豫西郁山铝土矿含矿沉积层序研究

摘要

The ore-bearing bed of bauxite in western Henan is in benxi formation of Lower Permian, belonging to G layer bauxite of North China.There are four drill holes in the study area, each in defferent line of exploration section. Drill hole 1970 has more complete bauxite profile, divided into nine layers;drill hole ZK701 can be diviede into 9 layers; drill hole ZK3102 has more simple bauxite sequence, may divided into 6 layers; drill hole ZK501 may be divided into 10 layers from floor to roof. Research on the sequence of bauxite has practical significance for bauxite exploration in this area as well as for identifying ore-bearing bed while drilling logging.%豫西铝土矿含矿层位为下二叠统本溪组，属华北 G 层铝土矿。本区研究共涉及4个钻孔，分别位于矿区不同勘探线上。钻孔1910为本次研究中铝土矿剖面发育比较完整，分为9个层位；钻孔 ZK701可以划分为9个层位；ZK3102钻孔中含铝岩系段层序相对比较简单，可大概划分为6个层位；ZK501钻孔剖面大概从底板到顶板岩石可以划分为10个层位。研究铝土矿的沉积层序对该区域的铝土矿勘探、钻探编录时识别含矿层等都具有很强的指导作用。
