Archaeological Research on the Lower Cagayan River - Study on the Historical Process of Hunter-Gatherer/Farmer Interdependent Relationship.

1.在为期三年的研究期内，继续对卡加延河下游的贝冢进行发掘，在卡加延河沿岸发掘了8个贝冢和1个内陆贝冢。利用出土的地层学、文物学等资料建立地方年表。从卡加延河河口往上50公里处都有考古遗址的记录。在圣洛伦索贝壳垃圾场，通过继续挖掘900平方米，收集了贝壳处理和贝壳垃圾场形成模式的数据。在这个遗址中还发现了属于不同时代的三种不同的埋葬习俗。考古学家获得了名古屋大学AMS的C14数据。贝壳存款下的粉砂层的C14数据为3000 Cal.BP，贝壳层为3000 - 1000 Cal. BP。考古学家还分析了人类骨骼的古饮食分析，他们发现，人B ...更多信息 生活在贝冢中的生物有依赖陆生哺乳动物的倾向.对史前稻田的研究是为了研究制造贝冢的人的生存。弥生时代考古的稻田发掘专家参与了我们的研究，他们在河岸贝壳贝冢后面的三个地点发现了史前稻田。同时收集了水稻田的植物蛋白石数据进行验证.利用遗址出土的陶器建立了地方年代学：红泥陶纹饰阶段→红泥陶无纹饰阶段→黑泥陶纹饰阶段→黑泥陶无纹饰阶段→日用陶瓷和褐泥陶阶段。利用考古学资料，构建了史前菲律宾狩猎采集社会与农耕社会相互依存关系的历史过程模型和低地社会政治整合过程模型。少

1. The continuation of excavations of shell middens on the Lower Cagayan River, twelve sites of eight shell middens on the riverbank of Cagayan River and one inland shell midden were excavated for the three years research term. The data from excavations like stratigraphy and artifacts were used for the establishment of local chronology.2. The archaeological sites could be recorded until the 50km up from the river mouth of Cagayan River.3. In San Lorenzo Shell Midden, the data on the shell disposal and shell midden formation pattern were gathered by the continuations of excavations of 900 m^2. Three different burial practices belonging to the different ages were also revealed in this site.4. C14 data using AMS at Nagoya University were acquired by the archaeometrists. C14 data from the silt layer under shell deposit are 3000 Cal.BP, and shell layer are 3000 to 1000 CaLBP. Also the archaeometrists analyzed the human bones for the palaeodietary analyzes and they revealed that the people b … More uried in the shell middens had the tendency to relied on the terrestrial mammals.5. The research on the prehistoric paddy field was performed for the subsistence study of the people who made shell middens. The specialists of paddy field excavation of Yayoi Period archaeology were participated to our research and they revealed the prehistoric paddy fields in the three sites behind the riverbank shell middens. The plant opal data were also collected to verify the paddy field.6. The local chronology using the potteries collected from the sites were established as follows ; the decorated red-slipped pottery phase → non- decorated red-slipped pottery phase → decorated black pottery phase → non-decorated black pottery phase → trade ceramics and brown pottery phase.7. The models of historical process of interdependent relationships between hunter-gatherer and farmer societies, and political integration process of the lowland societies of the prehistoric Philippines were built using the archaeological data revealed by the research.
