Revised Chronology of Neogene DSDP Holes from the World Ocean

by David Lazarus, Cinzia Spencer-Cervato, Milena Pika-Biolzi,  Jean Pierre
Beckmann, Katherina von Salis, Heinz Hilbrecht, and Hans Thierstein

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badly outdated.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.

The report is available in two forms.  A printed version (301 pp.; incl.
approx. 130 p. of tables and 157 black & white plots) is available from the
Ocean Drilling Program as Technical Note # 24.  Single copies are normally
free of charge.  Contact:

An interactive hypertext version, including full color plots, freely
downloadable computer readable versions of all files, etc, is available
from the NGDC via the World-Wide-Web.  The URL for this is:
http://www.ngdc.noaa.gov/mgg/geology/lazarus.html.  The NGDC version also
includes a downloadable copy of the Age Depth Plot program used to create
most of the figures in the report (runs only on Macs).

Questions, comments, and suggestions for improvements may be directed to me.
