The 1:50 000 MineralGeological Map Dataset of the Yinkeng Map-sheet, Yudu Au-Ag Multi-metal Ore Integrated Area, South Jiangxi

Abstract
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 fault and its secondary fissures. Building on this, the 1: 50 000 formation and tectonic 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.
