矿床概况河南某铝土矿矿体走向东西连续延展,向北北东作緩倾斜延伸地下,构成單斜构造。该区域内所出露的岩层,最古老者为太古界泰山杂岩,最新的为三叠纪红色砂岩页岩及第四纪黄土。中间除志留泥盆及中下石炭纪地层缺失以外,其他各纪岩层均有沉积,铝土矿即存在于奥陶纪侵蝕面上,呈假整合接触,其上为 Mineral Deposit Overview A bauxite ore body in Henan Province extends continuously east-west and extends gently to the north and north east to form a monoclinic structure. The most exposed rock formations in this area are Archean Taishan complex, the most recent being Triassic red sandstone shale and Quaternary loess. In addition to the Silurian Devonian and the Middle-Lower Carboniferous strata, there are all other stratigraphic sediments deposited in the middle. The bauxite exists in the Ordovician erosion surface and presents as a false integrated contact.
