From Gondwana to the ice age : the geological development of New Zealand over the last 100 million years Until about 100 million years ago New Zealand lay on the Pacific facing edge of the ancient supercontinent of Gondwana; the formation of our sedimentary rocks provides a fascinating view of the tectonic activity and changes since that time. This volume is the culmination of a comprehensive survey of New Zealands Cretaceous Cenozoic strata begun in 1978 and presents an up to date synthesis and interpretation of regional sedimentary information from a variety of sources; the study has been expanded to include large areas of the continental shelf and beyond. Extensive references and indexing complete this essential work a key resource for students professional geologists and enthusiastic amateurs Back cover
