摘　　要：以道真县大塘铝土矿7号主矿体为例,总结上石炭统黄龙组(C2h)与下二叠统大竹园组(P1d)地质特征。通过对黄龙组灰岩厚度与大竹园组含铝岩系厚度、矿体厚度、矿体品位、矿体铝硅比值特征进行对比分析,认为该区铝土矿矿体、含铝岩系的厚度、矿体品位与黄龙组灰岩厚度有一定的负向变化关系;矿体品位与含铝岩系厚度和矿体厚度有一定的正向变化关系;矿体铝硅比值与黄龙组灰岩厚度有一定的负相变化关系,与矿体品位有一定的正向变化关系。Taking the No.7 main orebody of Datang Bauxite in Daozhen County as an example,the geological characteristics of the Upper Carboniferous Huanglong Formation(C2h)and Lower Permian Dazhuyuan Formation(P1d)are summarized.Through the comparative analysis of the thickness of the limestone of the Huanglong Formation and the aluminous rock series of the Dazhuyuan Formation,the thickness of the ore body,the grade of the ore body,and the characteristics of the aluminum-silicon ratio of the ore body.It is believed that the thickness and grade of bauxite ore bodies and aluminous rock series in this area have a certain negative relationship with the thickness of the limestone of the Huanglong Formation.The grade of the ore body has a certain positive relationship with the thickness of the aluminous rock series and the thickness of the ore body.The ratio of aluminum to silicon of the ore body has a certain negative relationship with the thickness of the limestone of the Huanglong Formation,and a certain positive relationship with the grade of the ore body.
