Figure F5. Summary of recovered lithology at drill sites on the incoming plate off Guatemala (DSDP Site 495) and Costa Rica (Site 1039) as well as on the Costa Rica margin (Sites 1040 and 1043). Note the similarity of incoming sediment sections at Sites 1039 and 495, as well as the repetition of the Site 1039 section below the décollement at Sites 1040 and 1043. Lithologic columns are modified from Kimura, Silver, Blum, et al. (1997).
