| Abstract: | Bauxite deposits in southern Yanshi occurs in Benxi group of Carboniferous system on the long term weathering erosion surface of Middle Ordovician and distributed on the transition belt of Songshan upwelling and Qinyang-Kaifeng subsiding of Earlier Paleozoic Era,The tectonic environment is relatively stable and sedimentary interruption period is long.The sedimentary facies is littoral-lagoon facies.Weathering and leaching plays critical role and improving grade of ore in late period. |

| Keywords: | bauxite deposits Benxi group tectonic environment sedimentary facies weathering southern Yanshi Henan province |
