宁夏海原县南华山旧石器考古调查

2020年4-6月,宁夏文物考古研究所与海原县文管所组队对海原县南华山地区进行史前时期遗存专项考古调查。此次调查共发现旧石器地点27处,其中明确地层的有14处。从地层上看可大致分为18000 BP以后的马兰黄土堆积和24000-18000 BP马兰黄土下部河漫滩相堆积两期,分别以石叶-细石叶工业和小石片石器工业为代表。油坊院遗址第1地点和刘湾遗址断面上发现较厚的灰烬堆积,前者还发现有1处明显的火塘遗迹;测年数据显示,两者年代分别为22000 BP cal和11000 BP cal。此次海原县南华山地区旧石器的发现,为研究中国西北地区旧石器晚期文化提供了新的材料,为进一步探讨LGM阶段中国北方旧石器晚期的环境、文化与人群交流等问题提供了新的线索。

Paleolithic archaeological investigation in Nanhua mountain area of Haiyuan,Ningxia

From April to June 2020, the Ningxia Institute of Cultural Relics and Archaeology cooperated with the Haiyuan County Cultural Management Office to conduct a special archaeological survey of the prehistoric remains around the Nanhua mountain. A total of 14 Paleolithic sites with clear strata were found in this survey, which can be roughly divided into two different accumulative phases, the Malan loess about 18 kaBP and the floodplain deposits about 24~18 kaBP. Among them, ash heaps were found on the sections of the YouFangyuan 1st and LiuWan sites. The dating data show that the YouFangyuan 1st is about 22 kaBP cal, and the LiuWan sites is about 11 kaBP cal. The discovery of the Paleolithics in the survey provides new data for the study of the late Paleolithic culture in Northwest China, and provides new clues for further discussion of the environment, culture, and communication of human groups in the late Paleolithic in northern China during the LGM stage.
