This volume presents the initial scientific results of Deep Sea Drilling Project Leg 78A, which cored the seaward portions of the Lesser Antilles subduction complex on the eastern edge of the Barbados Ridge (Fig. 1). Leg 78A was basically a drilling experiment to penetrate the toe of a particular type of accretionary complex at a convergent margin and reach materials whose eventual fate will either be subduction or underplating of the accretionary pile. The cores obtained document with considerable clarity the structure and style of deformation of the zone of active sediment accretion. A variety of downhole measurements provide important indications of the actual mechanics of faulting and deformation in the area. In this chapter we present both the topical and regional background for the drilling, list the principal objectives for the drilling at each specific site, and provide the reader with general information necessary to understand the details of core-handling procedures, lithologic descriptions, and biostratigraphy. The volume itself is divided topically into groups of related chapters, beginning with the results of precruise and postcruise surveys and data syntheses, proceeding to site reports, then to chapters devoted specifically to studies in sedimentology, paleontology, downhole experiments, and so forth. The volume concludes with a summary chapter.
