The Woodlawn orebody is located in eastern New South Wales, Australia. It is one of an important class of massive, copper-lead-zinc, stratiform volcanogenic mineral deposits and has reserves of about 10 million tonnes of ore. Deposits such as Woodlawn are the object of considerable worldwide exploitation effort because they yield the highest rate of return on mining investment with modest capital requirements. This detailed geophysical case study contains individual contributions by professionals from diverse backgrounds (industry, government and university) and includes the latest geophysical methods. It is the only detailed geophysical study of an economic sulphide deposit ever undertaken for educational purposes

Why another book about Ore Deposits? There are a number of factors which motivated us to write this text and which may provide an answer to this question. Firstly our colleagues are predominantly mining engineers and minerals processing technologists, which provides us with a different perspective of ore deposits from many academic geologists. Secondly we have found that most existing texts are either highly theoretical or merely descriptive: we have attempted to examine the practical implications of the geological setting and genetic models of particular ore deposit types. We have written the text primarily for undergraduates who are taking options in Economic Geology towards the end of a Degree Course in Geology. However, we hope that the text will also prove valuable to geologists working in the mining industry. The text is to a large extent based on a review of the existing literature up to the end of 1984. However, we have visited most of the mining districts cited in the text and have also corresponded extensively with geologists to extend our knowledge beyond the published literature. Nonetheless writing a text-book on Ore Deposits is a demanding task and it is inevitable that sins of both omission and commission have been committed. We would therefore welcome comments from readers which can be incorporated in future editions.

This handy pocket-sized book provides practical information and assistance to anyone engaged in small-scale surveys on the ground. The 3rd edition updates the considerable changes in instrumentation, and far-reaching developments in applications that have occurred since 1996. New sections include details on Ground Penetrating Radar, VLF and CSAMT/MT, GPS navigation, electromagnetic methods of conductivity mapping, capacity coupling, and audiomagnetotellurics (AMT).
