This article attempts to extract characteristics of the weathering pits by descriptive statistics and orientation rose diagrams, investigate the multi-phase evolution by the modified gnamma morphological analysis （GMA） method, and shed new light on the possible genesis and the influencing factors. Following the modified GMA method, weathering pits in Qing Mountain have been divided into six groups and compared with analogous sites to deduce their approximate age, which might be no older than 30 ka B.P., and explore the possibility that the multi-phase evolution of weathering pits may arise from responses to climate change. In consequence, we suggest that the combination of weathering, especially salt weathering, and wind erosion, both of which are closely related to climatic variation, take the main responsibility for the formation and development of weathering pits in Qing Mountain.展开更多

The eight tombs excavated are all rectangular earth pits, small in size and varying in direction. They are with or without coffins, and contain burials mostly in an extended supine position. A few human skeletons were found with bronze arrowheads inserted in them, and sheep bones were discovered as the remains of animal victims. The funeral objects are relatively small in number, with the pottery vessels belonging to the jar, pot, bowl, etc., all grey clay ware fired at a rather high temperature, and the bronzes including belt hooks, arrowheads and rings. These show quite typical features of the Central Plains culture. The tombs can be assigned to the Warring States period according to their shape and the characteristics of their objects.展开更多
