项目摘要

The excavation units of totally 12 by 4 m were set adjusting to the area excavated till the fourth term. This year's research reached Layer V. The feature of shell concentration was encountered in Layer IV, which has been interpreted as the sterile intermediate layer. There were Tridacna shell adzes, tools made of Chiragra spider conch (Lambis lambis) and bivalves and mammal bones were scarce.More than fifty Tridacna shell adzes were collected with the various types of shape at Arafu Site including surface collection. Tridacna shell also produces several other types of tools along the variation of its subspecies, as like chisels, This site contains the considerable amount of flakes and debitage of several shell species. These shells are supposed to have been brought in the site at the end of manufacturing process, considering the wide range of shell utilization. Turbo argyrostomus and Trochus niloticus Tectus together occupies the 80% of total amount of shells and were though to have been the main concern of subsistence. Turbo argyrostomus shows the drilling on their shells. Uniformity and standardization were observed on the shape of perforation and the form of shaped -out lower parts of shell. These characteristics suggest other use of this shell than diet.The research of this site is stilt ongoing. The characters of table corals and pit features still remain unresolved and require further investigations. The report of research from the first through fifth term is coming on July 2003.

根据第四期开挖区域，设置了总计12 × 4 m的开挖单元。今年的研究达到了第五层，在第四层遇到了贝壳集中的特征，这被解释为不育的中间层。在阿拉福遗址，除出土的斧形斧外，还发现有斧形斧，斧形斧的材质主要为契拉格拉（Chiragra）、蜘蛛螺（Lambis lambis）和双壳类，哺乳动物骨骼等，数量较少。Tridacna壳也产生其他几种类型的工具沿着它的亚种的变化，像凿子，这个网站包含了相当数量的薄片和debitage几个壳物种.考虑到髋臼杯的广泛使用，这些髋臼杯应在制造过程结束时带入现场。银口Turbo argyrostomus和Trochus niloticus Tectus共同占据了贝类总量的80%，被认为是主要的生存问题。Turbo argyrostomus展示了它们壳上的钻孔。观察到穿孔形状和壳体下部成形形状的均匀性和标准化。这些特征表明这种贝壳的其他用途而不是饮食。这个网站的研究仍在进行中。桌珊瑚的特征和坑的特征仍然没有得到解决，需要进一步的调查。第一至第五学期的研究报告将于2003年7月提交。
