Abstract: Abstract：The Zhijian bauxite ore district is located in the Shanmenxia-Xin’an bauxite ore belt. Based on a study of this ore district in such aspects as the textural elements and origin, structural features, sedimentary sequence, variation of the major components with the buried depth, sedimentary environment, transition and sedimentary mode, the authors have established a sedimentary model for this ore district and pointed out the orientation of further prospecting. It is thought that under the coal measure strata around the old landmass there still probably exist bauxite ore bodies of economic value, and the results obtained by the authors are of some reference value in further prospecting of bauxite ore deposits and resource transition of coal mines.
