Abstract: Based on the project "pilot study on the geological information Clustering and industrialization" from the China Geological Survey,the article analyzed the constituent elements of nodes in the geological information clustering and the mechanism of geological information service,clarified the ideas of oriented user,data,and collaborative service.According to current situation of distributed collection,the tree node groups can play key roles in geological information service interface of fuzzy boundary,access initial shift,and Information flow orderly,and collection of nodes would be showing a strong development in the complex network in the industry and regional extension application as well as the geological information service transformation of traditional service mode.
