The mineral is a key to understand the earth and extraterrestrial objects for human beings.With the rapid development of modern in situ analysis techniques,a large amount of mineral geochemical data has been accumulated in an exponential growth mode.However,the complex structures and various types and formats of these data hindered the reuse of mineral big data and related comparative researches.In view of the advantages of mineral geochemical data in solving various questions of geosciences,as well as their complex data structure and exponential growth trend,a mineral geochemical data information system(MinerGeochem,http://www.minergeochem.com/)was developed based on the computer information technology,web application,relational database,and GIS.The system consists of information hardware infrastructure,operating system/database system,service components,and application modules.The functional modules include the user management module,website content module,data management module,record management module,system configuration module,GIS data visualization,and data import and export module.The data dimension consists of four types of data structures including the mineral deposit data,mineral data,experiment data,and literature data.Each type of data contains multiple attributes,and these data are related through their attributes for enabling the search and acquisition of any data attribute.Data standardization and data upload are simply and fast processed in batches using Excel templates.The MinerGeochem which has a simple interface is easily used.The system will be important part of the geoscience database and will provide data support for geoscience researchers.
