|Abstract:Geological profile map is an important physical geological data. According to the geological profile, we can get information about lithological characteristic, structural feature, stratigraphic assemblage, contact relationship and so on. The description of geological profiles includes information such as specimen, thin section, measured section, stratified description of measured section, etc. Understanding the description of geological profiles can not only help field geologists to carry out their work more effectively, but also provide more complete basic data for subsequent research. Therefore, it is of great significance to the description of geological section maps. Based on the author's own practical work, the author expounds the problems found in the description of geological section maps, and put forward his own suggestions on how to solve these problems.
