| 摘 要： | 河南省的铝土矿赋存于石炭系本溪组中，按成矿物质来源可分为原地型和异地型两种类型.成矿物质来源主要与古风化壳的地形形态有关.矿床规模、矿体形态、矿石质量主要受奥陶纪-石炭纪之间的侵蚀间断时间、侵蚀间断面形态及距古陆的距离控制.滨海-湖-沼泽相是铝土矿形成的有利环境.陕县-新安一带是寻找隐伏型铝土矿的有利地区.

| Abstract: | The bauxite deposits in Henan Province occur in Carboniferous Benxi formation. Based on the sources of ore-forming matters, the genesis of the deposits can be classified into two types, i.e. in-situ and exsitu. The sources of ore-forming matters are closely related to the topography of ancient weathering crust. The deposit scale, orebody occurrence and ore quantity are mainly controlled by the erosion interval between Cambrian and Carboniferous, the appearance of erosion surface and the distance apart from ... |
