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
Several dust accumulation sections have been found in the Xuancheng area of Anhui Province. Their common feature is the widespread deposition of Paleolithic stone products. The section of Xiangyang-Chenshan section (30 ° 52’32 “N, 118 ° 51’58” E) is formed on the back of a hillock facing the Shuiyang River with a cross-section of about 10 m, which is about 817 ka BP. The results of particle size analysis and magnetic susceptibility measurements of continuous sampling in the whole section show that in addition to the sediment-paleosol layer at the bottom of the section, there are also 8 cycles of “aeolian deposition-paleosol layer”, depositional environments of dust deposition and northern loess Sedimentary environment is similar. From the bottom of the profile to the near top, scattered Paleolithic stone products were relatively simple and slow to progress, with sharp cutters as the characteristics, and the Qinling - Huaihe River north of the Paleolithic stone product combinations have obvious differences
