Figure F15. Correlation of lithostratigraphic units between Sites C0013, C0014, and C0016. The top of the silicified volcanic sediment represents the main correlative marker between the sites. The sudden change in dip between Site C0016 and the other sites is consistent with faulting, most likely extensional collapse of a volcanic flank by mass wasting, as seen at Site C0017. The entire section drilled at Site C0013, 0–54.5 mbsf, was hydrothermally altered, with a surface layer of 24 m of pumice altered to gray hydrothermal mud.
