Yang Huai-jen, Yu Su-ch黱 and Han Tung-chun
The region under consideration lies west of the Lu-liang Shan and east of the gorge of the Yellow River (Fig. 17). As a result of much intensive work done duung the past thirty years by Andersson, Barbour, Bien, Licent, Pei, Teilhairl de Chardin, Yang and others, the stratigraphy of the Late Cenozoic Yeuud in this mgion seems to be reasonably well established. In consideration of the erosional and depositional history of Shansi and its neighbouring provinces of North China, different "Stages" have been proposed.
