Abstract: On the basis of the detailed study of the main host strata (Huanglong Formation) and their sedimentary facies and palaeogeography in the Jiurui region, Jiangxi, the present paper discusses the principal features of combined ore control of strata, sedimentary facies and tectonic settings in the Huanglong Formation, and demonstrates that the important controls of the formation and distribution of the stratabound deposits in the study area include the Upper Carboniferous Huanglong Formation and its sedimentary pyrite horizons, Weiningian (Late Carboniferous) sedimentary facies and palaeogeographic environments and NWW-trending tectonic settings.
