and lamproites. Several hundred new analyses of minerals in orangeites are included. This volume follows the publication of Kimberlites, by R.H. Mitchell, and Petrology of Lamproites, by R.H. Mitchell and S.C. Bergman, concluding the trilogy.

Bats are dangerous to man. Right? Wrong. Here is the truth about chiroptera, the only mammals that fly, in a short, well-illustrated account based on solid research but intended for a general reader. Bats, of which there are about 850 species in the world, are maligned as carriers of rabies (largely untrue) and admired for their biosonar. Heir diversity is reflected in their diets: some eat fruit, some nectar and pollen, other fish, birds, frogs, or other bats. Although most eat insects, it is the three species of blood-feeding vampires which receive most public attention and around which much myth and superstition (and misconception) have evolved. In addition to their diet and habit, Fenton...
