西秦岭东段徽县、成县南部的下石炭统,在前人资料中多认为只存在维宪阶,而缺失杜内阶。1974年我队在徽县南部开展铝矿普查,测制剖面,分别于严家坪南侧和高崖南侧等地发现杜内期化石。今将所获新资料作一报导。徽县嘉陵公社严家坪剖面(图1)。

In the eastern part of the western Qinling Hui County, the lower Carboniferous in the south of Cheng County, many of the data in the predecessors think there is only Victoria constitutional order, and the absence of Duneti hierarchy. In 1974, our team carried out the census of aluminum mine in the southern Huixian County to test the profiles and found the Dunesian fossils in the south of Yanjiaping and the south of Gaoya respectively. We will make a report on the new material we have obtained. Emblem Jialing commune Yanjiaping section (Figure 1).
