摘要
2021年7月和2023年10月,青海省文物考古研究院与四川大学考古文博学院联合开展了环青海湖区域的考古调查工作。调查队在海晏县达玉村甘子河流域新发现细石器地点9处,并发现了其埋藏的原生层位。通过小规模试掘,获得了一些文化遗存,包括石制品、动物骨骼碎片及磨制骨器。初步年代学研究结果显示,遗址的年代为距今9500年左右。本文是对此次调查和发掘结果的初步报告与研究,新发现的石器地点为讨论史前狩猎采集者对青藏高原东北部高海拔区域的利用提供了新材料。
The archaeological investigation was carried out jointly by the Institute of Cultural Relics of Qinghai Province and the School of Archaeology and Museology,Sichuan University,in July 2021 and October 2023.The new nine microblade sites were discovered along the Ganzi River in Dayu Village,Haiyan County,and the primary cultural layers containing microblade remains were excavated.Archaeological remains from a small-scale test excavation included lithic artifacts,animal bone fragments and ground bone tools.The AMS 14C dating indicates that the site dates back to around 9500 BP cal.This report presents the preliminary results from the investigation and the subsequent excavation,providing new evidence for the occupation of the Northeastern Qinghai-Tibetan Plateau by prehistoric hunter-gatherers at the beginning of the Early Holocene.Preliminary research indicates that the lithic technology is dominated by simple flake-core and microblade technologies.Quartzite and chert are the main raw materials.Quartzite containing cortex was found along the bank of the Ganzi River according to the investigations,while the source of chert remains unclear.In terms of the raw material use,chert is primarily used for microblade production,whereas quartzite predominates in flake-core complex.Techno-typological analysis reveals that the flakes were percussion mainly by single-platform cores,with a few double platform cores and core fragments were recovered.The platforms of flakes were mainly natural and plain,indicating a lack of preparation for the flake-core technology.Small size of conical and irregular microblade cores were recovered from the localities.Lithic analysis shows the platforms and flaking faces of microblade cores were frequently rejuvenated.The presence of tablet and over short flakes suggests the complete rejuvenation occurred on the microblade cores.The tools primarily consist of side scrapers,end scrapers and points.Unlike other sites in the Qinghai-Tibetan Plateau,we recovered bone fragments and ground bone tools.Specifically,the ground bone cones and spade were obtained from the test excavation which may indicate the intensive use of the animal bone resource.
