Based on the analysis, contrast and conclusion of its secondary enrichment zones,the changing regulation of depth,thickness and grade of the secondary enrichment zones in the Leimengou gold deposit were brought to light,and the forming mechanism of secondary enrichment zones was further expounded in theory.
本文从三条典型含金蚀变破碎带入手 ,通过对其次生富集带的分析、对比、归纳 ,揭示出次生富集带的深度、厚度和品位变化规律 ,并进一步从理论上阐明次生富集带的形成机理。
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。
