1. Book review . Fundamentals of fracture mechanics, by J.F. Knot. London, Buterworths, 1981 (reprint). Reviewer: G. Leadbeater The present reviewer approached the above book as a relative novice on the intricate details of fracture mechanics. Thus, the review is based to a great extent on how easily the information presented can be assimilated and understood, and how the book's format and content facilitate this. Note was taken of the preface comments about jumping ahead, in chapters, to ease understanding, and this was found to be a common occurence. 2. New publications Mechanical testing.

Book news 1. Book reviews ? Prospecting in areas of desert terrain. London, The Institution of Mining and Metallurgy, 1985. 283 pp. £28 (members £25,20). Reviewer: J.S. Mostert This publication records the proceedings of a con¬ference convened to deal exclusively with prospecting in areas of desert terrain. The meeting, organized jointly by The Institution of Mining and Metallurgy (London) and the Ministry of Energy and Mines, Morocco, was held in Rabat from 14th to 17th April, 1985, and generated considerable international interest. Exploration cam¬paigns and case studies of successful discoveries in the desert areas of more than 14 lands are described. Since large areas of South Africa, Botswana, and Namibia are characterized by and and semi-arid terrains, this publication should be of considerable interest to explorationists and mining engineers engaged in the search for and development of mineral deposits in southern Africa. The fact that the desert terrains of southern Africa are host to a number of important base-metal (Aggeneys, Gamsberg, Prieska, and O'Okiep) and diamond deposits (Orapa, Jwaneng) has ensured continued interest in these areas from the viewpoints of exploration and mining.

1. Book review • World mineral statistics 1974 to 1978. Production: Exports: Imports. London, H.M.S.O., Institute of Geological Sciences, 1980. (Reviewer: R. P. King) This edition is the third in a regular series prepared by the Institute of Geological Sciences. It is a useful compilation of statistics on the production, export, and import of fifty-eight different mineral commodities. Each mineral is listed by country, and a table is provided for the annual production, the annual imports, and the annual exports for each commodity included. However, some commodities are treated in considerably more detail; for example, aluminium and bauxite have tables under the following headings: Production of Bauxite, Production of Alumina, Production of Primary Aluminium, Exports of Bauxite, Alumina and Aluminium, Imports of Bauxite, Alumina and Aluminium. The information presented is the latest official information available from primary sources; the compilers have not relied on data from secondary compilations. This publication will be of considerable assistance to all who are concerned with the trading of mineral commodities and their production.

1. Book reviews . Rudiments of mining practice, oy C.E. Gregory.Clausthal-Zellerfeld (West Germany), Trans Tech Publications.OS$24.Reviewer: A.N. BrownProfessor Gregory has had a wide experience of hardrockmetalliferous mining throughout the world, beinga well-known academic who has taught at many universitiesin the Western World. His basic training was obtainedin his native land of Australia. In this publication he identified the need for a basic, simple book on miningpractice to provide new students of mining with a backgroundto their studies. He also designed the book to providea background to persons operating on the fringesof the industry such as students of economics and journalists.The text extends to only some 120 pages, and containsa sufficient number of monochrome sketches, diagrams,and photographs. It is written in a straight-forward, easyto-read style. The book contains an index and elementarytable of conversion from imperial to SI (metric) units,and there is also a glossary of mining terms that mostreaders would find useful.The author has succeeded in keeping the contentssimple, as indicated by the title. However, after each chapter, there are references to further recommendedreading. The book could be useful in the South African context, although the coverage of coal and opencast mining operations is slender.

Interpretation of Leached Outcrops, by Roland Blanchard. Published by Nevada Bureau of Mines, University of Nevada, Reno, Nevada, 89507, 1968, 188 pages. Price $7.50 (R5.40). This book contains a summary of the author's knowledge of leached outcrops, derived from some 30 years' experience as a geologist operating mainly in the United States of America and Australia. Part 1 of the book provides a comprehensive coverage of the various processes and substances involved in the oxidation of many minerals, under different climatic conditions, to form the final leached products. In Part 2, details are given of the appearance and composition of the oxidation products of the following minerals: pyrite, pyrrhotite, arsenopyrite, cha1copyrite, cha1cocite, bornite, tetrahedrite, oxidized copper minerals, galena, cerussite, sphalerite, molybdenite, chromite, hematite, magnetite, manganite, pyrolusite, calcite, siderite, fluorite, salite and supergene silica. The illustrations, the black and white photographs and the colour plates of oxidation products are of a high standard. The material is presented in a logical order and in terms which are not over-technical; hence it is useful to persons other than trained geologists. Despite the advances in geophysical and geochemical prospecting, the location and interpretation of gossans remains an important method of discovering ore bodies, particularly so since the correct interpretation of a leached material can prevent the fruitless and expensive prospecting of an underlying body of uneconomic concentration. Therefore it is considered that this volume will be a valuable addition to the libraries of universities, exploration companies and geologists. It is of interest to note that the author, who died in 1966, presented a paper, under the same title as this book, to the Chemical, Metallurgical and Mining Society of South Africa in 1939. For this work he was awarded the Society's Gold Medal. W.T.S.
