About this book
In the last ten years offshore mineral exploration programmes have increasingly concentrated on the 200 mile Exclusive Economic Zones adjacent to coastal states. This book gives an integrated treatment of the various mineral types occuring in these zones, their genesis, distribution and economic importance. The book opens with a broad overview of the subject and discusses the legislative issues relevant to marine and mineral exploitation. Chapters then deal in turn with aggregates, placers, precious coral, phosphorites, manganese nodules, cobalt-rich manganese crusts and hydrothermal deposits. An international set of case studies illustrates each type of deposit, many studies based on the author's own experience in marine mineral evaluation programmes around the world during the past 25 years. This book should be of interest to economic and mining geologists, marine geologists and mineral economists.

Cronan's sober discussions of resource potential put all these mineral deposits into a proper perspective. ... the book successfully meets the objectives of the series to which it belongs. It is well written, has a substantial list of references and is well indexed. I recommend it to oceanographic and geological libraries and to individuals with a broad interest in marine mineral resources. - Ocean Challenge; The book is backed by a long list of references to mainly recent works on the subject and serious readers should be able to add further to their knowledge... Marine Minerals in Exclusive Economic Zones adds significantly to our knowledge yet shows how much more exploration is required. It can certainly be recommended. - Underwater Technology; ...another first-class book on marine mineral deposits, this time with focus on resources within the several exclusive economic zones...the sense of realism prevails throughout the book...we are pleased to recommend David Cronan's new book for all marine mineral enthusiasts. - Marine Mining; an enjoyable read... an essential undergarduate library text. - Geological Magazine; The book is an excellent up-to-date reference source for teachers, students, and for those practitioners interested in the economic potential of seafloor deposits, including commercial companies... The reader has access to a broad range of annotated diagrams and many bench-mark references. - Marine Geology; The author of ... is probably the leading British expert in the ever-broadening field of marine minerals... the book successfully meets the objectives of the series to which it belongs. It is well written, has a substantial list of references and is well indexed. I recommend it to oceanographic and geological libraries and to individuals with a broad interest in marine mineral resources. - Ocean Drilling Program
