King, K., Jr. and C. Neville. 1977.
Isoleucine Epimerization for Dating Marine Sediments:
Importance of Analyzing Monospecific Foraminiferal Samples.
Science, New Series, Vol. 195, No. 4284, pp. 1333-1335,
Mar. 25, 1977.
The rate of isoleucine epimerization in fossil planktonic
foraminifera is strongly species-dependent. Alloisoleucine/
isoleucine ratios of two species of the same age can vary
by more than a factor of 2. This finding, in combination
with the known temporal and spatial variability of
foraminiferal assemblages, demonstrates the critical
importance of basing geochronological studies of marine
sediments on monospecific samples. One rapidly epimerizing
species generates a calibration curve of potentially high
precision for dating sediments between the ages of about
50,000 to 400,000 years.
STUDY NOTES: Amino acid racemization (epimerization) in foraminifera
from western equatorial Pacific Ocean core V28-238.
Concentration and D-alloisoleucine/L-isoleucine values
from two taxa of foraminfera.
