Building of the mineral resource prospect investigation database in the digital geological survey system—Building and thoughts of the database of the Dalai Sum mineral prospect investigation project in Inner Mongolia, China

In accordance with the suggestion of the competent agency of China Geological Survey presented in May 2007, the authors selected the mineral resource prospect investigation project in the Dalai Sum area, Inner Mongolia, as a pilot project for the application of the mineral resource prospect investigation database system and carried out the building of the database in a complete way. According to the characteristics of the mineral resource investigation, the authors used the digital geological survey system to complete the following database buildings: (1) geological mapping field data PRB, (2) data and material database, (3) spatial database of geology and mineral resources, (4) geochemical database, (5) geophysical database, (6) remote sensing database, (7) integrated investigation result database, and (8) large-scale composite maps, thus realizing the digitalization of all the original mineral resource investigation data and investigation result data and integration of them into the digital geological survey system on a same platform.
