I. Preface The Permian Bayinhe Group and the Connaught River Group in the area were created by Yang Zunyi equal to 1958 and named after Baying River and Norin River. At that time the establishment of the content is “Bayinhei mainly limestone sand quartz sandstone production: Schwagerina, Verbeekina, Polydiexodina, Echinoconchus, Dielasma, Pu-nctospirifer, Streptorhychus other fossils, 30.4 meters thick. Marlite, produced: Leptodus tenuis, Derbya magna, Buxtonia costato-concentrica and other Permian standard fossils, 42.7 meters thick. And that ”Bayinhe system generally comparable with the Yangsan South China, Connaught River and the Leping system compared."
