豫中地区隐伏铝土矿资源潜力预测

豫中地区是河南省铝土矿的主要产区,通过总结该区铝土矿的成矿规律、分布特征、找矿标志及已有铝土矿及煤矿的勘查资料,系统地编制石炭系上统本溪组铝土矿含矿岩系的底板埋深等深线图,对不同埋深的隐伏铝土矿资源量进行了定量预测,划分了预测区类型。指出该区隐伏铝土矿潜在资源量112142.90万吨,尚有未探明资源量76641.48万吨。

Prediction of concealed bauxite resource potential in the central part of Henan province

The central part of Henan province is the main production area of bauxite in the province.After summarizing the metallogenic regularity,distribution characteristics,clues for prospecting of bauxite in this area and acquired exploration data of bauxite and coal mine,this paper systematically draws up contour line map of baseplates＇ buried depths of bauxite ore-bearing rock series of Benxi formation of upper Carboniferous.The paper makes quantitative prediction on concealed bauxite resource on different depths,and divides the predicted areas into different types of groups.The author believes that the potential resources of concealed bauxite in this area are 1121429000 tons and the unexplored resources are 766414800 tons.
