This book is a substantially updated, revised and extended version of the book Volcanic Successions, published by Cas and Wright back in 1987. Divided into six major parts, it offers comprehensive information on magma properties; fragmentation processes; subaerial and subaqueous lava types and field textures; sub-volcanic intrusions; explosive or pyroclastic eruptions and deposits; surface sedimentary processes; hydrothermal alteration and lithification, and effects on volcanic rock textures; terminology and approaches to describing and mapping volcanic rocks and terrains; geology of volcanoes and facies models; volcanism and tectonic setting; and to conclude, volcanic-hosted resources. It is a highly up-to-date text, presenting a coherent flow of topics, together with excellent visual material to illustrate key points and deposit features. The new authorship team consists of Ray Cas, Guido Giordano and John Wright, all of whom have extensive experience across the complete spectrum of volcanological processes and deposit types discussed in this exciting new book. The authors approach the diversity of products in volcanic terrains as facies, and use facies analysis and interpretation as a means of constructing facies models for different volcanic settings and their resources. ­The book is intended as a textbook and research reference book for senior undergraduate and graduate students, researchers and professionals alike.
