I. Introduction In 1958, I did geological surveys at the foot of the Dabie Mountains at the junction of Henan and Anhui provinces. Some experience in the actual work, would like to do a brief introduction here, provide a reference. Few people liberated before the liberation of the region conducted a systematic geological survey, so the information is sporadic. In 1924, Tan Xichou et al.
