豫西铝土矿聚集区的成矿条件与富集规律探讨

The metallogenic condition of bauxite and enrichment patterns in western Henan

本文通过对豫西铝土矿聚集区与富集规律的研究,综合该区成矿构造条件、物质来源、沉积环境、古地理及古气候以及富集规律特征,提出了三门峡——新安成矿亚区和嵩、箕成矿亚区应是找矿的重点地区;在大面积浅覆盖的准平原区的湖盆边缘地带,应结合物探和煤田地质资料,有效地指导中、深部的普查找矿工作;并要重视中奥陶统灰岩岩溶洼斗发育区的普查评价工作。

Based on the study of metallogenic condition of bauxite and enrichment patterns characteristic,tectonic conditions,source materials,sedimentary environment,paleogeography,paleoclimate in western Henan.According to the information,we can draw a conclusion that the frist,the sub-region of the Sanmenxia-Xin’an mineralization and the Song,Kei metallogenic area should be the key areas of prospecting.The second,the Lacustrine basin margin areas of the peneplain district of a large area of shallow cover,we should bu combined with gelphysical and coal geological data to guide the census prospecting work in the deep.The last one,we should pay attention census evaluation of the linestone karst of development areas.
