在人类进化研究中，世界不同地区最早的居住和最古老的石器技术的时间仍然是一个有争议的话题。在这里，我们提供了中国北部泥河湾盆地小长梁两个暴露在外的平行湖相剖面的详细磁性地层学结果；这些结果对20多年前最初报道的旧石器时代石器的年龄进行了严格的控制。我们的古地磁发现表明，人造物层位于以Olduvai和Jaramillo亚时区为边界的反向磁臭氧中。再加上估计的沉积速度，这些发现将该层的年龄限制在大约136万年前。这一结果代表了东亚已知的最古老的石器组合的年龄，其中包括可识别的旧石器类型，以及该地区最早的明确占领，最北可达40° N。
The timing of the earliest habitation and oldest stone technologies in different regions of the world remains a contentious topic in the study of human evolution,,,. Here we contribute to this debate with detailed magnetostratigraphic results on two exposed parallel sections of lacustrine sediments at Xiaochangliang in the Nihewan Basin, north China; these results place stringent controls on the age of Palaeolithic stone artifacts that were originally reported over two decades ago. Our palaeomagnetic findings indicate that the artifact layer resides in a reverse polarity magnetozone bounded by the Olduvai and Jaramillo subchrons. Coupled with an estimated rate of sedimentation, these findings constrain the layer's age to roughly 1.36 million years ago. This result represents the age of the oldest known stone assemblage comprising recognizable types of Palaeolithic tool in east Asia, and the earliest definite occupation in this region as far north as 40° N.
