             (excerpted from: Chapter 1 - Explanatory Text)

"Abstract

After nearly 30 years of growth in geochronologic knowledge, the originally
published age models for many older deep sea marine sections have become badly
outdated. In this report we present newly revised age models for Neogene
sediments from 94 DSDP holes. Biostratigraphic data for planktonic
foraminifers, calcareous nannofossils, diatoms and radiolarians, paleomagnetic
and other stratigraphic data were compiled from the original Initial Reports
volumes of DSDP. The Berggren et al. (1985) scale was used for the age of
magnetic reversals, and a variety of recent papers were used to establish a
standard modern set of calibrations for marine microfossil events to the
magnetic reversal scale. New age vs depth plots were made for each hole, and
for each a new line of correlation was created. All tabulated stratigraphic
data, new age models, and age depth plots are given as appendices to the
report."
