The materials in this contribution are components of a multidisciplinary, comprehensive analysis of the geology and geomorphology of Barbados by Robert Speed, who passed away in 2003 shortly before finalizing this work. Basement rocks on Barbados are assigned to two Paleogene tectonic complexes that formed within or above an active subduction complex. The basement rocks are overlain by Quaternary rocks and sediments, and Speed’s studies of these younger materials are the focus of this volume. The island’s marine terraces, modern shore zone, modern marine sea cliffs, stream networks, and landslides are analyzed in detail. Uplift rates that were calculated at 71 sites, and dozens of 230Th dates of Pleistocene limestone are presented here for the first time. The accompanying CD-ROM includes a set of twelve 1:10,000 geological maps of Barbados, West Indies; four associated cross sections that transect the island; and a three-part appendix, which contains advanced drafts of two unpublished manuscripts.
