Abstract: The 1:50 000 mineral geological map of the Huaniushan map-sheet (K46E017023), Gansu province, is developed in accordance with the Technical Specification for Mineral Geological Survey (1:50 000) and unified standards and requirements in the sector, building on making full use of results from and information of 1:200 000 and 1:50 000, etc. regional geological survey, applying the digital mapping system to plot geology-specific maps in the field and adopting the method integrating indoor and outdoor mapping and compilation. In this map, the formation type of the Nanhua-system-Sinian-system Xichangjing Group, Cambrian-system Xishuangyinshan Formation and Ordovician-system Huaniushan Group is reclassified, the periods of intrusive rocks in the map sheet are included in three periods, i.e. late Ordovician epoch-early Silurian epoch, Devonian period and late Triassic epoch, and the evolutionary sequence of magmatite. The database contains data and information of 12 stratigraphic units and magmatite of three periods, with a data size about 3.77 MB. These data fully reflect demonstrative results from the 1:50 000 mineral geological survey, provide a reference to mineral resource research and energy exploration in the area.
