Geologists have amassed data that indicate that islands have disappeared in the Pacific, a phenomenon that oral traditions of many groups of Pacific Islanders also highlight. This book explores the issue of vanished islands in the Pacific by bringing together the geology and the myths.

Hotspots are enigmatic surface features that are not easily explained in the framework of plate tectonics. Investigating their origin is the goal of this thesis, using field evidence collected in the Cape Verde Islands, a prominent hotspot archipelago in the eastern Atlantic Ocean. The approach taken is to document uplift of the islands relative to sea level and use the uplift features to test various models of hotspot development. Island uplift is thought to arise from the growth of the anomalously shallow seafloor on which the islands rest, known as the bathymetric swell, which is characteristic of hotspots. The work comprises a geological summary and detailed mapping of paleo sea level markers on Cape Verde. Isotopic dating of the markers shows that uplift on the islands over the last 6 Myr is up to 400 m, and that the uplift chronology varies among islands. Two processes act to raise the Cape Verde Islands. The dominant process is one that is local to individual islands. The regional, swell-related component is smaller, and possibly episodic. The observations provide strong constraints on swell development and on hotspot models.

This book gives a comprehensive presentation of the underlying oceanography and mathematics necessary to understand and develop a practical system of transmitters and receivers to interpret the behavior of the oceans. It covers the forward and inverse tomography problem, as well as numerous models for data interpretation. Also included is an epilogue outlining the history of tomographic techniques. It should prove a valuable resource to oceanographers and climatologists, as well as applied mathematicians and engineers interested in applications of fluid mechanics tools.

from volcanological and sedimentological perspec The idea for this book carne into being between 1981 and 1982 when J. V. W. came to Monash tives. One of our aims in the book is to provide geologists with a sound basis for making their own University to take up a Monash Postdoctoral Fellowship. During this period a short course on well founded interpretations. For that reason we facies analysis in modern and ancient successions cover not only concepts about processes, and the was put together, integrating J. V. W. 's extensive nature of the products, but also methods and volcanological experience in numerous modern approaches that may be useful in analysing both modern and ancient successions. Most importantly, volcanic terrains with R. A. F. C.

The enthusiastic response from the ing facies models for different volcanic settings. participants to the first short course, taught in May These models will, we hope, be useful as norms 1982, and to subsequent annual re-runs, encour for comparison for workers in ancient terrains. aged us to develop the short course notes into this The only publication which overlaps with this one book.
