 note = {This paper reports 24 radiocarbon ages of charcoal samples which were excavated in 1993-1994 from Viroronga site (2 samples were from Ngaaitutaki site in 1992), Mangaia Island, Southern Cook Islands. Mangaia island is a small island (52km^2) located in 21°55' S, 157°55' W, being at the southeast end of the Cook Islands. Viroronga site is located at the west coast of the island. Viroronga can be classified into two sites. The southern part of Viroronga, V.R.-A site, was an ancient factory of stone tools and fishing gear. The northern part, V.R.-C, was a graveyard, where bone sets of 12 human bodies were excavated. Calibrated ^<14>C ages of the charcoal samples excavated from V.R.-A site indicate that the site had been occupied continuously for 3 centuries : 1150-1450cal AD. It is also suggested that there were two groups divided by a boundary between Layers 5 and 6 ; samples below the boundary give calibrated ages from 1150 to 1300cal AD, and samples above the boundary from 1300 to 1450cal AD. The calibrated ^<14>C ages of charcoal fragment samples collected around the ancient human bones from V.R.-C site suggested the site had been used as a graveyard since ca. 1400cal AD. However, a further examination from archaeology, anthropology and radiocarbon dating of the bone itself should be necessary to confirm the date, because these charcoal samples may not be directly connected with the human event such as burial or death., タンデトロン加速器質量分析計業績報告 Summaries of Researches Using AMS 1998 (平成10)年度},
