The spatial database of 1∶2 500 000 geologic map of the intrusions in North China (also referred to as the Database) was established based on the data obtained from 1∶250 000- and 1∶50 000-scale basic geological surveys and special studies of North China conducted in recent years, as well as the latest literatures from China and abroad. Focusing on the intrusions in North China (also referred to as the study area), a geologic map was prepared and a database was built to express the spatial-temporal framework, material composition and spatial belt division of the intrusions in North China. The map was prepared with the MapGIS 6.7 software. The intrusions in the map were denoted by means of ‘lithology + era’. The map, with a data size of about 218 MB, covers 1743 graphic primitives of intrusions, 1534 stratigraphic units and 404 pieces of isotopic age data. Meanwhile, corresponding attributes were assigned to the graphic primitives of the intrusions and the isotopic ages. The geological map highlights the division of magmatic rock belts in North China, with the data of different magmatic rock belts being collated in detail including spatial distribution, magma stages, rock association, geochemical characteristics, genesis and tectonic background. This Database fully reflects the new achievements obtained from geological survey and scientific research in recent years. Therefore, it will provide basic geological maps and data for future geological surveys, scientific research and production. In the meantime, to a certain extent, it can be used as a reference for resource exploration and economic and social development.
