安徽省淮南、凤阳、定远一带,震旦亚界地层比较发育,早在1936年李四光教授就在这一带作过调查。其后,谢家荣(1945)、赵家骧(1949)也先后在这一带作过地质调查工作。解放后,徐嘉炜(1958)、杨志坚(1960)、朱兆玲(1964)又先后在上述地区作了比较详细的工作,初步建立了地层层序。近几年来,安徽省区测队在凤阳、定远一带进行区域地质调查时,又在前人工作的基础上,对地层系统作了部分修改和进一步
Anhui Huainan, Fengyang, Dingyuan area, Sinian strata relatively developed, as early as 1936 Professor Li Siguang in this area made a survey. Later, Xie Jialong (1945) and Zhao Jiaotong (1949) also successively conducted geological investigations in this area. After the liberation, Xu Jiawei (1958), Yang Zhijian (1960) and Zhu Zhaoling (1964) also made detailed work in the above areas successively, and initially established the stratigraphic sequence. In recent years, when the survey teams in Anhui Province carried out regional geological surveys in Fengyang and Dingyuan areas, on the basis of their predecessors’ work, they made some changes to the stratigraphic system and further
