摘　　要：支建铝土矿位于三门峡—新安铝土矿成矿带。通过对支建铝土矿的结构要素及成因、构造特征、沉积层序、主要组分变化与埋深、沉积环境、迁移和沉积方式的研究,初步建立了该区铝土矿的沉积模式,指出进一步的找矿方向,即在古陆周围深部煤系地层之下,仍能形成具工业意义的铝土矿体,这对河南省铝土矿找矿工作和煤矿的资源转型有一定的借鉴意义。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.
