内容記述 | An aim of the present study examine the relationship between aspartic acid racemization age and radiocarbon age in fossil planktonic foraminifera Pulleniatina Obliquiloculate for the application of the age determization by the aspartic acid racemization over the 〜20,000 years. Two sedimentary core samples were collected from SC-8 and SC-9 in the equatorial wastern North Pacific by a box corer. The core samples were cut into slice with 1cm thickness. Pulleniatina Obliquiloculate test was separated from the core samples by wet sieving using a screen with 60 mesh and under the optical microscope, and analyzed for the determization of the D/L ratio of aspartic acid and radiocarbon age. When ln[(1+D/L)/(1-D/L)] of aspartic aicd was plotted against ^<14>C age of the foraminiferal test, first order reaction rate constant (k) for the racemization of aspartic acid was calculated to be 1.01×10^<-5>yr^<-1>, indicating that racemization reaction of aspartic acid can be applied to determination the age of the marine sediment samples ranging over 10^5yr. | |||||
