| 摘 要： | 山西交口县庞家庄铝土矿属于典型的喀斯特型铝土矿，矿体赋存于上石炭统本溪组，其下部为中奥陶统灰岩。矿石以隐晶质结构为主，含少量碎屑结构与鲕粒结构；矿石的结构特征显示一些风化物质经过了一段距离的搬运，并且矿体在晚期遭受了构造变形作用。x射线衍射分析显示铝土矿石中的主要组成矿物为硬水铝石、高岭石、赤铁矿、针铁矿、方解石与少量...

| Abstract: | The Pangjiazhuang bauxite deposit in Jiaokou county,Shanxi is a typical karst bauxite deposit.The orebodies occur in the Upper Carboniferous Benxi Formation,which is underlain by Middle Ordovician limestones.The ore is dominated by pelitomorphic textures,with few detrital textures and oidic textures.These textural features suggest that the bauxitic soils were transported over a short distance and suffered tectonic deformations in the late stage.X-ray diffraction results show the principal minerals are diasp... |
