Intraplate Volcanism: In Eastern Australia and New Zealand
R. Wally Johnson, Jan Knutson, Stuart Ross Taylor, Australian Academy of Science
Cambridge University Press, Nov 24, 1989 - Science - 408 pages
This is a major, definitive, landmark study of the young volcanoes of eastern Australia and parts of New Zealand. It deals with the rock types and origin of the volcanoes as well as the inclusions of the upper mantle and lower-crustal rocks found in the volcanic deposits. Fifty-nine authors contribute a wide range of chapters dealing with the significance of the volcanoes, the insights the area offers about the nature and origin of the earth's crust and the mantle beneath, and the geological evolution of eastern Australia and New Zealand over the past 70-80 million years. University academics and earth scientists in industry will be interested in this book, which will also serve as a highly useful reference work for undergraduate and graduate students.
