| 摘 要： | 从大地构造演化角度所作的成矿学分析表明:豫西铝土矿具有多因复成成矿的演化特征,地台阶段经红土化在地台构造层中形成的低品位三水铝石或铝质页岩,经过地洼阶段地洼期构造-热动力的叠加改造和地下水淋滤富化作用,最终成为具工业价值的改造富化型铝土矿。

METALLOGENIC CHARACTERISTICS OF THE BAUXITE IN WESTERN HENAN |

| Abstract: | Analysis from the tectonic point of view shows that the bauxite deposits have the evolution characteristics of poly-genetic compound ore deposit.Having been subjected to lateritization during platform stage, and tectonothermal dynamic superimposition and transformation and leaching_richening of underground water during diwa stage, low tenor gibbsite of Al_bearing clay eventually formed the transformation_richening type bauxite deposits. |
