Spatial and chronological database of archaeological relics and ruins in the Kinki District

申请的目的是，首先在古代文化和政治中心所在的Kinki区系统地标记新的放射性碳年代和考古年代学，利用新制作的比例尺重新洗牌这里的遗迹和废墟，其次建立并向公众发布它们的空间和时间序列数据库。已经或即将获得的结果是：开发了一种新的Li2C2方法，产生熔融的Li和碳化的样品的响应，从而合成苯，2.在大阪川内平原曾有内陆海或沼泽区扩张，泥炭沉积保存完好的内陆海或沼泽区，测定了一系列与弥合时期共生的木片的年代，并首次制作了弥合时期的放射性碳标尺。3.考察了液体闪烁光谱中闪烁液与样品苯的体积或重量比对放射性碳测年的实际影响。结果表明，无论溶液的总体积不同，含有相同浓度、相同比例、1.3以上闪烁体的溶液与样品苯具有相同的CPM/g和相同的外标光谱通道值。闪烁体溶液的加入减少了约0.5毫升的苯的本底，并导致质量系数显著增大，4.为放射性碳测年的考古用户出版了一个墓地，以与年代学合作推进，5.其他研究正在进行中。放射性碳测年被应用于恢复过去的沉积环境。对金基地区考古和地理数据库的框架进行了多边调查。我们的主页，包括数据库，将向公众开放。

The purposes stated in the application are, first to systematically mark with new radiocarbon dates and archaeological chronology in the Kinki District where ancient cultural and political centers were located, to reshuffle the relics and ruins here using the newly made scale, and second to make and release to the public their spatial and time-series database.The results already or nearly obtained are : a new Li2C2 method was developed to produce a response of melting Li and carbonized samples and consequently synthesize benzene, 2. a series of wood samples coexisting with chronologically used sherds of the Yayoi period have been dated in the Kawachi Plain of Osaka where an inland sea or marshy area had been extending and its resultant peaty deposits have kept relics and ruins well, and a radiocarbon scale of the Yayoi period has been made for the first time, 3. practical effects of the volumetric or weight ratio of scintillator solution to sample benzene in liquid scintillation spectrometry were examined for radiocarbon dating. It is concluded that solutions, containing the same concentrations, of the same ratio, 1.3 or more of scintillator solution to sample benzene show the same cpm/g and the same channel value of external standard spectrum, irrespective of different gross volumes of solutions. The addition of scintillator solution reduces background in 0.5 mL or so of benzene, and results in appreciably enlarged figure of merit, 4. an abecedarium for archaeological users of radiocarbon dating is published to advance in cooperation with chronological sciences, 5. the other studies are under way. Radiocarbon dating has been applied to restore the past sedimental environment. The framework for an archaeological and geographical databases of the Kinki District has been investigated multilaterally. Our homepage including the database will be opened to the public.
