The 100-year development of the geological sciences reflects the meandering history of economic development and social progression in the 20th century, especially the dependence of industrialization on mineral resources and profoundly affection of social progression on the structural development of the geological sciences. The development and evolution paths of geoscience and its branch sciences in the point of computation view are derived in this paper, through the statistics and integration analyses of the international geological documents in the 20th century recorded in GeoRef database. The paths provide testimony of the point that the impetus of the development of geological sciences was changed from feeding to demanding, and record and reflect the affections of momentous historical events and mineral resource demanding during industrialization procedure on the development of geosciences. The paths also objectify that technological progression is the original revolutional impetus on the development of geosciences, and reveal that there is gap between geosciences in China and developed countries. It is a new method and idea to review quantitatively the long periodical developing principle of geosciences in the term of knowledge structure and the prosperity and declining of geological branch sciences through the application of statistics of the published scientific documents in 100 years.
