EXCAVATIONS OF LAL-LO SHELL MIDDENS

(1)河岸贝贝冢的挖掘工作一直在继续，以获得人工制品来建立当地的年表。根据研究结果，将其年代序列划分为红泥陶I年代等四个时期。根据研究结果，将该地区的时间序列划分为红泥陶I期、红泥陶II期、黑陶I期、黑陶II期四个时期，并阐明了时间序列的变化与聚落形态的变化相对应。(2)对C14测年、动物区系和植物区系遗迹的鉴定、动物区系和植物区系遗迹的季节和生境鉴定、地质和花粉样品的科学分析不断进行。根据分析结果，我们可以得到理解史前环境开发和生存策略变化模式的关键，即贝冢的形成是由Cagay的沼泽环境向河流环境的变化开始的 ...更多信息 一条河。后期，下游贝冢数量增加。(3)在两个河岸遗址中，从贝冢下的淤泥层中发现了人类骨骼遗骸。菲律宾国家博物馆目前正在进行史前饮食的同位素分析和体质人类学分析。(4)同位素分析结果出乎意料地阐明了史前拉罗族采贝者的食物依赖于陆生哺乳动物。(5)地质和花粉研究小组在河岸和内陆地点进行了钻探，并获得了每个地点的地质环境数据和花粉样本。(6)通过对位于丘陵地区的洞穴遗址的发掘，收集到了无定形薄片和红片陶片。在河岸场地的粉砂层中也发现了无定形片状物。我们可以在不同的生态环境下获得史前人类群体之间交换和社会关系的基本数据。关于狩猎采集者和农民之间相互依存关系的变化历史的民族考古学研究将在下一个田野季节举行。(7)综合生存活动模式和文物年代学，得出3，000 BP至1，000 BP的遗址分布模式。(8)在报告撰写期间，菲律宾和日本考古学家为了解这些考古特征积极进行了思想交流。最后对今后的研究设计进行了展望。少

(1) The excavations of river bank shell middens have been continued to acquire the artifacts to build up the local chronology. By the result, the chronological sequence is subdivided into four periods, such as Red-slipped pottery I chronology. By the result, the chronological sequence is subdivided into four periods, such as Red-slipped pottery I*Red-slipped pottery II*Black pottery I*Black pottery II.And st is clarified that the chronological sequence correlate to the changing patterns of settlement.(2) The scientificanalyzes of C14 datings, identification of faunal and floral remains, seasonal and habitat identifications of faunal and floral remains, geological and pollen samples have been performed continuously. By the results of analyzes, we could get the key to understand the prehistoric changing patterns of environmental exploitation and subsistence strategy, that is the formation of shell middens was begun by the environmental change from the swampy to fluvial condition of Cagay … More an River. And latter, numbers of shell midden increased in the lower river.(3) In the two river bank sites, the human skeletal remains are revealed from the silt layr under the shell midden. The isotope analysis for the prehistoric diet and the physical anthropological analysis are on going at this moment at the National Museum of the Philippines.(4) By the result of isotope analysis, it is clarified unexpectedly that the prehistoric Lal-lo shell gatherers' diet was dependent on the terrestrial mammals.(5) The geological and pollen study team performed the boring at the river bank and inland sites, and the data on the gelolgical settings of each site and the pollen samples are acquired.(6) By the excavation of cave site located on the hilly area, the amorphous flakes and Red-slipped pottery sherds are collected. The amorphous flakes are also revealed from the silt layr of river bank site. We could have the basic data on the prehistoricexchange and social relationships between human groups based on the different ecological settings. The ethnoarchaeological research on the changing history of interdependent relationships between hunter-gatherers and farmers will be held at the next field season.(7) Synthesizing the patterns of subsistence activities and the chronology of artifacts, the site distribution patterns from 3,000BP to 1,000BP.(8) The exchange of ideas among Filipino and Japanese archaeologist for the understanding of these archaeological traits are carried out actively during the report wreiting. The future research design is also discussed. Less
