赣南于都金银多金属矿整装勘查区1∶50 000银坑幅矿产地质图数据集

In order to develop this dataset, data were acquired comprehensively by using multiple methods such as mapping which is specific for lithology, structures and mineralized alterations, remote-sensing, geophysical/geochemical and drilling exploration. A route of 520.65 km was surveyed, with 2 047 stream sediment samples and 167 chemical analytical samples collected, and 461 km2 area interpreted based on remote-sensing data. Emphasis was placed on survey and division of early-Yanshanian metallogenic magmatite, ore-bearing formations, rock-control and ore-control structures, and mineralized alteration marks etc., so that it could be verified that the main metallogenic geological bodies for Au-Ag multi-metal ores within the area were early-Yanshanian granodiorite and that the rock-control and ore-control formations were a NE-strike thrust faultand its secondary fissures. Building on this, the 1∶ 50 000 formation and tectoni map of the Yinkeng Map-sheet was compiled, the mineral geological map dataset was established by using a digital mapping system (DGSS), a map layer property database on key formations & tectonics, geological boundaries, fractures and magmatite etc. was comprehensively compiled; the prospecting prediction model for Yinkeng-style mid-low temperature post-magmatic hydrothermal deposits in the area was improved, highlighting the causal relationship between deposits and the formations or structures in the area.
