项目摘要

(1) Surveys of Micro-burning in Palaeolithic FeaturesIn order to investigate features which are thought to have received only small amounts of heat, archaeological excavations and geophysical surveys were conducted on Palaeolithic cultural layrs at the Onbara 1 site in Okayama Prefecture and the Mattobara site in Niigata Prefecture. At Onbara 1, five concentrations of charcoal were discovered from Cultural Layr O which dates to about 20,000 BP.Palaeomagnetism, ESCA,ESR,and volcanic glass methods were used to determine if these features had been burnt. Stone tools and small rocks were found associated with the charcoal concentrations suggesting that these were the remains of hearths made by Palaeolithic people. In general the geophysical surveys tended to support this assumption, but results varied depending on the method of analysis. An experimental campfire was built on the same soil stratum and results compared. Analysis was also conducted on Jomon period hearths where the soil was reddened and there was no doubt that burning had occurred. Results from these features were then compared with the Palaeolithic charcoal concentrations.(2) Surveys on the Effects of Heat Noise' on Archaeological FeaturesExcavations and geophysical surveys were conducted at the Midoro, Konzoku, Ohgakeyama and Miyagatani sites in Hiroshima Prefecture in order to determine the effects of possible interference from burning. The first three of these sites are iron production sites. At the iron production sites, results obtained from pre-excavation Ground-Penetrating Radar, magnetometer and resistivity surveys corresponded well whih those from the actual excavations, confirming the effectiveness of geophysical methods for determining the location of smelting furnaces and other similar features. further research is needed on charcoal production sites.

(1)旧石器时代遗址中微燃烧的调查为了调查被认为只受到少量热量的特征，对冈山县Onbara 1遗址和新泻县Mattobara遗址的旧石器时代文化层进行了考古发掘和地球物理调查。在翁巴拉1号，在大约20,000年前的文化层O中发现了五种浓度的木炭。使用古地磁、ESCA、ESR和火山玻璃方法来确定这些特征是否被烧毁。发现了与木炭浓度有关的石器和小石头，这表明这些是旧石器时代人制作的炉子的遗骸。一般来说，地球物理调查倾向于支持这一假设，但结果因分析方法的不同而不同。在相同的土层上燃起了篝火，并对结果进行了比较。还对朱蒙时期的火炉进行了分析，那里的土壤变红了，毫无疑问发生了燃烧。然后将这些特征的结果与旧石器时代的木炭浓度进行比较。(2)热噪声对考古特征的影响调查广岛县的Midoro、Konzoku、Ohgakeyama和Miyagatani遗址进行了洞穴和地球物理调查，以确定可能的燃烧干扰的影响。这些地点中的前三个是铁生产地点。在铁生产现场，开挖前的探地雷达、磁强计和电阻率测量的结果与实际开挖的结果吻合得很好，证实了地球物理方法确定冶炼炉位置和其他类似特征的有效性。还需要在木炭生产现场进行进一步的研究。
