This database contains boundaries of areas in which geochemical samples were collected for analysis. The boundaries are grouped according to geographical location and survey objectives. Individual boundaries refer to areas of specific geochemical surveys and are supplemented with information on geochemical projects, locations, types of exploration, sampling grid geometry, the number samples collected, and location of sample storage, and archival numbers of CGS-Geofond assessments that provide links to data from the ASGI Database and identify samples. This allows each sample to be linked to a detailed description and to the chemical parameters stored in the Geochemical Measurements Database.
Zdrojem informací jsou zejména zprávy archivované v České geologické službě a v družstvu Geomin Jihlava (nástupce Střediska užité geochemie Geoindustrie Jihlava). Databáze vznikla v roce 1989.
