Abstract:
      BACKGROUND: A geological database is an important part of earth information science, which will provide reliable data support for geological research and application. Re-Os dating technology is widely applied in the study of ore deposit, mantle evolution, and marine environment.
OBJECTIVES: To construct a journal publication-based Re-Os dating database to integrate related research achievements, and improve the management and application of the technology.
METHODS: The technical route of GIS spatial database construction was adopted, and systematically studied database construction methods from multiple dimensions such as database construction ideas, data integration methods, and data database construction.
RESULTS: The database used publicly published Re-Os isotope dating documents as the data source and gathered more than 100 publicly published Re-Os dating documents from the last ten years. More than 35 journals were involved. The data sources were authoritative, extensive and representative. Through the structural transformation and spatial processing of unstructured fragmented document data, the database had the characteristics of authoritative data source, structured data content, and attributed spatial location.
CONCLUSIONS: The Re-Os dating database has a reliable data source, which can provide data support for the geological survey and research of mineral deposits.
