Abstract:
Paleomagnetic studies on sediments recovered during Leg 136 have yielded a polarity reversal sequence that can be compared with the global magnetic reversal time scale to establish a sedimentation rate for Hole 842B. This sedimentation rate is substantially higher than that normally observed in the central Pacific basin probably as a result of the contribution of volcanic ash to the normal pelagic sources of sediment. The basalt samples from the oceanic crust at Site 843 have been used to determine a paleolatitude of 10.2°S for the 110±2 m.y.-old crust from this site. Detailed studies of the polarity transitions yielded few intermediate directions, but these few records provide support for the "Americas" transitional path observed at other continental and marine sites in Europe and North America.
