“LOESS” IN XUANCHENG PREFECTURE OF ANHUI PROVINCE AND PALAEOLITHIC CULTURE
-
摘要: 安徽省宣城地区发现几处风尘堆积剖面,它们的共同特征是普遍埋藏着旧石器时代的石制品。向阳陈山剖面(30°52'32″N,118°51'58″E)背依群岗,面向水阳江,剖面高约10m,大约是817kaBP以来形成的。全剖面连续采样的粒度分析与磁化率测量成果表明,该剖面除底部河漫滩相沉积-古土壤层外,还有8个"风尘堆积-古土壤层"旋回,风尘堆积的沉积环境与北方黄土的沉积环境相近。从剖面底部到近顶部,分散出土的旧石器时代石制品制作比较简单,进步缓慢,以尖状砍砸器为特色,与秦岭-淮河一线以北的旧石器时代石制品组合特征有明显的差别。Abstract: In the Xuancheng prefecture of Anhui province,there are quite a few profiles composed of aeolian-dust accumulation,in which were buried palaeolithic stonewares.The profile located at Chenshan hill(30°52'32″N,118°51'58″E),Xuancheng prefecture,was accumulated since 81.7×104aBP,and 8 cycles of wind dust accumulation-palaeosol development are found by an analysis of the susceptibility and grain size of samples continuously collected in the profile.The depositional environment of the aeolian-dust accumulation is similar to that of the loess accumulation in northern China.The palaeolithic stoneware from Chenshan profile as was shaped by simple chopper belongs to the southern culture system in the palaeolithic age,which was diferent from that north of the Qinling Mountain-system-Huaihe River in the stoneware assemblage.
