contents The results of inductively coupled argon plasma (ICAP) chemical analyses carried out on some 300 core samples from Ocean Drilling Program Sites 834, 835, 838, and 839 are presented. These sites were drilled during Leg 135 in the Lau Basin. The data are compared with total gamma (SGR) wireline logs at Sites 834 and 835. Pliocene (Piacenzian) nannofossil Zone CN12, which has been identified at Sites 834 and 835, is examined in detail using spectral analyses on core and wireline logs. The potassium and calcium concentrations from the core material were used to calculate an objective depth-to-geological time stretching function, which improved the stratigraphic correlation between sites. The integrated use of chemical analyses, wireline-log data and paleomagnetic results improved confidence in the correlations obtained. Although no significant sedimentation periodicities were obtained from the two sites, a common concentration of energy between 30 and 60 k.y. was recorded.
