摘要
用趋势面分析法恢复登封白坪G层铝土矿沉积时的古地形;用相关分析法研究了古地形对含铝岩系厚度、植物分布、钛率以及矿体分布、矿石质量、矿石结构的控制作用,提出了古隆起控矿的观点。在成矿机理与找矿方法方面也提出了新看法。
First, the writers restore the ancient topography in the span depositing G stratum bauxite at Baiping Dengfeng, Henan with the way of trend plain and prove it is reliable. Then, the writers investigate the function that ancient topography controles the thickness of aluminium—bearing system of rock, the distribution of plants, Al_2O_3/TiO_2 and the distribution of ore bodies, the quality of ore, the constructure of ore. The writers put forward the new view that ancient upheaval controles mineralization. The writers also have some new opinions in the process of mineralization and the way to look for mine.
