thrusters and hydrophones were pulled at 0100 h 22 July. Total time spent on Hole U1420A was 189.25 h. Lithostratigraphy A lithologic summary of Site U1420 is shown in Figure F5. The total depth of Hole U1420A was 1014.5 m core depth below seafloor (CSF-A). Recovery from 58.2 to 448.5 m CSF-A was <10% but improved deeper than 448.5 m CSF-A, where several cores were collected with recovery between 30% and 94%. Total core recovery for the entire site was 14%. Additionally, numerous drilled rocks and washed clasts were recovered without a supporting matrix lithology. Cores containing mostly drilled rocks and washed clasts include 341-U1420A-10R through 47R, 49R, 52R through 57R, 75R through 79R, and 85R. The limited sediment recovered at Site U1420 contains seven facies. Detailed facies descriptions, information about common marine microfossils, facies occurrence in lithostratigraphic units, and tentative interpretations about depositional environments are summarized in Table T2. The dominant facies (F4f and F4e) are very dark gray (N 3) to dark gray (N 4) clast-rich and clast-poor diamict. Photographs of the most common facies are shown in Figure F6. Based on characteristic facies associations, three lithostratigraphic units were defined (Table T3).
