| 摘 要： | 河南省三门峡境内铝土矿床是产于奥陶系灰岩之上的一水硬铝石型沉积型铝土矿床，铝土矿矿体形态与古岩溶侵蚀面有着密切的关系，呈层状-似层状、透镜状（扁豆状）、溶斗状等，矿体的形态严格受古地形的控制.矿石类型主要为砾屑状、砂（粒）状、蜂窝状、豆鲡状及致密状铝土矿，以及它们之间的复合类型.矿床的形成主要受本溪组地层、构造、古地理等多种条件控制.

| Abstract: | The bauxite deposits in Sanmenxia area, Henan Province, are of diasporic sedimentary type formed on Ordovician limestone. The forms of bauxite orebodies are closely related to the paleokarst erosion surface, occurring as stratiform-stratoid, lentiform (podiform) and doline form, which are strictly controlled by paleotopography. The ore types are mainly rudaceous, gravelly, alveolar, pisolitic and compact bauxites, and the composite types as well. The forming of deposits is controlled by multiple conditions mainly as strata of Benxi Formation, structure and paleogeography. |
