太行山北段早前寒武系龙华河群为六十年代所建,后来发现五台山区的五台群底界已延入龙华河群之中。近年来,许多新资料表明,它实际上包括了龙泉关群、五台群及滹沱群的一部分。因而,应废除龙华河群,并对它进行重新划分。 The northern part of the Taihang Mountains Longhuahe early Precambrian group was built in the sixties, and later found that the Wutai Mountain in Wutai Group has been extended to the bottom boundary among the group. In recent years, many new sources have shown that it actually includes part of Longquan Guanqun, Wutai Group and Hutuoqun. Therefore, Longhua River Group should be abolished, and it should be re-divided.
