| contents | Lower Cretaceous and Tithonian sediments were sampled for magnetostratigraphy at six holes (Holes 638B, 638C, 639A, 639D, 640A, and 641C). Magnetic polarity chrons were assigned to polarity zones using biostratigraphic constraints. In Holes 638B and 638C, polarity Chrons M3 and perhaps Ml are present in the upper part, M4 and M5 are apparently absent, M6 through M9 are poorly represented, M10 and M10N are apparently absent, and Ml 1 and M12 are tentatively assigned to the lower part. Strata in Holes 638B and 638C dip toward the south. In Hole 639A, polarity Chron M13 is well documented and M12A may be present. In Hole 639D, polarity Chrons M19 through M21 may be present, but the data is poor. Hole 640A had inadequate recovery to identify polarity chrons. In Hole 641C, polarity Chron MO is well documented and occurs significantly above the nannofossil marker of the Barremian/Aptian boundary; comparison to Italian magnetostratigraphy implies that this nannofossil datum is timetransgressive. |
