中文摘要	近年来，在东秦岭南洛河流域发现了大批旧石器地点，该区域被认为是中国南北方旧石器工业的交汇和过渡地带。但是，早期人类在这一带的活动时间和环境背景尚不清楚。由于第四纪黄土的定年方法相对成熟，旧石器遗址的黄土堆积可为解决这些问题提供重要证据。对洛南盆地上白川和刘湾两个遗址的黄土剖面进行土壤地层和磁性地层研究以及光释光年龄和磁化率测定结果显示，该地区的黄土堆积可能从110万年前就已经开始，地层有明显的黄土-古土壤旋回，指示了气候和环境在冰期-间冰期时间尺度的变化。黄土地层下部出土的石制品表明，至少在约80万年前后人类就在这一带活动并制作工具。石制品两面加工技术被广泛采用，大量制作精美的手斧和薄刃斧等Acheulian工业类型工具的发现，显示洛南盆地的旧石器工业可能已经突破了莫氏线(Movius Line)的框架。
英文摘要	A large number of lithic artifacts of Pleistocene age have been collected from the Luonan Basin, located in the Eastern Qinling Mountains ( Central China) over the past ten years. This area is regarded as one of the most important places for understanding hominid behavior in the recent geological time. However, the lack of suitable dating material and sedimentary records has restricted our investigation of human evolution, behavior, and environmental changes. The Luonan Basin and the South Luohe River catchment contain typical loess sequences, in which lithic artifacts are buried. These deposits can be well dated and used as a proxy record of past environmental change. The loess sequence provides a secure time-scale for dating the associated artifacts, and they also provide a basis for climatic and environmental reconstruction as a background to past human settlement. In this study two loess sections, one located in Shangbaichuan with a thickness of 24. 8 meters, and the other in Liuwan with a thickness of 13 meters, have been investigated by an interdisciplinary research team. Our results show that these loess deposits are aeolian in origin with strong weathering process. The loess-paleosol alternations are related with the glacial-interglacial changes of the Northern Hemisphere environment during the Pleistocene. Analyses of the stratigraphy and depositional processes, plus optically stimulated luminescence dating, palaeomagnetic stratigraphic analyses, as well as magnetic susceptibility measurements show that the loess deposit in this region started accumulating at least 1. 10 million years ago. There are clear warm/cold and humid/arid alternating phases indicated by loess and paleosol sequences in the Eastern Qinling Mountains during this time. The discovery of lithic artifacts in the lower parts of the loess indicate that early hominids were living in this region at least 0. 8 million years ago. The hand-axes and cleavers found in this region indicate that Mode 2 Acheulian tools were distributed beyond the "Movius line" in Eastern Asia. However, more survey and systematic excavation is needed to further understand human evolution, technological behaviors, and environmental changes in this important geographic transition zone in Central China.
