Excavations on the Lal-lo Shell Middens, Northern Luzon, Philippines - Archaeological Studies on the Hunter-Gatherer/Farmer Interdependent Relationships

1.建立了Lal-lo贝壳米登四个陶器组合的类型年代学。出土墙壁的地层学以及与不同陶器组合相关的每一层样品的AMS 14C年龄证实了时间顺序。七个阶段的时间顺序如下：1 .剥片组合（7000-4000calBP）→红溜陶组合（4000-3700calBP）→无装饰红溜陶组合（3400-3000calBP）、有装饰红溜陶组合（2900-2400calBP）→有装饰黑陶组合（2300-1500calBP）→无装饰黑陶组合（1500-1000calBP）→贸易器皿（600-500calBP）通过对卡加延河东岸石灰岩丘陵地区的发掘，证实了片状陶器和装饰红滑陶器的关联。这些事实似乎支持史前狩猎采集者和农民相互依赖的模型。通过挖掘和钻孔确认了卡塔扬贝壳米登的规模。尺寸为长两公里，宽100米，深两米。时间深度从前铁器时代延伸到铁器时代。在Dummon Shell middens的Gaerlan遗址证实了从薄片组合到陶器组合的过渡。建立了碳定年的新方法。这种方法使用从黑陶碎片的浆糊中提取的碳。为了重建卡加延河下游的古环境，地质小组在洪水面开始钻孔。利用地理信息系统（GIS）建立出土文物和遗址的数据库。动物园的考古学家已经收集并制作了现在的鱼骨标本。综合这些从遗址中发现的数据，首席调查员构建了该地区史前狩猎采集者和农民之间社会互动的考古模型，并发表了这一模型。少

1.Typological Chronology of the four pottery assemblages from the Lal-lo Shell Midden was established. The Chronological order was confirmed by the stratigraphies of excavated walls and also the AMS 14C ages of the samples from each layers associated with different pottery assemblages. The chronological order of seven stages is as follows ; the Flake Assemblage (7000-4000calBP)→the Red-Slipped Potteries (4000-3700calBP) → the Non Decorated Red-Slipped Pottery Assemblage (3400-3000calBP), the Decorated Red-Slipped Pottery Assemblage (2900-2400calBP)→the Decorated Black Pottery Assemblage (2300-1500calBP)→the Non Decorated Black Pottery Assemblage (1500-1000calBP)→ the Trade Wares (600-500calBP).2.By the excavations of limestone hilly area, on the eastern bank of the Cagayan River, the associations of the Flake Assemblage and the Decorated Red-Slipped Pottery Assemblage were confirmed. These facts seem to support the model of prehistoric interdependency of hunter-gatherers and farmers.3. … More The dimension of Catayauan Shell Midden was confirmed by the excavations and borings. The dimension is the length of two kilometers, the width of 100 meters and the depth of two meters. The time depth extends from the Pre-Iron Age to the Iron Age. The transition from the Flake Assemblage to the pottery assemblage was confirmed in the Gaerlan site of Dummon Shell Middens.4.The new method of carbon dating was established. This method uses the carbon extracted from the paste of the Black Pottery sherds. For the reconstruction of palaeoenvironment of the Lower Cagayan River, the geologist group started the borings in the flood plane. The GIS (Geographical Information System) has been used for the data base of excavated artifacts and sites. The zoo archeologists have collected and made the present fish bone references.5.Integrated these data revealed from the sites, the head investigator had constructed the archaeological model of social interactions between prehistoric hunter-gatherer and farmer in this area, and published.
