自1958年对遵义含铝岩系进行工作以来,直到七十年代末期,其地质时代各家均置于早二叠世早期。根据生物化石带的对比研究,杨绳武等还提出:鉴于汉中梁山地区或黔北地区的栖霞组底部未发现Wentzellophyllum volzi,因而“有可能其梁山组大部相当于黔南区栖霞组底部Wentzellophyllum volzi带”,即黔南的“梁山组”可能在这些地区大部缺失。至七十年代末—八十年代初,随着1:20万息烽幅区调工作的开展,通过多种手段对黔中南,北含铝岩系的详细对比和研究,朱霭林等首次对息烽、开阳、遵义的铝土矿及其含
Since the work on the Zunyi aluminous series in 1958, until the late 1970s, each of its geological age was placed in the Early Permian. According to the comparative study of the biological fossils, Yang et al. Also proposed that in view of the fact that wentzellophyllum volzi was not found at the bottom of the Qixia Formation in Liangzhan area or Qianbei area in Hanzhong, “it is probable that most of its Liangshan formation is equivalent to the Wentzellophyllum volzi belt at the bottom of the Qixia Formation in southern Qiannan ”, That is, Qiannan’s“ Liangshan Formation ”may be largely missing in these areas. From the late seventies to the early eighties, with the 1: 200,000 regional adjustment work carried out, detailed comparison and research on the mid-south and north aluminous rock series by means of various means, Zhu et al. On Xifeng, Kaiyang, Zunyi bauxite and its containing
