The Leg 29 sediment sequences are dominated by burrow-mottled, open-ocean biogenic sediments and by burrow-mottled, very fine-grained terrigenous sediments. Coarse detritus, primary sedimentary structures and turbidites are rare. Silicification and chertification is characteristic of the upper part of the fine-grained terrigenous facies. Clear-cut evidence for contemporary volcanism was recorded at only one site. The succession of facies generally reflects the gradual evolution of the three ocean basins by sea-floor spreading and the related development of the oceanic circulation patterns as they now exist.
