The Provincial Geochemical Database and Information System PGD2.0 is a set of comprehensive applied system on the base of Chinease Windows 95 platform, by which data can be managed, processed and mapped . At present, the system has been spread and used. In the system, there are 4 databases: geochemical exploration database, sample analysis quality controlling database, medium large scale geochemical exploration database, and geological and geographical graphic database. It has a retrieving function of visual multi pattern conditions;a data processing function,by which the geochemical exploration data can be multivariable statistics analyzed and verified, projection transformed and system balanced; a mapping function, by which a contour diagram, or a colored contour diagram, or data position map, or a data symbol map and color block map all can be mapped; and a function of anomaly explanation. In Liaoning province, with the use of software the geochemical exploration database has been set up. After the establishment of the database, it is more convenient to use geochemical exploration data, and it is useful for anomaly sieving, exploration, and looking for target area of mineral deposits.
