This chapter presents the sedimentary story of the California Continental Borderland. We describe the form of the borderland, examine its dimensions and context, review its geologic history, and examine the sources of sedimentary materials. We then review the oceanographic, climatic, and bathymetric factors controlling the distribution and accumulation of particulates in the depositional centers. We conclude by summarizing a set of basin models and point out some possible ancient analogs. As we proceed, major research questions are noted.

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.
