Quaternary borehole database for 1∶50 000 Shaliu River Map-sheet of Hebei Province, China

The 1∶50 000 Shaliu River Map-sheet of Hebei Province is one of the key map-sheets for geological surveys of Beijing-Tianjin-Hebei plain Region, and the Late Cenozoic in the mapping area was mainly surveyed, with Quaternary borehole database reflecting the core achievement of the geological survey. By taking advantage of borehole construction and test data, as well as combining the collected borehole data, Quaternary borehole database was thus built, which mainly includes one basic data layers for borehole, five borehole catalog databases, five borehole design databases and five borehole histograms. Data source, data processing method, data attribute structure and data quality control are summarized in this paper, so as to present the practice of Quaternary borehole databases on the basis of Digital Geological Survey System (DGSS). The database provides a 3D geologic model of Tangshan urban area with basic data, serving coordinated development of Beijing-Tianjin-Hebei Region, which could also be referenced by borehole data processing and database construction in the geological survey of the other plain areas.
