Age Determination of the Kawagodaira Volcanic Eruption in Japan by 14 C Wiggle-Matching
The Kawagodaira Volcano is located on the northwest slope of Amagi Volcano on the Izu Peninsula of central Japan. The fine pumice that erupted from Kawagodaira Volcano is widely distributed in the central and western parts of the Japanese mainland. Here, we report an accurate eruption age determined by radiocarbon wiggle-matching of a Japanese cedar timber excavated from the pyroclastic deposit at the pumice flow terminal of Kawagodaira Volcano. …
Regional Offset of Radiocarbon Concentration and Its Variation in the Korean Atmosphere from AD 1650–1850
A series of annual tree-ring measurements has been performed in order to reconstruct the radiocarbon concentration variation in the Korean atmosphere from AD 1650 to 1850. The absolute ages of the samples were determined using dendrochronology. Alpha-cellulose extraction was applied to prepare the tree-ring samples for precise 14 C measurement. The 14 C concentrations of the tree rings were then plotted with the dendrochronological ages and showe…
A New 1MV AMS Facility at Kigam
A 1MV AMS was installed in KIGAM (Korea Institute of Geoscience and Mineral Resources). After 4 months of installation, the AMS started normal operation from January 2008. This multi-element AMS was developed by HVEE to measure 14 C, 10 Be, and 26 Al. The results of an acceptance test demonstrate that this machine is capable of routine 14 C age dating and of measurements of other radioisotopes in terms of accuracy and precision as well as the bac…
Establishment of Chemical Preparation Methods and Development of an Automated Reduction System for AMS Sample Preparation at Kigam
Many previous studies on the sample preparation of various kinds of radiocarbon dating samples by accelerator mass spectrometry (AMS) have been examined at KIGAM (Korea Institute of Geoscience and Mineral Resources) and our own procedures have been established. Furthermore, an automated reduction system has been developed. The volume of the reduction region was minimized to improve the reduction yield, and air-actuated pneumatic valves and soleno…
Radiocarbon Dating of the Mansuri Paleolithic Site, Cheongwon, Korea
Construction of a new science complex in Osong, Cheongwon-gun, Korea, has allowed the investigation of 14 different Paleolithic localities, excavated during 2005–2007. Here, we investigated localities 1 and 12 of the Mansuri Paleolithic site to obtain chronological information using radiocarbon dating. The soil deposition rates varied from 0.09 to 0.15 mm/yr over the period ranging from 33 to 31 kyr BP for locality 1. Locality 12 samples were mor…
