The Jurassic of the Circum-Pacific [Paperback]

Not only is this the first comprehensive synthesis of Jurassic geology and palaeontology, but it is in fact the only one of its kind for any geological system.In this work, 60 specialists come together to discuss the regional occurrences of Jurassic rocks.

Not only is this the first comprehensive synthesis of Jurassic geology and palaeontology, but it is in fact the only one of its kind for any geological system.In this work, sixty specialists assembled to discuss the regional occurrences of Jurassic rocks around the Pacific rim. The tectonic setting, stratigraphical sequences, and fossil assemblages of the region are covered in detail; regional biozones based on palynonorphs, protistans, plants and invertebrates are defined; and super-regional standard zones based on ammonites are established. Numerous tables are used to document and illustrate intra- and intercontinental circum-Pacific correlations, and a large atlas illustrates more than 1,000 circum-Pacific index fossils.Introduction; Part I.
