Abstract: Geological cores and samples are of great economic and social value.The growing demand of geological cores and samples in the new situation requires that social service of them should be vigorously promoted.In this paper，by a follow-up study on the management and service of the geological cores and samples of different provinces (autonomous regions and municipalities) in China，the authors analyzed some problems such as the inconsistent technical standards，single collection and monitoring means，and impeded shared service.And then they put forward some suggestions on the development of the national geological cores and samples management and service for the next step，which are introducing a series of standards and regulations，working out collection planning，carrying out the clean-up of geological cores and samples，as well as further constructing the catalog database.
