DISCUSSION OF A NEW METHOD FOR THE ESTIMATION OF BAUXITE RESOURCES

The Yanlong large-scale bauxite deposit is newly found in western Henan Province by the integrated exploration. Based on the exploration, with study of the phase transformation of bauxite mineral and ore, this paper proposes a new idea about the orebody delineation and connection, i.e. the bauxite ore and co-existing minerals show gradual transition in both strike and dip directions. This knowledge results in a more scientific and reasonable estimating method for bauxite resources.
