基于文献资源的Re-Os同位素定年数据库建设研究

地质数据库是地球信息科学的重要组成部分,可为地球科学研究工作提供可靠的数据基础。Re-Os同位素定年已广泛应用于矿床成因、地幔演化、海洋环境的研究中,建设Re-Os同位素定年数据库可整合相关研究成果,提升该领域成果资料的集成化管理和应用水平。本文采用GIS空间数据库构建的技术路线,从数据库建设思路、数据整合加工方法、数据建库等多个维度系统性地对数据库的建设方法进行了研究。数据库以公开发表的Re-Os同位素定年文献为数据源,汇聚了100多篇近十年来公开发表的Re-Os定年文献数据,涉及的期刊达35种以上,数据来源具有一定的权威性、广泛性和代表性。通过对非结构化碎片化文献数据的结构化转换、空间化处理,使数据库具备了数据来源权威、数据内容结构化、空间位置属性化等特点,可为矿床地质调查研究工作提供数据支持。

Study on the Construction of Journal Publication-based Re-Os Dating Database

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.
