Summary: Various stratigraphic and paleoenvironmental results arise from mineralogical, geochemical and micromorphological investigations on Late Cretaceous and Cenozoic sediments recovered by the Deep Sea Drilling Project in the West Pacific: (1) Stratigraphic correlations, (2) Climate and paleocirculation, (3) Regional and global tectonics. Neogene sediments of the Lord Howe Rise area reflect closely the relationship between the evolution of the Antarctic ice sheet and related aridification stages, and the atmospheric and oceanic circulation pattern since 14 my. The post-Eocene deposits around New Zealand express a sequence of tectonic events and of relaxation stages, associated with changes in the circulation regime.
