Background Barbados The Barbados accretionary complex is located in the Caribbean where the north American Plate (Figure 2-1) is being subducted beneath the Caribbean Plate at a rate of about 2 cm/yr in an east-west direction (DeMets et al., 1990). Active accretion of sediments at the Barbados accretionary complex takes place at the eastward end of the complex. The complex is partially exposed above sea level at Barbados Island (Figure 2- 1). At the location of DSDP and ODP drilling, the incoming sediments are predominantly clay and claystones. A w ** SDSDP'ODP dril T.1e. \\ \ ^ area ,o Depth A45. .45 1 Site (in She 1047 Ste k10 --..---.
