摘要:

泥河湾古湖发育末期古人类遗址的保存与埋藏特点尚有待揭示。本文对新近发现与发掘的蔚县暖泉北官堡B地点的遗址埋藏过程进行分析,地貌和沉积物特点表明,该地点埋藏于壶流河北岸的暖泉湖积台地内,文化遗存在泥河湾古湖消亡前的粉砂层内。光释光年代测定表明古人类在该遗址活动的时间大致在距今21万年前,处于中更新世晚期。遗物埋藏学(石制品磨圆程度、尺寸分布和技术组合)、空间分析(核密度估计)和组构分析(标本走向与特征向量)显示,中等强度的湖滨片流参与了北官堡遗址B地点的埋藏过程,对古人类技术组合的整体完整性造成了扰动。本研究表明,受气候等因素影响,泥河湾古湖发育后期规模萎缩,湖滨地带多受到地表径流的改造,古人类选择相对稳定的湖滨地貌景观活动,湖滨片流参与遗址后续的形成过程。对北官堡遗址B地点的进一步研究,有助于正确解读古人类的遗址利用方式与生存策略,同时对完善泥河湾盆地古人类对湖泊发育末期地貌景观的利用策略具有重要意义。

Abstract:

The relationship between the evolution of the Nihewan paleolake and early human activities has long been a focal issue in Paleolithic research. However, the preservation conditions and site formation processes of Paleolithic sites formed during the terminal stage of the lake development remain insufficiently understood. This study focuses on the newly discovered and excavated Paleolithic site of Beiguanbu Loc. B (BGB-B) and aims to decipher its taphonimic history. The BGB-B site is located in the Nuanquan Platform of Yuxian County, Hebei Province. The archaeological remains are preserved within silt deposits that were formed prior to the final extinction of the Nihewan paleolake. Geomorphorlogical and sedimentological evidence indicates that the BGB-B site is embedded within a fluvio-lacustrine sequence on the northern bank of the Huliu River. Optically stimulated luminescence (OSL) dating suggests that hominins occupation of the site at approximately 210 ka, placing it in the late Middle Pleistocene.

Various taphonomic indicators of remains (including edge abrasion, size distribution, and technological composition), together with kernel density surfaces of lithic remains and fabric analysis based on artifact orientations and eigenvectors, indicate that moderate-intensity hydraulic lakeshore sheetwash from northeast direction contributed to the formation processes of the BGB-B and reduced the overall integrity of the lithic technological record. The results suggest that during the late stage of Nihewan paleolake development, climatic fluctuations contributed to lake shrinkage, and lakeshore environments were increasingly modified by surface runoff. Early humans preferentially occupied relatively stable lakeshore landforms, and low-energy sheetwash processes played a role in the formation of the BGB-B assemblage. Further investigation of the site will provide important insights into the interpretation of human occupation behavior and subsistence strategies. As a result, it also can contribute to a better understanding of how hominins utilized lakeshore landscape during the terminal phase of paleolake evolution in the Nihewan Basin.
