摘要

    

The Yushan bauxite ore deposit in the western hemas-microsoft-com:office:smarttags" />Henan Province is a large concealed deposit discovered by Henan Institute of Geological Survey in 2005, which belongs to layer-G bauxite of North China Platform. The deposit-bearing strata of the Upper Carboniferous can be divided into two facies and further to four microfacies according to the systemic analysis of drilling data. The allite series of Yushan bauxite is formed in sedimentary environment of the shallow marine such as the coastal, the tidal flat or the lagoon, and the bauxite is mainly developed with the microfacies of oolitic (or classic) deposit that is formed in the upper part of restricted subtidal zone.hemas-microsoft-com:office:office" />
