This volume deals with the geology of the northeastern part of the Pacific ocean and the adjacent parts of the North American continental margin. The areal coverage is from the margin west to the Hawaiian Seamount chain, and south to the equator.
The volume comprises several major sections containing related chapters: regional bathymetry and tectonics (Chapters 2 to 4 and Plates 1 and 3); Spreading ridge systems (Chapters 5 to 11 and Plate 4); Hawaii-Emperor and other seamount chains (Chapters 12,13, and Plate 5); sediments of the northeast Pacific (Chapters 14 to 19, and Plate 2); and Pacific continental margins of North America (Chapters 20 to 28, and Plate 6). In the paragraphs below are a few introductory remarks about each chapter, which may help readers to find their way.
Figures & Tables
This new synthesis includes a section on plate kinematics, documenting the basis for a new interpretation of the magnetic anomaly patterns. It also includes: six chapters on various aspects of tectonics, petrologic characteristics, and hydrothermal processes of active ridges from the Galapagos Rift to the Juan de Fuca Ridge; a section on mid-plate volcanism, including the Hawaii-Emperor chain; five chapters on various aspects of northeastern Pacific sedimentary regimes; and nine chapters on the geology of the Pacific continental margin from the Aleutians to Guatemala, seen from the perspective of marine geology. Three separate oversize plates illustrate the bathymetry of the northeast Pacific; two more on the same base show distribution of sediment samples and types and magnetic anomaly data and tectonic interpretations; and others include a synthesis of the geology and bathymetry of the Hawaiian Islands, details of bathymetry along parts of the East Pacific Rise, and a major seismic profile across the Pacific margin of Guatemala.
