摘要
通过研究已探明的河南省陕县深部大型铝土矿——五门沟煤下铝(土矿)矿区的成功找矿实例,总结了五门沟煤下铝矿床的矿床地质特征、富集规律及找矿标志。其中关于煤下铝矿床赋存于上石炭统本溪组煤系底板与下伏中奥陶统灰岩的不整合之间,紫红色铁质黏土岩是煤下铝(土矿)的重要找矿标志等认识,对今后煤下铝找矿具有一定借鉴意义。
Through research on the successful prospecting of the large-scale bauxite mine of Wumenggou underclay(coal)bauxite mining area in Shanxian County,Henan Province,made the summary of the geological characteristics,enrichment rules and prospecting indicators of the deposit.The most valuable understanding is that the underclay(coal)bauxite orebodies lay between the Upper Carboniferous Benxi Formation coal-bearing strata and the underlying Middle Ordovician limestone,and that the magenta-iron clay rock is a important prospecting mark for the underclay(coal)bauxite deposit in this area,which has certain reference significance for coal prospecting in the future.
