These have yielded 47 age datums from late Pleistocene to early Miocene, and thus a robust age-depth curve. The flora indicates subtropical high-productivity conditions, whereas the faunas show some mixing of warm and cool subtropical species. Magnetic intensities are weak in the upper 200 mbsf and below that decline to the noise level of the machine. A reasonable stratigraphy can be detected in the upper 200 mbsf with most reversals down to the base of C3n.4n at 5.23 Ma. Physical properties at this site are very uniform with slow and slight increases in density.
Magnetic susceptibility is relatively featureless.
The gamma record exhibits more character which will be worth examining by spectral methods. The upper part of the hole is marked by sulphate reduction with decline of SO4 to zero at 200 mbsf and increase of methane in the zone of methanogenesis below that to 500 mbsf. Most other properties are related to these processes - alkalinity and ammonia increase in the upper 200 m and resulting Ca decrease due to carbonate precipitation, followed by Ca increase and carbonate dissolution in the zone of methanogenesis. Silica increases steadily downhole but sharply decreases in the bottom 40 m where particularly hard mudstone is encountered, probably due to incipient silica cementation. Site 1125 proved the equal of the other sites on this leg in its capacity to surprise us.
