Bauxite ore in Songqi area,Henan province is characterized by secondary enrichment.
河南省嵩箕地区铝土矿具有明显的次生富集规律:次生富集最强的部位在潜水面附近,通常为矿体埋深40~70 m的部位;深度大于130 m的含矿地段氧化程度变低、矿石质量下降;矿石氧化富集的内因为Al2O3和SiO2的地球化学差异,外因是矿体内地下水的补给量及其排泄能力的强弱,铝土矿在次生氧化作用中不断地脱硅富铝,形成富铝土矿石;适宜的构造和地貌条件是地下水补给、排泄的有利保证,上石炭统底部靠近铝土矿层的岩溶溶洞是向矿层内补充大气降水的主要通道。
