Figure 1. Location of Leg 165 drill sites (stars) and plate boundaries for the Caribbean plate (black lines: spreading centers are shown with two parallel lines, subduction zones with triangles attached, and strike-slip or uncertain boundaries as single lines). The plate boundaries are similar to those shown in Draper et al. (1994) and Meschede and Frisch (1998). The actual plate boundaries in several areas are more diffuse and complex than those shown. The solid dot gives the approximate location of the Galapagos hot spot.
