摘　　要：河南中西部地区铝土矿资源丰富。渑池县礼庄寨铝土矿床赋存于上石炭统本溪组中，含矿岩系及矿体严格受古地形及向斜构造控制，共形成三层工业矿体，矿体呈似层状、不规则状。铝土矿是由于海侵作用，接受陆源物质的汇入，在海湖盆地中逐渐沉积形成的。The bauxite is rich in central and western regions of Henan Province. Such Lizhuangzhai Bauxite Mine in Mianchi County occurs in the Mid-Carboniferous Benxi Formation, and mineralization zone or ore body is strictly controlled by the Paleo-topography or syncline structure, three-layered economic ore bodies are formed with the lentoid or irregular shape. The preliminary conclusion is the bauxite is deposited gradually in the Paleo- sea basin, where the transgression is taken place and the terrigenous materials from the Paleocontinent is imported immediately.
